LACP doesn't work on Timos

Post by mkorn » Tue Apr 03, 2018 1:47 pm

Hello team
I wasn't able to get LACP up and running on Timos. Tried various combinations but unsuccessful.
Wireshark dump shows that packets are passing through the link(s).
Seems like it is general issue, not vendor-specific.
Did anyone was able to run LACP on other platforms?
Can provide any information needed.
Thank you for your help

Yes it works

Cisco: CSRv1000, vIOS L2, IOL switches, Nexus
Arista, vEOS switches
Juniper, vMX, vQFX

and interconnections between diff vendors.

Example lab below Cisco CSRv1000 with mulithomed LACP to Arista Switch (mLAG) and NXOS multihome LACP

Thank you for your feedback, Uldis.
Yes, it works. I found workaround: if you create LAG with different instance numbers on opposite side of the line it forces Hardware Address to be changed.
(lag-X on side A and lag-Y on side B)
I'm not sure why it helps, but one difference after changing LAG number is new Hardware address:

A:PE1>config>lag# /show lag 1 detail | match Addr
Configured Address : 02:01:ff:00:01:41 Lag-IfIndex : 1342177281
Hardware Address : 02:01:ff:00:01:41

*A:PE2>config>lag# /show lag 2 det | match Addr
Configured Address : 02:01:ff:00:01:42 Lag-IfIndex : 1342177282
Hardware Address : 02:01:ff:00:01:42
