Layer 2 troubleshooting on switch

[siddiqirf]

I am troubleshooting a Dot1q Layer EoMPLS solution with the service provider which is faililng to work. Are there any good cisco debug commands I can use for Layer 2 troubleshooting on the cisco switch so that I can go back to the service provider with some concrete evidence or is packet capture the best way ?

Unfortunately, i am not the service provider, but the end customer. EoMPLS is running in the ISP core, of which I have no visibility.

I was hoping I could do some Layer 2 troubleshooting on my cpe switches to proof to the ISP that layer 2 is not working end to end i.e. from my cpe in site A to my cpe in site B

Hi,

some useful debugs that i would use for L2 troubleshooting,

--debug arp (will enable us to check whether are we getting the arp replies from the other side)

if you want to set some condition where this debug has to run you can do that by,

debug ip po1

Hope this helps

Cheers
