health check on cisco device

Normally, how people perform the health check on Cisco device? What kind of command will be use in order to see the error message or log from the console? For example: cisco switch 2950 or 2600?

Re: health check on cisco device

For switches, try the commands sh post and sh environment alarm.

For routers, look at the logs for the first sign or sometimes you can use sh diag.

A word of caution: When using the sh environment alarm on a 2940/2950 switch, if you don't have RPS but you see some display that the RPS is bad or faulty, just ignore this. I don't remember the specific IOS version but this is a known minor bug.

Hope this helps.

You may not understand much from the show diag if you are not used to cisco devices.

If you look at logs, then show log will do. You could log your log messages to a syslog or snmp server.

Go to configure logging:
