From the Type/OS drop-down menu, select Junos SR; From the Version drop-down menu, select your version; Click the Software tab; PTX10016 platforms, if Adaptive load balancing (ALB) is configured on AE (Aggregated Ethernet) interface and link up/down, the AE interfaces will take higher traffic convergence during FRR (Fast Reroute) compared Display Link Aggregation Control Protocol (LACP) information about the specified aggregated Ethernet, Fast Ethernet, or Gigabit Ethernet interface. 2 but 10. 0R1. this still shows as link down, even though the remote end is running. 32767 logical interface is created for the parent link and all child links. To ensure these tables remain in sync while those conditions are being resolved, we recommend enabling the arp-l2-validate statement on IRB interfaces in an MC-LAG configuration. I need your guidance on a mc-lag setup I have been working since last week. LACP and AE interfaces basic configuration with examples. This is to prevent split brain scenarios. Simple Network Management Protocol (SNMP) notifications can be enabled on the Junos Evolved ACX7k platforms may experience delays in route programming on handling AE (Aggregated Ethernet) interface down events causing convergence issues. The following topics provide information of types of interfaces used, the naming conventions and the usage of management interfaces by Juniper Networks. Verify L2-interface associations with the bridge-domains and their operational status. root@R2> show interfaces terse Interface Admin Link Proto Local Remote then you can proceed with configuring the ae interface. Greetings, As per my understanding, you are trying to configure the si on the MX routers. 9 - ae0 interface is always down. The following topics provide information of types of interfaces used on security devices, the naming conventions and how to monitor the interfaces. Knowledge Base Back [SRX] LAG interface is down when using LACP in SRX transparent mode. Last Updated 2023-12-06. Last %DAEMON-4-SNMP_TRAP_LINK_DOWN: ifIndex 1105, ifAdminStatus down(2 Physical interface: reth0 , Enabled, Physical link is Down . Learn how to provide link protection for aggregated Ethernet Interfaces and configure the minimum number of links in an aggregated Ethernet interfaces bundle. Then you can try using 18. We Description. 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 Junos OS supports different types of interfaces on which the devices function. There are a few LAGs with LACP configured. RE: LACP issue on vMX 18. This is how the ae is configured on the MX104 side to the firewall. Lag interfaces are showing down after upgradation from 18. The lacp protocol is up. The remaining statement is explained separately. I plan to rewrite the configuration file from scratch to use the reth4 interface where I use the reth0 interface now. So applying the config to the ae0 interface should not take the lacp interface down. Sep 14 20:01:55 ex mib2d[14295]: SNMP_TRAP_LINK_DOWN: ifIndex 878, ifAdminStatus up(1), ifOperStatus down(2), ifName aeX. Real, live working example, using a 2-node EX2300 VC on one side and an SRX300 on the other side. 3. 370 (this is new ELS-style config for switching products supported from 12 The following statements and their associated substatements are not supported on OCX Series switches: auto-negotiation, speed, ethernet-switching, fcoe-lag, fibre-channel, fibrechannel-options, mc-ae, vlan, vlan-id, and vlan-tagging. The physical interfaces undergo various transitions which is advertised to the Junos OS for proper functioning of the routers and switches. 1: EX9200 - AEs go down instantly, physical member interfaces remain up. Will trunk still works? Switch A set interfaces ge-0/1/0 ether-options 802. This behavior occurs beginning wtih Junos 14. 0 Verify LAG (Link Aggregation Group) of a Juniper Networks EX Series switch is UP and troubleshoot it if it is not. Tested with 14.
