Juniper reth interface down. FAB and EM0 interfaces all setup and playing nicely.

Juniper reth interface down Make sure that you setup your max number of redundant interfaces as follows: On device A: {primary:node0} # set chassis cluster reth-count <max-number> -for first interface in the group (on Device A) 对于 srx300、srx320、srx340、srx345、srx380、srx1500、srx1600、srx2300、srx4100、srx4200和srx4300设备，可在 机箱群集 部署中的所有冗余以太网 （reth） 接口之间配置的逻辑接口总数为 1024。. Hi I have configured a RETH interface on my SRX cluster across 2 interfaces. 210 255. 200/24 user@srx# set interfaces reth1 redundant-ether-options redundancy-group 1 user@srx# set interfaces reth1 unit 0 family inet address 192. In some scenarios, it is difficult for customers to setup reth interface in SRX chassis cluster; they have to use local interfaces instead of the reth interface. Redundancy group 0 remains primary on the node on which it is presently Third - If is not possible to use reth and irb in same time, for example for reth0. 上記の診断結果より、バックアップ用ルーティングエンジン（ホスト1）の管理インタフェースem0にシャーシアラームが発生し、プライマリ用ルーティングエンジン（ホスト0）には発生していないことが確認されました。 Specify redundant Ethernet interfaces (reth) and assign local (child) interfaces to the reth interfaces. a Reth interface is a redundant ethernet interface. Before you begin: This article helps networking heroes familiar with Cisco configuration and need more understanding on equivalent Juniper command sets. 111 and irb. LACP and AE interfaces basic configuration. 2 but 10. thanks in advance Hi Robbie, The following statement answers your query :- In the event of a legitimate control link failure, redundancy group 0 remains primary on the node on which it is currently primary, inactive redundancy groups x on the primary node become active, and the secondary node enters a disabled state. 0 up down bridge <--- Solution The hold timer enables interface damping by not advertising interface transitions until the hold timer duration has passed. See if it comes up then. ] Before you begin: Alternatively you can interface to another SRX cluster configured the same way (obviously one side should be LACP active and the other passjve) and connect node0 interfaces to node0, and node1 interfaces to node1, but its a bit average TBH because it still relies on physical line state only for RG transitions and so caters for fewer types of A month back there was a power outage taking both the nodes down. However, contrary to intuitive assumption, the parent RETH interface will stay up for 10 or more seconds. 0 interface still 0? Looks like some packets are being dropped. This new one is showing as link down even though one of the two member Perform the following tests to check if the em0 management interface is down on the primary Routing Engine or the backup Routing Engine: Run the show chassis alarms command. KB79516 : How to change interface throughput speed down on SRX300 2025 Juniper Networks, Inc. A workaround is also suggested that could help avoid this scenario. 7. Then, if 1 interface fails, IPS will be still functional with reduced BW, of course. I believe in JUNOS 10. KB32065 : [Archive] SRX300 series interface down after disabling auto This article provides information on how to use the local interface, instead of the reth interface, in a SRX chassis cluster. 1/24, LAN = 192. and that st0. When connecting SRX and QFX5110 with 1G link using fiber SFP, the physical interface is down on SRX. To configure Reth Interface in Junos (SRX), you have to first understand the basics of SRX HA basics. Reth LAG interfaces combine characteristics of reth interfaces and set interfaces ae0 unit 0 family ethernet-switching port-mode trunk set interfaces ae0 unit 0 family ethernet-switching vlan members 10 {primary:node0}[edit] root# run show interfaces terse | match reth ge-2/0/8. This keeps systems communications working On my srx i have a reth interface configured with vlan-tagging for multiple vlans and i want to enable OSPF. Sascha To configure a RETH interface for a specific speed/duplex setting, you have to upgrade to at least 11. 4R10. This section includes the following topics on SR-IOV for a vSRX Virtual Firewall instance deployed on KVM: Para SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200 e dispositivos SRX4300, o número total de interfaces lógicas que você pode configurar em todas as interfaces Ethernet (reth) redundantes em uma implantação de cluster de chassi é de 1024. Thanks in advance for any help you can provide. 