Monitoring Specific LC-ATM Label-Switching Functions

show mpls atm-ldp bindingsRouter#

• Displays ATM LDP label information base (LIB)

show mpls atm-ldp capabilityRouter#

• Displays the LC-ATM capabilities of this label switch router (LSR) and peering LC-ATM LSRs

Several other commands display labels in ATM format.

Summary

• Cisco IOS commands used to monitor LC-ATM label-switching functions are similar to show mpls ldp commands.

• show mpls atm-ldp summary shows information about all entries in the label-binding database.

• show mpls atm-ldp bindings shows current label bindings.

• show mpls atm-ldp capability shows parameters that have been negotiated between two LSRs.

• Specific LC-ATM debug commands will not need to be used during normal operation.
