Hello all!
I have spent a lot of time, and i cannot bring up lacp bonding between two linux hosts or linux and cisco device.
Can anyone tell me please the right way?
I just achieved LACP pdu has sent every !!! 46 seconds on the ubuntu server! With lacp_rate=fast config.
Then i have tried centos-server without success at all, just periodic lacp frames captured, otherwise L3 bond work well in active/backup mode between two linux guests and ??? arp monitoring.
Anyone have ahieved working L2 LACP bond config on the linux guest?
Thanks in advance.

Re: Linux LACP bonding with qemu
+upd
Above tests was implemented on eve-ng community edition.
I have asked my colleagues about their experience, and they have infomed about success with LACP between Windows and N9Kv on EVE-NG pro eddition.
I will try LACP linux == N9Kv on pro edition and will update this post .

Re: Linux LACP bonding with qemu
I never did it on EVE Pro with Linux node on topology, but I can confirm that LACP from Winserver 2016 to Nexus vPC works fine

Now i'am trying to find a way to determine link failure on the server side.
(is seems thaty linux didn't shutdown the link while lacp pdu timeout)
ps may be the only way is to monitor with arp.
I have configured LACP bonding with linux server.

Now i'am trying to find a way to determine link failure on the server side.
(is seems thaty linux didn't shutdown the link while lacp pdu timeout)
ps may be the only way is to monitor with arp.
