Syntax

Description

Log a message or send an SNMP trap whenever an LSP makes a transition from up to down, or vice versa, and whenever an LSP switches from one active path to another. Only the ingress router performs these operations.

Note:

System log messages for LSPs are generated by default. To disable the default logging of messages for LSPs, configure the no-syslog option under the log-updown statement.
