My new 2950 switch haged when in work after mins! I think that the problem is about it's CPU cooling, how can I check cpu current temprature and compair it with normal range?
thank you.

use the commans Show environment cooling command.it shows the room temperature. Virtual Exec process is responsible for the vty lines (telnet sessions). And the most common reason for the high CPU utlization in the virtual exec is transferring too much data.

Unfortunately, in these small layer-2 switches there is not much environmental monitoring. But I think there must be some way to trace your problem. Have you left a terminal attached to the console port at the time of the hang, and what was that last thing it said?
If you think it is a temperature issue, when it hangs, reboot it. If it really is a temperature issue, then it would probably hang again almost immediately. If it takes the same time to hang from a hot restart as from a cold one, then it is probably not temerature related.
In my experience, hanging problems are often due to memory pool exhaustion due to some bug. Try show mem at hourly intervals and see if the buffer pools are going down.
