xSTP Syslog for BPDU Threshold

The xSTP syslog messages for BPDUs are created when CPU utilization is more than the ISSU threshold value and also, when the system receives more than a certain amount of xSTP BPDUs.

If the received xSTP BPDU count goes higher than a threshold value and also, if the CPU utilization is higher, we will log the syslog. Later, when this condition gets cleared, another syslog message is generated.

Syslog messages for xSTP are logged into the system to inform that the CPU utilization rate is higher than the normal value and the BPDU processing rate for a minute is higher than the threshold limit. Syslog messages are generated depending upon the received STP or PVST BPDUs.

The following are some of the examples of syslog messages.

The syslog message for BPDU threshold crossing and clearing looks like the following:

SYSLOG: <#> xSTP BPDU Threshold (1000 pps) reached

The following syslog is created when the condition gets cleared

SYSLOG: <#> xSTP BPDU Threshold condition cleared

The clear syslog message is:

SYSLOG: <#> xSTP BPDU Threshold condition cleared