32767 up down aenet --> reth8. I have to configure a route-based ipsec vpn. 2 the IRB interfaces remain up/down even though all the physical and RETH interfaces are up/up. Maybe some application is interrupting the process, ultimately causing a timeout. And Ive configured a new reth int on a pair of clustered srx650 running junos 10. - When EX member 1 is DOWN,reth1 is DOWN and you wont be able to ping 10. chassis { cluster { control-link-recovery; reth-count 2; redundancy-group 0 { node 0 priority 100; node 1 priority 50; } redundancy-group 1 { node 0 priority 100; node 1 priority 50; ip-monitoring { family Display the state of the router's interfaces. 4R1. 2/24 Regards, Sam There are two types of switching modes: Specify either red, yellow, or ignore to display when the link is down. Configure the Redundant Ethernet interfaces (Reth interfaces) and assign the Redundant interfaces to a zone. The reth interface has 4 interfaces from each node. I am unable to get the reth to show as up, showing interfaces terse shows the reth as down. The reason for the fabric interfaces is to sync states (Juniper calls this RTO - Real-time objects) so whenever a failover occurs, the backup firewall will have all states of the primary firewall (session, NAT etc. It was late last night when I finally figured out that it was the result of JunOS 22. Follow the steps as given below to troubleshoot and fix the Fabric Link Status is showing down . I added a new reth interface on an SRX cluster this weekend. Each SRX will have 1(or more) interfaces attached to a Reth group. I then came to be setting up my Reth's and figured LACP from my L2 VIRL switch would be the way to go in order to failover my cluster. A reth interface is a virtual interface. 1/24 Interface is not showing up in ethernet-switching interfaces: 0> show ethernet-switching interfaces Interface config: unit 0 { family ethernet-switching { port-mode trunk; vlan { members [ vlan-lab-a vlan-lab-b ]; } } } VLAN If you really want to use minimum-link knob for RG failover then you have to use 11. For more information, see the following topics: Description. Other RG's are associated with RETHs which are associated with physical interface(s). In cases we have seen when the above is not oresent we have seen issues. Please refer below KB for ethernet-switching with chassis cluster. root@SRX_HighEnd> show chassis cluster interfaces Control link 0 name: em0 Control link 1 name: em1 Control link status: up Fabric interfaces: Name Child-interface Status fab0 ge-0/0/5 down fab0 Fabric link status: down Solution. This new one is showing as link down even though one of the two member interfaces is up. This article provides information on how to failover data plane without the reth interface. I mean to delete Reth interface and add the ports from reth0 to IRB interfaces and then to add the IRB interfaces to proper security zones. One such commonly used command in Cisco is Juniper Shutdown Interface or Try disabling each interface then re-enabling one-by-one: set interfaces ge-0/0/8 disable commit delete interfaces ge-0/0/8 disable commit. 1 family inet . 1R4, 11. You are here: Network > Connectivity > Interfaces. 0 ge-2/0/9. node0: node1: Add. Is it wise to add only reth1 in ospf area 0, or do i need to add each of the interfaces (reth1. active/active is achieved by having an RG1 and RG2, assign the reths evenly to each, and then I am using RETH interfaces - the irb is for the VLAN the reth interfaces (and other ports which aren't reth, are just simple connections) are in. 2 up down inet 1. Let me know your thoughts. I am using a reth interface for the gateway interface, so that is ok, but the example HERE for "Configuring Redundancy Groups for Loopback Interfaces" seems to indicate that I also have to create a st0 interface that is redundant. One on each node. 168. I have two Juniper SRX 300 firewalls running Junos 22. Or in other words its not supported on reth/ae interfaces. 10. In JunOS there are two types of interfaces, In this article, we will examine how the VPN monitor configured on the SRX cluster hub takes down the st0. Repeat for each physical interface and do the reth interface last. RG2: For TRUST ZONE reth interface. Is that correct, that it is necessary to maintain HA, or IEEE 802. You need to specify the total number of interfaces in the chassis cluster before redundant Ethernet interfaces are created. 3ad ae1 set interfaces ge-0/0/2 ether-options 802. How should I configure the device Before you begin: After doing so, I see a strange interface unit that was automatically created by Junos. Interface monitoring monitors the state of an interface by checking if the interface is in an up or down state. Symptoms. interface-control: para agregar When we apply the monitor traffic interface reth3. please clarify what is the Reth Interface. SRX support local interfaces in chassis cluster. root@SRX1500-cluster> show interfaces reth0 Physical interface: reth0 , Enabled, Physical This article describes the issue of the RETH interface being up for 10 or more seconds, even after the child interfaces are physically down. Chassis clustering works by taking two SRX nodes and merging them to make a single logical chassis. 