Summary
There are three aspects of troubleshooting frame relay:
troubleshooting the link, troubleshooting the mapping from one
router to another, and troubleshooting routing across a frame
relay network.
Use the show interface serial and show frame-relay lmi
commands to verify Layer 1 and Layer 2 link failures. Use the
show frame-relay map and show frame-relay pvc commands
to test connectivity between routers.
