To trace the creation of and changes to Layer 2 circuits, include the traceoptions statement:
traceoptions {file filename <files number> <size size> <world-readable | no-world-readable>;flag flag <flag-modifier> <disable>;}
You can include this statement at the following hierarchy levels:
- [edit protocols l2circuit]
- [edit logical-systems logical-system-name protocols l2circuit]
Specify the following flags to trace the indicated operations on Layer 2 circuits:
- connections—Layer 2 circuit connections (events and state changes)
- error—Error conditions
- FEC—Layer 2 circuit advertisements received or sent using LDP
- topology—Layer 2 circuit topology changes caused by reconfiguration or advertisements received from other PE routers
