Hi all,
often i get mac address flap error in switches, but unable to identify the cause for some cases.
AS1---DS---AS2.
Two switches AS1 and AS2 are connected to DS and i am seeing host mac address connected to AS1 being learnt from AS2 connected port in DS under same vlan 100. There is no physical loop in this connectivity. While checking i found mac address aging timer higher in DS (480s) than in AS1(30s) and AS2(30s). Even when the host pc goes down it takes some time for the address to get flushed in DS mac table. Would this be causing this mac flap ?
