Alarm Information


Handling Process

This is NE80 BGP neighbor alarm information, which is trap sent to NMS
The possible reasons are:

If we only configure BGP neighbor locally, while the peer couldn`t be contact; or the normal BGP neighbor interrupts.BGP will try to re-establish its neighbor, if fails, the alarms will be printed out.


1.remove the unwanted BGP neighbor.
2.if it is normal BGP neighbor, check the reason of BGP neighbor interruption.
