After switch migration, mlag keeps showing peering, how should I fix it?

After the migration of two switches that normally run mlag, all the service interfaces of the standby switch are Down, and checking the mlag status shows peering. How can I fix it?

Hello!

Can you try to remove then re-add the IPL link and see if that helps:

  • no interface ethernet 1/x channel-group
  • no interface port-channel 1

Then add the configuration for IPL and member interfaces back into the port-channel.
If this does not help, please open a case with support team for further investigation.
