Tracing LMP Traffic

To trace LMP protocol traffic, include the traceoptions statement at the [edit protocols link-management] hierarchy level:

[edit protocols link-management]traceoptions {file filename <files number> <size size> <world-readable | no-world-readable>;flag flag <flag-modifier> <disable>; }

Use the file statement to specify the name of the file that receives the output of the tracing operation. All files are placed in the directory /var/log.

The following trace flags display the operations associated with the sending and receiving of various LMP messages:

all—Trace all available operations
hello-packets—Trace hello packets on any LMP control channel
init—Output from the initialization messages
packets—Trace all packets other than hello packets on any LMP control channel
parse—Operation of the parser
process—Operation of the general configuration
route-socket—Operation of route socket events
routing—Operation of the routing protocols
server—Server processing operations
show—Servicing operations for show commands
state—Trace state transitions of the LMP control channels and traffic engineering links

Each flag can carry one or more of the following flag modifiers:

detail—Provide detailed trace information
receive—Packets being received
send—Packets being transmitted