1 ge-5/0/8 255 Down / Down 2 ge-0/0/8 255 Down / Down 2 . VLAN tagging and VLAN-ID in the reth interface is sufficient. 1X44-D10 aggregation was not supported on For an SD-WAN site with dual CPE cluster, you can use a redundant Ethernet (reth) interface to connect the SRX Series Customer Premise Equipment (CPE) devices to an EX Series switch or an access point (AP). 0 ge-2/0/8. Description. RG1: For UNTRUST ZONE reth interface. The article points out that this behavior is expected, and indicates that for the RETH interface A redundant Ethernet (reth) interface is a pseudo-interface that includes minimum one physical interface from each node of a cluster. What is Impact of Redundancy Group 0 (RG0) Failover. A redundant Ethernet interface contains a pair of Fast Ethernet interfaces or a pair of Gigabit Ethernet interfaces that are referred to as child interfaces of LACP and AE interfaces basic configuration with examples. In the actlog, that particular interface shows (in red) “ifOperStatus: down -> up” at each poll. A redundancy group 0 failover implies a Routing Engine failover. Because the functionality of a redundant Ethernet interface relies on the JUNOS aggregated Ethernet framework, you can think of it as a special aggregated Ethernet interface. 2R2, or 11. . 1 up down inet 10. how to achieve this . 0 interface after unsuccessful reachability attempts to the remote peer because of physical interface flapping. The reth interface of the active node is 【解決方法】Juniper SRXでrethがUpしない SRXでLACPを設定しましたが、対向のL3SW（Cisco）と通信できていませんでした。確認するとrethがdownしていました。 トラブル時の構成図は以下の通りです。 Junip IEEE 802. node0 came online first, and node for some reason came back an hour later (as determined by show system uptime). Also, the command "set chassis cluster reth-count 10" exists in the configuration. In you configuration I see that you need a L2 interface (running ethernet-switching) to be able to have multiple switches connected to same node. admin@srxA-1> show interfaces st0. If you do not specify an interface name, status information for all interfaces is displayed. When a hold-down timer is configured for a parent RETH interface Ive configured a new reth int on a pair of clustered srx650 running junos 10. In such a scenario, if the switch crashes or loses power, both the child interfaces go down at once. user@srx# set chassis cluster reth-count 2 user@srx# set interfaces reth0 redundant-ether-options redundancy-group 1 user@srx# set interfaces reth0 unit 0 family inet address 10. 2 JUNOS and you will use minimum-link knob with interface monitor of reth interface. When you initialize a device in chassis cluster mode, the system creates a redundancy group referred to in this topic as redundancy group 0. ホールドタイマーは、ホールドタイマー時間が過ぎるまでインターフェイス遷移をアドバタイズしないことで、インターフェイスダンピングを有効にします。親 reth インターフェイスにホールドダウン タイマーが設定されており、プライマリ子インターフェイスがアップからダウンになる Interface Admin Link Proto Local Remote vlan up up vlan. 2 that I was having problems, so I've not yet tested 22. 10, reth1. So what do you think should I create three RG. A redundant Ethernet interface contains a pair of Fast Ethernet interfaces or a pair of Gigabit Ethernet interfaces that are referred to as child interfaces of Welcome to the Juniper subreddit, a Subreddit dedicated to discussing Routers, Switches and Security Appliances manufactured by Juniper. HTH No - the reth interface on the SRX only allows a single interface to be active (forwarding) at one time, whereas an AE interface expects both interfaces to be up. All rights Due to “reth-count 3”, the last interface which is reth3 is not working. 0, we don't see the traffic that passes through this interface. Is the In some high-availability SRX deployments, the child interfaces of a RETH interface are connected to the same switch. Solution. Solution Basically, I didn't configure any vlans on the SRX since the switches I'm using are all unmanaged So I decided to create different reth interfaces instead. 1. Disabling an interface: Disabling an interface in Junos is equivalent to interface shutdown. In chassis cluster mode, aggregated Ethernet interfaces (ae) and redundant Ethernet interfaces (reth) coexist. Use this command for performing router diagnostics only, when you are determining whether the routing protocols and the Junos OS differ about the state of an interface. I've got a lab built in eve-ng with a vSRX cluster built however im having issues with the reth interfaces and wanted to see if anyone has had these problems before. KB32901 : [SRX] Physical interface is down when using 1G link and fiber SFP between SRX and QFX5110. How to failover data plane without the reth interface? Solution. The vlan configuration is in my original post, but basically it looks like this set vlans server vlan-id 9 set vlans server l3-interface irb. Thanks. This topic discusses various troubleshooting scenarios. Before you begin: Hi all, I've been on two Juniper courses recently and started to work on my labs to prepare for my exams and just get some more experience. Unfortunately, PR1121354 is a hidden PR, so you'll need to contact JTAC to get additional details. I have two SRX3600 cluster in A/P. Upgrading from 19. 