Hello
I'm doing EVC and QinQ testing with ME3600, Cat3560 and some Routers.
Refer to the uploaded test diagram, found "%SW_MATM-4-MACFLAP_NOTIF: Host 0021.a06a.488c in vlan 500 is flapping between port Fa0/11 and port Fa0/16" keeps appearing in the console.
At the beginning, R1 can ping R3 and R4, and R2 also can ping R3 and R4. But after few minutes, they no longer can ping each other.
I tried to disable l2protocol-tunnel stp, R1 can resume ping to R3 and R4 now but it cannot ping in first 2-3 packets at the beginning then resume and after around 1000 pings, it will have 2-3 packet loss and resume again.
Also, the vlan flapping of s-tag 500 still appeared at SW1. I have tried to disable the spanning tree on vlan 500 but problem still exists
Config files will also be uploaded.
Could anyone help? Thanks!
