Verifying and Monitoring Link Fragmentation and Interleaving

The Cisco 10000 series routers collect information about the number of:
•
•
•
•
The PRE1 counts only output fragments while the PRE2 counts both fragments and packets.
To verify and monitor the configuration of link fragmentation and interleaving, enter the following
commands in privileged EXEC mode:
Command
Router# debug atm lfi
Router# debug frame-relay fragment
Router# debug frame-relay ppp
Router# debug ppp multilink events
Router# debug ppp multilink fragments
Router# show atm pvc
OL-7433-09
Fragments and bytes sent
Unfragmented packets and bytes sent and received
Assembled packets and bytes received
Received fragments and bytes dropped due to excessive size of coalesced packets, out-of-sequence
arrival, duplicate sequence numbers, unexpected begin fragment, or arrival without a begin fragment
Verifying and Monitoring Link Fragmentation and Interleaving
Purpose
Displays debug information for MLP over ATM-based LFI.
Displays information related to Frame Relay fragmentation on a
PVC.
Displays error messages for link states and Local Management
Interface (LMI) status changes for PPP over Frame Relay
sessions.
Displays information about events affecting multilink groups
established for Bandwidth Allocation Control Protocol (BACP).
Displays information about individual multilink fragments and
important multilink events.
This command has memory overhead and should not be
Note
used when memory is scarce or when traffic is very high.
Displays all ATM permanent virtual connections (PVCs) and
traffic information.
