LDP display commands
Comware provides abundant MPLS monitoring commands for monitoring states
of LSRs, LDP sessions, interfaces and peers. These commands are the powerful
debugging and diagnosing tools.
After accomplishing the configuration tasks described earlier, you can execute the
display command in any view to view the running state of LDP and thus to
evaluate the effect of the configurations.
Table 520 Display LDP
Operation
Display LDP information
Display buffer information for LDP
Display LDP-enabled interface information
Display LDP saved label information
Display information on all peers of LDP session
Display information of the remote-peers in the LDP sessions
Display states and parameters of LDP sessions
LDP debugging commands
Execute debugging command in user view for the debugging of various
messages related to LDP
