How would one go about changing the encapsulation on an Ethernet switch
interface. I only have a 2900 and can find an encapsulation command under
the interface. Am I missing something here? I know this trick works for
serial interfaces but what other encapsulations do you get for Ethernet
interfaces?
TIA

If you just want to test the backup interface, why don't you encapsulate the
interface with another type, I am sure this will bring down the
interface...Becky
