LACP interoperability with nexus 9000v

[Alain Degreffe]

Hi,

I'm facing a issue in lacp with nexus 9000v and vIOS

LACP doesn't work at all.

What I observe is that Nexus use destination mac address 00:01:02:03:04:05 for LACP packet.

On the RFC, this should be 01:80:c2:00:00:02 ( and that's the address used by other switches type )

Is this normal ?

Currently only Nexus can negociate LACP with Nexus.....

Just curious, trying to apply this fix to nxos.7.0.3.I7.3.bin N9Kv image and it does not work. For which N9Kv version in particular this  fix worked for you?

this is what I have at the moment:

N9Kv# show lacp counters
-----------------------------------------------------------------------
Port        Sent Recv Recv Sent Pkts Err
port-channel1
Ethernet1/1 1    0    0    0    0
Ethernet1/2 1    0    0    0    0

vIOSL2#show lacp counters
Port    Sent Recv Sent Recv Sent Recv Pkts Err
----------------------------------------------------------------
Channel group: 1
Gi0/0   4    1    0    0 0 0 0
Gi0/1   4    1    0    0 0 0 0

so, vIOSL2 actually can recognise LACP packets detined to 00:01:02:03:04:05 mac address, but N9Kv ignores LACP packets destined to 01:80:c2:00:00:02

Found this for nxos.7.0.3.I7.3.bin
https://0bin.net/paste/-5tCGc-U-6077INn#PxLYrgY8SosA5V1UMgnBYHWgnTfQj+9FzuIepi70a-G

it actually works:

N9Kv# show lacp counters
------------------------------------------------------------------

Port              Sent                Recv                  Recv Sent  Pkts Err
port-channel1
Ethernet1/1        8                    9                      0      0    0   
Ethernet1/2        8                    9                      0      0    0   

N9Kv# show int po 1
port-channel1 is up
N9Kv# show version
  NXOS: version 7.0(3)I7(3)
