Link-Flap Detection Syslog Messages
If you've configured link-flap detection to send log messages,
the following messages are sent after excessive flapping:
- If the threshold is exceeded, and the log action is set, and the disable
port action is not set, then a log message similar to the following
appears:
03/31/2016 15:56:36.52 <Noti:vlan.msgs.PortLinkFlapActLogEvent> Port 1 link-flap detection operational status is UP. Link has flapped more than 3 times in 60 seconds.
- If the log action and disable port action are set, and the threshold is
exceeded, then a log message similar to the following
appears:
03/31/2016 15:51:13.61 <Noti:vlan.msgs.PortLinkFlapActLogEvent> Port 2 link-flap detection operational status is DOWN. Link has flapped more than 3 times in 60 seconds.
-
This log message appears when all of the following conditions are met:
- Disable port action is set on a port.
- The number of link-flaps on the port exceeds the threshold.
- You issue the command enable
log debug-mode.
- You add the event to the log filter (for example: "conf log filter
"DefaultFilter" add events vlan.msgs.PortLinkFlapActDsblPort")
03/31/2016 15:51:13.61 <Summ:vlan.msgs.PortLinkFlapActDsblPort> Port 2 is disabled for excessive link flapping. Link has flapped more than 3 times in 60 seconds.
