48 Asynchronous Transfer Mode Interface Processor (AIP) Installation and Configuration
Using the Debug ATM Commands
Note
For SONET, E3, or DS3 interfaces, at least one of the AIPs must be configured to supply its
internal clock to the line.
Following is an example of configuration file commands for two routers connected through their
SONET, E3, or DS3 interfaces:
First router:
interface ATM3/0
ip address 1.0.0.1 255.0.0.0
no keepalive
map-group atm-in
atm clock internal
atm rate-queue 2 34
atm pvc 1 1 5 aal5snap
!
map-list atm-in
ip 1.0.0.2 atm-vc 1 broadcast
Second router:
interface ATM3/0
ip address 1.0.0.2 255.0.0.0
no keepalive
map-group atm-in
atm clock internal
atm rate-queue 2 34
atm pvc 1 1 5 aal5snap
!
map-list atm-in
ip 1.0.0.1 atm-vc 1 broadcast
Using the Debug ATM Commands
You can use the following debug commands to aid in solving ATM network problems:
•
Use the debug atm packet command to display the contents of the SNAP/NLPID/SMDS header
followed by the first 40 bytes of a packet in hexadecimal format.
•
Use the debug atm errors command to display information from all detected ATM errors. This
includes such errors as encapsulation failures and errors during ATM configuration.
•
Use the debug atm events command to display event changes to the AIP. Reset, VC
configurations, AIP configurations, and PLIM failures are displayed here.
Note
For a list of ATM error messages associated with the debug atm events command, refer to
the section “Interpreting ATM Error Messages,” which follows.
•
Use the debug atm oam command to display the contents of OAM cells as they arrive from the
network.
After you use a debug command, turn off debugging with the no debug command.