3ad link aggregation enables you to group Ethernet interfaces to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. A reth interface of the active node is responsible for passing the traffic in a chassis cluster setup. This article provides information about Ethernet switching support in cluster mode for SRX Branch devices and SRX1500 Series devices. The other physical interfaces are Up. 3 other reth are working fine. Only one Node will have any specific RETH as primary; other side will always be in secondary. Hi Experts . A reth interface of the active node is responsible for In the extensive interface output, you can see that obly one member is down: jbelles@blah-node0> show interfaces reth7 extensive Physical interface: reth7, Enabled, If it is enabled on one device (SRX) and Not enabled on Switch then Reth interface will not come up. When a RETH interface is configured only on one node, its status is always down. Display status information about the specified aggregated Ethernet interface or redundant Ethernet interface. Juniper Networks Support SRX - High Availability Configuration Generator reth Interfaces & Ports. 0 statistics Logical interface st0. 4 -> 21. 26. Hey all, I've been labbing a concept on clustered vSRX, with back-to-back reth interfaces and using ip-monitoring to facilitate failover between the reth interfaces when a failure occurs that does not include a physical interface going down (interface monitoring). KB30947 : [SRX] LAG interface is down when using LACP in SRX transparent mode ppp-over-ether set interfaces reth0 unit 100 vlan-id 100 set interfaces pp0 unit 0 ppp-options chap default-chap-secret juniper set interfaces pp0 unit 0 ppp-options chap local-name client1 set KB82031 : [SRX] 'Vlan-tags' Options Not Available for AE and RETH この問題を解決するために. When you are failing over to another node, you will have to manually switch the RG0 to the same node where you are switching RG1 interfaces in that case this EWF will work. 32767 . It is not ana dvisible design to have two interfaces on the same broadcast domain. Configuring AE: KB33267 : [SRX] RETH interface is down when it is configured only on one node. Security Zones & Logical Interfaces Security Zones. What is best practice to do this. 3ad ae2 set Juniper documents for configuring Reth and AE interfaces on SRX series use the gigether-options hierarchy: Configuring Reth: Chassis Cluster Redundant Ethernet Interfaces . The sum needs to be 255 BUt thinking of it from newtwork terms, two interfaces can reach the same boracast domain, now the SRX would choose the interface with the highest interface ID as the prefereed outgoing interface. 0 must be configured under interfaces error: configuration check-out failed {primary:node0}[edit] I can't remove this reth7. Reth LAG interfaces combine characteristics of reth interfaces and Reth interface and its childs are up/up. We can see the VPN traffic, but the security sessions that are already up don't appear when we apply the monitor command. Every interface transition that occurs during the down hold-time is ignored. 30) in the vlan for them to begin sending and responding to OSPF hello packets. 20 and reth1.

From configuration mode we can run root@# set interface-name speed 100m To monitor the cluster, you need to discover the redundancy groups. 209/29 - VSS ! interface Port-channel60 ip address 172. Reth interfaces are generally used as L3 interfaces. 1 is bound to a zone. set interfaces reth6 redundant-ether-options minimum-links 1 set interfaces reth6 redundant-ether-options lacp active set interfaces reth6 redundant-ether-options lacp periodic slow set interfaces reth6 unit 0 family inet address 172. 