Frame Relay Configuration 269
Using the debug frame-relay lmi command makes it possible to watch the real-time
communication between the router and the switch. Each request sent from the router to the
switch is noted as MySeq, and the counter is incremented by 1 with each request. LMIs sent
from the switch to the router by the telco are noted as Yourseen and also are incremented by 1
with each request. As long as both numbers are greater than 0, the router should be happy and
functioning normally at Layers 1 and 3. (Layer 3 connectivity is up to the administrator doing
the configuration.) You should also watch the "DTE up" note at the end of the outbound LMI
status lines.
show frame-relay map Command
The show frame-relay map command is used to view the DLCI mappings that have been
created. They can be static or dynamic and are noted as such in the command output.
Example 9-7 shows the output from this command.
