You (the network administrator) can configure damping to reduce the advertisement of physical interface transitions between up and down states. 2. This article clarifies that such an output detail is seen because legacy EX Series switches are designed so. However, I went to set the ae0 interface to 100m as you suggested, and Junos carped at me about the underlying interfaces not being set to the same speed, so when I set the phy intf's to 100m and then the ae0 intf to 100m, the candidate config Hello, I have an ae interface setup on an EX4500. If yes, per my knowledge I think we will not be able to do this configuration on the aggregated ethernet (AE) bundle as you would need a physical interface to carry the L2TP tunnel packets. Knowledge Base Back [MX] AE interface flaps when changing minimum links for bundle and optimize-aggregate-frr is configured. set interfaces ae1 unit 0 family inet address 10. To create the AE interface and to see its details in show interfaces terse output in devices that run Although devices running Junos OS versions later than 16. All logical config should be under the ae interface. If you want to start at ae10, you would need to specify 11 ( since numbering starts at 0). Accounting profiles that specify the characteristics of data about the traffic passing through the routers and switches can also be configured on the physical interfaces. 1 have the flexibility to configure micro BFD with AE interface addresses for BFD session establishment, this feature does not hold good for PTX Series devices. If you do not specify an interface name, status information for all interfaces is displayed. Can anyone explain to me what that is? terse interface list: ge-2/0/8. Posted 07-01-2022 05:50. 3R4. Vrrp primary role changes to backup role when one of physcal interfaces of ae interface on the primary router is down. Sound like something on your pfsense does run lacp correctly Or if you do you want to set the native-vlan-id as you are using that on your non With Junos, you need to specify the number of AE interfaces you want to have supported on the device. Could anybody suggest why lacp enabled interfaces are not coming up in Juniper Virtual lab and Juniper cloud lab vMX device. Keepalive messages help the GRE tunnel interfaces detect when a tunnel is down. Juniper has the corresponding command to disable/enable interfaces in --- Interface in UP UP state triton@neptune> show interfaces ge-0/0/0 terse Interface Admin Link Proto Local Remote ge-0/0/0 up up ge-0/0/0. Then you can try using 18. 0 up up aenet --> ae3. this still shows as link down, even though the remote end is running. This article provides information on how to set the MTU on an aggregated interface. 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. Switch B set interfaces ge-0/0/1 unit 0 family ethernet-switching port-mode trunk Learn about the issues fixed in this release for MX Series. Bundle will be down if you do not add a unit to the ae interface even with child links being up. How Junos handles that kind of condition? Do we need manual config to happen vrrp role change when kind of that condition happens. 33 To make the interface as L3 interface to route packets across the link put the aggregated interface (ae) to "intent" family user@EX# set interface ae0 unit 0 family inet address 10. Will trunk still works? Switch A set interfaces ge-0/1/0 ether-options 802. set interfaces ae1 aggregated-ether-options mc-ae chassis-id 1 set interfaces ae2 aggregated-ether-options mc-ae chassis-id 1 set interfaces ae3 aggregated-ether-options mc-ae chassis-id 1 set interfaces ae4 aggregated-ether-options mc-ae chassis-id 1 set multi-chassis multi-chassis-protection 10. set interfaces ae0 aggregated-ether-options lacp active set interfaces ae0 aggregated-ether-options lacp Display status information about the specified aggregated Ethernet interface or redundant Ethernet interface. 0: EX9200 - AEs go down instantly, physical member interfaces remain up. Interface does not come up; Interface flapping. EDIT: From the Juniper side, the AE looks ok. 0 up up aenet --> ae0. 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. PR Number Synopsis Lag interfaces are showing down after upgradation from 18. 0 up down aenet --> ae1. 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. The hold timer enables interface damping by not advertising interface transitions until the hold timer duration has passed. Created 2016-05-25. To specify more than one tracing operation, include multiple flag statements. So i've been investigating issues on an interface where I see the following on the ae when I run "show interfaces extensive ae9" Input errors: Errors: 28182975, This is a QFX-5100 VC. 1 if you want to use AE interface's interfaces (EX Series switches) | Junos OS | Juniper Networks interfaces ae Learn about the issues fixed in this release for MX Series routers. ae0. You cannot have more than 64 AE interfaces on a single Virtual Chassis. 1X53-D47. -----MUTHU PANDII----- Note: The prefer-status-control-active statement can be configured with the status-control standby configuration to prevent the LACP MC-LAG system ID from reverting to the default LACP system ID on ICCP failure. To identify an interface that has flapped, perform the following steps: Run the following command to verify if the interface has flapped: show interfaces <interface-name> Example: Description. Every interface transition that occurs during the Thank You, Looks like ae11 link agg is down: ae11 up down . Learn about open issues in this release for MX Series routers. I am running into an issue where the output of "show lacp interfaces ae0" shows the following. The remaining statement is explained separately.