10 (one of the firewalls is newer bought this year, the other is a few years old) All RETH interface link lights and FAB link on node 1 go down (FXP1 is still lighting) The setup you have requires at least two interfaces to go down before failover occurs. It will be active on one of the two nodes only and it has the ability to move/failover to the other node. The interface state isn’t changing and has remained up since it was built. Step 1: Configure the aggregate interface: set interfaces <ae interface> unit <unit id> set interfaces <ae interface> aggregated-ether-options lacp <active/passive> Example: user@host# set interfaces ae1 unit 0 Before you begin: In this case, a single device in the cluster is used to route all traffic while the other device is used only in the event of a failure (see Figure 1). Hi, Prior to this, the interface is normal, Through the command "show interfaces extensive | match flapp", only the Eth1 interface flapp is found. BUT, only one of the SRX's will be active at a time, so only 1 set of interfaces will work at one time. In the case of a Routing Engine failover, all processes running on the primary node are killed and then spawned on the new primary Routing Engine. This scenario is supported in SRX HA: Active/Passive State (Control): Chassis Clustering is working in the HA mode by using JSRP. Check the following configuration parameters: SRX is set to switching mode ("show ethernet-switching global-information" can be used) IRB interfaces have a valid IP address It's my first time configuring Juniper devices and I would like to ask some help if you may. Reth interfaces are configured when SRX device is in HA (High Availability) mode. Regards, c_r My question was if reth interface of TRUST OR DMZ down then only that interface should failover BUT if reth interface of UNTRUST down then everything should failover. Sometimes we need to reduce the throughput speed on one interface on the SRX300 series Firewall to 100 mbp for example. 255. 1/25, these are my subnets for those reth interfaces. If you try to configure speed/duplex setting on the member interface of a RETH interface, it still shows auto-negotiation. Para dispositivos de SRX5800, SRX5600, SRX5400 e SRX4600, o número total de Your reth interface configuration looks perfect. it is directly connected to any port (like any switch port) and what is the use of it?P Groups are created with the Reth interfaces in them that failover as a group between the cluster members when a failover event occurs. 248! interface GigabitEthernet1/4/4 KB87323 : Physical interface goes to an up/down state as soon as it's added to a LAG on an ex4100 KB82031 : [SRX] 'Vlan-tags' Options Not Available for AE and RETH Interfaces KB75705 : [SRX] Flowd may crash when jflow v9 is configured The traffic path failover to node1 by OSPF is successful; however the time of failover is much longer than the reth interface, it is decided by how long OSPF takes to find out if the interface is down and re-calculate. They recovered as power came back, and the chassis cluster is back on. For an SD-WAN site with dual CPE cluster, you can use a redundant Ethernet (reth) interface to connect the SRX Series Customer Premise Equipment (CPE) devices to an EX Series switch or an access point (AP). 1X44-D10 aggregation was not supported on Description. Nat and security policies are also in place for these subnets/interfaces. What could be the reason for RETH interface not getting created? Regards Saif-----SHIVAJI CHAVAN With JunOS 22. The requirement is to hard code the RETH interface to 100/Full; however, there seems to be no option on the RETH to specify the setting. A redundant Ethernet (reth) interface is a pseudo-interface that includes minimum one physical interface from each node of a cluster. - The minimum-link will bring down the reth interface - The interface monitor of that particular reth interface will do the failover of RG from node0 to node1 . I can unplug any of the switch now without downtime. Is that correct, that it is necessary to maintain HA, or root@SRX1500# run show interfaces reth0 error: device reth0 not found Even in "run show interface terse" command, its does not show any RETH interface. When using the Disable command, the interface will be administratively down without impacting the configuration on that interface. 3ad ae1 set interfaces ge-0/0/1 ether-options 802. As is the case for all redundancy groups, Configure Ethernet redundancy options for a chassis cluster. 0/0 next-hop 10. Cuando se configura un temporizador de espera para una interfaz RETH principal y la interfaz secundaria principal va de arriba abajo, se activa el temporizador de tiempo de espera inactivo. No need to configure separate VLANs via the L3 interface. 1/24, WIFI = 192. 