There are various ways to enable event logging by RSVP:
- LSP Up/Down event - These are logged into syslog.
- Debug tracing - Use command "
debug mpls rsvp ..." to enable various debugs. These events are displayed onto the console/telnet session.
- LSP History - Each LSP maintains a history buffer of size 32 and stores thelast 32 events for that LSP. This is supported in 5.2 and onwards.
