Verifying and Monitoring Link Fragmentation and Interleaving
The Cisco 10000 series routers collect information about the number of:
• 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
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 Purpose
Router# debug atm lfi
Displays debug information for MLP over ATM-based LFI.
Router# debug frame-relay fragment
Displays information related to Frame Relay fragmentation on a
PVC.
Router# debug frame-relay ppp
Displays error messages for link states and Local Management
Interface (LMI) status changes for PPP over Frame Relay
sessions.
Router# debug ppp multilink events
Displays information about events affecting multilink groups
established for Bandwidth Allocation Control Protocol (BACP).
Router# debug ppp multilink fragments
Displays information about individual multilink fragments and
important multilink events.
Note This command has memory overhead and should not be
used when memory is scarce or when traffic is very high.
Router# show atm pvc
Displays all ATM permanent virtual connections (PVCs) and
traffic information.