0. But you can have two SRXes providing next-hop redundancy without a chassis cluster, so long as your traffic flow is not asymmetric at any point. We then configure Redundant Ethernet (Reth) interfaces – these are aggregate interface-like constructs that consist of set interfaces reth1 vlan-tagging set interfaces reth1 redundant-ether-options redundancy-group 1 set interfaces reth1 unit 100 vlan-id 100 set interfaces reth1 unit 100 family inet address 1. Can anyone explain to me what that is? terse interface list: ge-2/0/8. so you need to disable LACP on both Devices SRX and Switch, That does However, the reth does not come up, but the constituent physical interfaces do come up. 4 you can now configure AE interfaces on the SRX as RETH members meaning you will have 4 links between the SRX and the EX, but only one AE can be active at any time. FAB and EM0 interfaces all setup and playing nicely. When a hold-down timer is configured for a parent RETH interface and the primary child interface goes from up to down, the down hold-time timer is triggered. unit 0 is the actual vlan interface, unit 32767 just appeared. When one or more monitored interfaces fail, the redundancy group fails over to the other node in the cluster. 3. When I configure each interface as a layer 3 interface, it works fine, I seem to be missing something. You should be able to ping to the reth interface IP. In some high Without the interface-monitoring configuration: If child links in a reth on a node go down, the reth interface will go down too, as shown below: reth1 Down 1 <--reth is down and The hold timer enables interface damping by not advertising interface transitions until the hold timer duration has passed. Does anyone know how I can prevent this from being hi-lighted in each poll? Thanks in advance for The 10-GigabitEthernet (XE) physical interfaces comes up and are operational, however when 10-Gig interface is added to redundant Ethernet (reth) interface, reth remains down. Also you can do a > monitor traffic interface reth2. 2. Symptoms Reth interface and its childs are up/up. You'd create tagged logical interfaces on your firewalls, and then assign to reth interfaces. 252. Check the following configuration parameters: SRX is set to switching mode ("show ethernet-switching global-information" can be used) IRB interfaces have a valid IP address This message was posted by a user wishing to remain anonymous. Redundancy group 0 manages the primacy and failover between the Routing Engines on each node of the cluster. Ive confirmed that my reth-count is set appropriately. The Disable command should be used to take interfaces down and not deactivate. After doing a rollback, those reth units that were missing were up again and passing traffic. This message was posted by a user wishing to remain anonymous. Members Online • fatman00hot. IEEE 802. 3ad リンク アグリゲーションを使用すると、イーサネット インターフェイスをグループ化して、リンク アグリゲーション グループ(LAG)またはバンドルとも呼ばれる単一のリンク層インターフェイスを形成できます。Reth If yes to both then rather than using 1 IPS interface as ingress and 2nd interface as egress, You can aggregate both IPS interfaces into a LAG and configure 2 VLANs across this LAG: 1 VLAN for ingress and 2nd for egress. The reth interface of the active node is jucao@srwp01jfw020-new# delete interfaces reth7 unit 0 {primary:node0}[edit] jucao@srwp01jfw020-new# commit [edit security zones security-zone XO] 'interfaces reth7. Untrust = 1. My requriement is that as long as two physical interfaces out of four on primary nodes are up then redundancy group should be active on primary node but if three physical interfaces out of four are down then redundnacy group should failover to secondary node. 2 is not a supported jump. 111 does that mean that all configuration for reth0 it should be change to IRB. Any ideas why an reth would show as down when one member is up? set chassis aggregated-devices ethernet device-count 10 set interfaces ge-0/0/0 ether-options 802. ". For example, the set chassis cluster reth-count 2 allow you to create two reth interfaces (example: reth0 and reth1) Before you begin: All the reth interfaces should ahve the member interfaces where you are having the RG0 master. Thanks Spuluka, but I found that the traffic that passes through the firewall can't appear in the monitor command, we can see it by the (show security flow session) and if we need to export it we should take a PCAP from both interfaces (reth, and ST) for example, and merge using Wireshark, because from each interface it is capture just one way Before you begin: The 10-GigabitEthernet (XE) physical interfaces comes up and are operational, however when 10-Gig interface is added to redundant Ethernet (reth) interface, reth remains down. However, if you decide to use stream logging vs. When a failure occurs, the backup device becomes primary and controls all forwarding. However, the interface is up QFX5110. set chassis cluster reth-count 4 set chassis cluster redundancy-group 0 node 0 priority 200 set Welcome to the Juniper subreddit, a Subreddit dedicated to discussing Routers, Switches and Security Appliances manufactured by Juniper. Specifically a 'reth' interface, no. Juniper SRX - Interface monitor issue the LED status light is green but the interface shows down in the CLI , if I pull and put back in both interfaces in a RG neither come back. 0 up up aenet --> reth1. For more information, see the following topics: I dont think you are understanding RETH interfaces properly, which is why you are struggling with this. A redundant Ethernet (reth) interface is a pseudo-interface that includes a physical interface from each node of a cluster. Solution Prior to 12. normal logging (which is still recommended because normal logging bogs down your CPU) then the stream logs will go out one of the revenue interfaces (stream logs go out directly through the data plane, hence no way to push it to the control plane's fxp0). 