Hi, My cisco router sends a lot FAN messages, that its buffer gets full and i lose important messages.

is there any way i can instruct router not to capture FAN related messages in buffer some how?

You might be able to use the logging filter command along with a TCL script.

But seriously, you should get the root cause taken care of - get the fan fixed or RMA the router. If you are really concern about important message, you should use a syslog server. Logging buffer will not store any data if the router is rebooted.

I dont know Jerry..... These fans are noisy, cause syslog messages and consume power. Who needs them!!! I'll give ya 5 points for the effort though.
