Usage AlliedWare Plus™ provides other kinds of logging services for neighbor status, for
example, debug bgp fsm and debug bgp events.
However, these commands create a significant hit in the logging performance. If
you need to log neighbor status changes only, we recommend turning off all the
debug commands, and then use this command.
To see BGP neighbor changes in the log you must also set the log level to
informational using the log buffered command.
A sample output of this log is:
