You can use the following commands:
show log counters STP.OutBPDU occurred
show log counters STP.InBPDU occurred
"clear counter" will reset these values as well.
X480-24x.38 # show log counters STP.OutBPDU occurred
Component SubComponent Condition Severity Occurred I
----------- ------------ ----------------------- ------------- -------- -
STP OutBPDU Dump Debug-Data 1 N
STP OutBPDU Trace Debug-Verbose 2 N
This will give you a hint if the STP BPDU's are sent/received.
If you want you can then decide to add these to your log filter to display
these packets/events in greater detail to your log/syslog.
