no bgp log-neighbor-changes
Syntax
None
Default
Disabled.
Command Mode
Router configuration.
Usage Guideline
This command enables logging of both BGP resets and alternating status
changes to use for troubleshooting purposes.
Unexpected neighbor resets might indicate high error rates or high packet loss in
the network and should be investigated.
The neighbor status change messages are not tracked if the bgp log-neighbor-
changes command is not enabled. The exception to this is for a reset reason,
which is always available as output of the s
how ip bgp neighbors
and
show
bgp ipv6 neighbors
commands.
The logs for BGP neighbor changes will display on the console.
Example
This example shows how to enable logging of BGP neighbor changes for
autonomous system 65534:
Use the
show logging
buffer
command to display the log for the BGP neighbor
changes.
Switch(config)# router bgp 65534
Switch(config-router)# bgp log-neighbor-changes
