Hi, Usually its like, if layer 3 is perfect then layer2 is assumed to be working fine. Now if you specifically want to test layer 2 only. Then, if its a P2P link, then you can only observe it for input errors, frames discarded etc.

Hi,
You can use "Show cdp neighbor details" to perform L2 tests.
Hope This Helps

hi, yes it's a good idea, but i'm sure that we can use a loop to do this test, thanks

Hi,
you can also configure a point-to-point connection between both routers and assign ip addresses, This prove L2 and L3 connectivity. You may wish to use /30 so only these two routers are able to talk to each other via the required interfaces.

If you have the same WAN encapsulation on the interfaces you can run #debug interface serial
this should give you a myseq/mineseen/yourseen seq number for layer 2 transmissions.
