Hi, I am new to the Mellanox Switch. I am going to configured MLAG for SN2010.
I found that the port-channel for MLAG is up and “Operational Status : UP” from show mlag. But these two switch seems cannot form cluster ( no master and slave status). There is no result from show mlag-vip as well. Is there anything missing? Thanks
mgmt0 port is up?
No, mgmt0 is down. I haven’t configured anything on mgmt0 port!!
Current physical connection
Core_SW01 eth1/21-1/22 <-> Core_SW02 eth1/21-1/22 (IPL)
Core_SW01 eth1/1-eth1/2 & Core_SW02 eth1/1-eth1/2 (MLAG interface to Access-layer SW)
Is it necessary to have connection at mgmt0 interface between Core_SW01 and Core_SW02?
The cluster status is based on the vip connection that runs across the mgmt0 ports.
As shown in this doc (https://docs.mellanox.com/display/Onyxv382306/MLAG), it is expected for the cluster to be unknown if this connection is down:
“”"
In a scenario where there is no IP communication between the MGMT ports of the MLAG switches (for example when one MGMT port is disconnected), the following CLI prompt is displayed: [:unknown]#. This does not reflect the MLAG state, but only the state of the cluster.
