Troubleshooting Enhancements for Multilink PPP over ATM Link Fragmentation and Interleaving
The Troubleshooting Enhancements for Multilink PPP over ATM Link Fragmentation and Interleaving enhance the output of the show atm pvc, show multilink ppp, and show interfaces virtual-access commands to display multilink PPP (MLP) over ATM link fragmentation and interleaving (LFI) information. This feature also introduces the debug atm lfi command, which can be used to display MLP over ATM LFI debugging information.

3. show ppp multilink [active | inactive | interface bundle-interface | [username name] [endpoint endpoint]]
4. show interfaces virtual-access [type number]
5. debug atm lfi
DETAILED STEPS
|
Command or Action
|
Purpose
|
Step 1
|
enable
Example:
Router> enable
|
Enables privileged EXEC mode.
•Enter your password if prompted.
|
Step 2
|
show atm pvc vpi/vci
Example:
Router# show atm pvc 15/200
|

|
Step 3
|
show ppp multilink [active | inactive |
interface bundle-interface | [username name]
[endpoint endpoint]]
Example:
Router# show ppp multilink username blue
|
Displays bundle information for MLP bundles.
|
Step 4
|
show interfaces virtual-access number
Example:
Router# show interfaces virtual-access 3
|
Displays status, traffic data, and configuration information about a specified virtual access interface.
•Display will indicate if the interface is a member of a multilink PPP bundle.
|
Step 5
|
debug atm lfi
Example:
Router# debug atm lfi
|
