Aggregated Ethernet interface remains up instead of down after deleting loopback and ae interface ip on neighbor while verifying BFD sessions on router Product-Group=junos: Aggregated Ethernet child interfaces with LACP configurations are not timing out even if peer is gone and not sending any bridge protocol data unit (BPDU). the micro BFD that is running over the AE interface tears down the Bidirectional Forwarding Detection (BFD) session and does I'd like to temporarily mix 10Gb and 40Gb interfaces on an ae interface during an upgrade--can I safely do this? What do I set link-speed to? Junos: 15. R1. When a customer edge (CE) device in an Ethernet VPN-Multiprotocol Label Switching (EVPN-MPLS) environment is multihomed to two or more provider edge (PE) devices, the set of Ethernet links that connect the devices comprise an Ethernet segment. Symptoms. Interfaces configured as redundant Ethernet interface LAGs typically have between 4 and 16 This article explains how to identify an interface which has changed state on an EX series switch. Article ID KB34635. Learn how to provide link protection for aggregated Ethernet Interfaces and configure the minimum number of links in an aggregated Ethernet interfaces bundle. ge-0/0/0. 0: 04-05-2024 by Anonymous Hi, I've a EX4550 (JUNOS 12. Learn about Ethernet technology used to broadcast traffic on security devices, static ARP entries, creating and deleting the Ethernet interface, and enabling and disabling the promiscuous mode on these interfaces. 3ad ae11; } LACP interface might go down when a sub-interface configuration is added and committed to the AE interface Product-Group=junos: On all MX150 platforms, when an Aggregate Ethernet (AE) interface is configured with LACP and adding a sub-interface configuration under the AE interface causes the LACP down leads to traffic loss. Interface does not come up; Interface flapping. Customers may notice that when an interface is down, the " show ethernet-switching interface " output always displays "blocked by STP" for the interface, which could be misinterpreted as indicating a spanning tree issue. The inline service interface is a virtual physical service interface that resides on the Sep 14 20:01:55 ex mib2d[14295]: SNMP_TRAP_LINK_DOWN: ifIndex 878, ifAdminStatus up(1), ifOperStatus down(2), ifName aeX. Print Report a root# run show interfaces terse | match ae ge-2/0/8. This is how the ae is configured on the MX104 side to the firewall. Posted 07-01-2022 05:50. Model: srx1500 Junos: 15. 4R1 a new feature is introduced that allows the configuration of the hold-time on the ae interface Symptoms Due to some legacy configuration in their network, the customer is asking about the behavior of having the hold-time configuration in the physical members interface, ae interface, or in both physical members and ae ARP and MAC address tables normally stay synchronized in MC-LAG configurations, but might get out of sync under certain network conditions (such as link flapping). 0's Link status is down? and when I show interfaces terse there do not have xe-0/2/3 and xe-1/2/3, and do not list all other xe-* interfaces. Anybody can suggest if LACP is supported on vMX or not? my vMX version 14. Last %DAEMON-4-SNMP_TRAP_LINK_DOWN: ifIndex 1105, ifAdminStatus down(2 After doing so, I see a strange interface unit that was automatically created by Junos. Log in. I use the 740-021309 (10GBASE-LR 10km 1310nm 70C) modules. Specify the hold-time value to use to damp shorter interface transitions milliseconds. 0 - unit 0 aka logical interface 0. When I try show interfaces ae0 terse Verify LAG (Link Aggregation Group) of a Juniper Networks EX Series switch is UP and troubleshoot it if it is not. LACP is one method of bundling several physical interfaces to form set interfaces ge-0/0/24 ether-options 802. To set the MTU on an aggregated interface: LACP and AE interfaces basic configuration with examples. Last Updated 2023-12-06. 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. This AE connects to our backbone. The juniper shows athe An interface in JUNOS can have multiple logical interfaces. 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 Juniper QFX3000-G and QFX3000-M Qfabric systems have reached end-of-support (EOS). This article provides information on how to set the MTU on an aggregated interface. Without AE-specific configuration, the interface will not be shown in the show interfaces terse output. Define tracing operations for individual interfaces. This article helps networking heroes familiar with Cisco configuration and need more understanding on equivalent Juniper command sets. ( On MX Series routers with multichassis aggregated Ethernet (aeX) interfaces, displays information about the aeX interfaces. 2 interface ae0 On peers with multichassis aggregated Ethernet (mc-aeX) interfaces, use this command to display information about the multichassis aggregated Ethernet interfaces. Configure the Link Aggregation Control Protocol (LACP) parameters for interfaces. The customer had requested to test the knob for link speed and auto-negotiation. 300. this still shows as link down, even though the remote end is running. Verify AE interfaces by using following command, Learn about the issues fixed in this release for QFX Series. 0 ge-2/0/8. The remote side is a Tintri VMstore T-850.
