Observing Random Mac move in the network on QFX5100

  • 1.  Observing Random Mac move in the network on QFX5100

    Posted 03-23-2023 09:02

    Hi,

    We have a Core configured in VC of 2 members (QFX5100 96s) and all the Access switches are EX4300 with two uplink to core which are configured as AE.

    From yesterday i am seeing a MAC move on many siwtches, corss checked for rstp configuration its all fine and we looked  L2 loop not able to find anything na dno flood in the network.

    One way we found to stop MAC move on one switch is the disable one UPlink to the core which is in AE if this is done then there wil be no MAC move in that particular access switch and we have repeated this on the switches whcih we were facing issue for a temp fix .

    Thing i found strange was the license issue on the core where i have attached the logs below can someone guide me what this alarams refer to is the above issue might be because of this and  if so how can we fix it.
