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.

Release	Modification
12.3(7)T	This feature was introduced.
Cisco IOS XE Release 2.1	This feature was introduced on Cisco ASR 1000 Series Routers.

How to Troubleshoot Multilink PPP over ATM LFI

This section contains the following procedure:

•Troubleshooting Multilink PPP over ATM LFI

Troubleshooting Multilink PPP over ATM LFI

Perform this task to display information about multilink PPP over ATM LFI connections.

Prerequisites

This task assumes that you have configured multilink PPP over ATM LFI in your network. For information about how to configure multilink PPP over ATM LFI, see the "Additional References" section.

SUMMARY STEPS

1. enable

2. show atm pvc vpi/vci

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	Displays traffic, management, and MLP over ATM LFI information for the specified PVC.
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	Displays MLP over ATM LFI debug information.

Examples

See the show atm pvc, show ppp multilink, show interfaces virtual-access, and debug atm lfi command pages for examples of output and descriptions of the fields in the output. For information about where to find the command pages for these commands, see Command Reference.
