PowerConnect 8024F: show debug messages on telnet session
Hello all,
can someone give me a hint on how to enable debug messages in a telnet session on a PowerConnect 8024F switch?
I configured 'logging monitor debugging' and then set 'terminal monitor' in the session. After a 'debug spanning-tree bpdu', lots of messages should appear, but they don't. The first lines of 'show logging' are:
Logging is enabled
Console Logging: Level warnings. Messages : 247 logged, 6349225 ignored
Monitor Logging: Level debugging. Messages : 2392176 logged, 3947464 ignored
Buffer Logging: Level informational. Messages : 208261 logged, 6141546 ignored
File Logging: Level emergencies. Messages : 0 logged, 6349822 ignored
Switch Auditing : enabled
CLI Command Logging: disabled
Web Session Logging : disabled
SNMP Set Command Logging : disabled
Logging facility level : local7
Syslog Server Details:
xxx.xxx.xxx.xxx : Level informational. Messages : 601 dropped
16052 Messages dropped due to lack of resources
Buffer Log:
...
Software version is 5.1.10.1.
Thanks,
Robin

Hi Daniel,
you are right, the debug messages do show on a second telnet session! Weird, but appropriate for now.
I am after these messages, occuring exactly every minute:

My first thoughts were to see if some debug output (debug isdp) would show some details. But nothing.
Any hint on where to look?
Thanks,
Robin

Directly connected is a PowerConnect 5548 switch. That switch itself has a few more PowerConnect 5548 connected, so there is a little tree of switches on Port Te2/0/9.
I will further investigate tomorrow.