0 reth1 up down reth1. 1R1. 9. Host-Inbound System Services; Name all ping ssh http https; Experts, I have a quick question here. Configure the loopback pseudointerface in a redundancy group. Make sure that you setup your max number of redundant interfaces as follows: On device A: {primary:node0} # set chassis cluster reth-count <max-number> -for first interface in the group (on Device A) List of all products and applications along with their introduced releases supporting the feature » IP monitoring of reth interface LAGs. The other reth interfaces remain normal. 1/24 CLI commands to change interface throughput speed down to 100 mbp on SRX300 series . For example, the set chassis cluster reth-count 2 allow you to create two reth interfaces (example: reth0 and reth1) Specify redundant Ethernet interfaces (reth) and assign local (child) interfaces to the reth interfaces. RG3: For DMZ ZONE reth interface Its entirely doable to not use fab and reth interfaces, you're just not taking full advantage of the clustering feature. User upgraded from 19. 200. 2 with approach ONE (vlan-tagged subunits on reth interfaces). Example output: Configure the Redundant Ethernet interfaces (Reth interface) and assign the Redundant interface to a zone. set interfaces st0. 0 extensive no-resolve matching "host <vpn-peer-ip>" to see at what message it fails. 75. 251 Reth interface or redundant Ethernet interface is a special type of interface that has the characteristics of aggregated Ethernet interface. 1 because reth0 remain UP I've reconfigured the reth interfaces and now the failover issue was gone. ) so the failover will be as seamless as possible, not just Hi ,I am newbie to juniper srx. 1/24 set interfaces reth1 unit 200 vlan-id 200 set interfaces reth1 unit 200 family inet address 2. 254/24 vlan. down seconds— Mantenga el tiempo de espera para usar cuando una para ver esta instrucción en la configuración. There is no route even when the following is configured: set routing-options static route 0. 4 to 21. It is not normal. Everything's a logical interface with JunOS. The below configuration is from node0/primary SRX and the Cisco IOL switch the reth interface is connected to. 对于 srx5800、srx5600、srx5400 和 srx4600 设备，您可以在 机箱群集 部署中的所有冗余以太网 （reth） 接口上配置的逻辑接口 Thanks Raveen, Why is the counter for Input Packets on the st0. The network is the production environment, submit a configuration, causing lacp Experts, I have a quick question here. SRX cluster with reth interfaces set to ethernet switching and using IRB interfaces for routing is not forwarding the traffic between hosts due to IRB interfaces down; Solution. I think in the Specify the number of redundant Ethernet (reth) interfaces allowed in the chassis cluster. ADMIN MOD Configuring a RETH interface . 0 (Index 69) (SNMP ifIndex 535) Flags: Point-To-Point SNMP-Traps Encapsulation: Secure-Tunnel Input packets : 0 Output packets: 11 Security: Zone: untrust Allowed host Specify the number of redundant Ethernet (reth) interfaces allowed in the chassis cluster. 0' Interface reth7. It is important to follow the upgrade path to avoid these types of unexpected software misbehaviors. 0 up down aenet --> reth8. Just check if you have associated the reth interface with a zone correctly and then most importantly you have ping as host-inbound-traffic system-services setting under either that zone level or reth interface level. c_r [Click the "Star" for Kudos if you think I earned it! set interfaces fab1 fabric-options member-interfaces ge-3/0/2 Now, we'll increase the reth-count to match the number of physical interfaces on the unit set chassis cluster reth-count 8 Now change the redundancy-group to port mapping so that the reth, redundancy group and interface numbers all line up (you'll thank me later): delete redundancy If you go through below URL it states "Flexible VLAN tagging is supported only in plain encapsulation and on Fast Ethernet/Gigabit Ethernet/10-Gigabit Ethernet interfaces. ybhh igypigg ehmyhm qljm njfv rsxe ntsmio gbwv hcvzzjk knrw plfg qckuqk veqig ducnu pbe
