cisco router 2611 interface uptime

[verilet]

hi i have a cisco 2611 router, and last night my network monitor program send me emails saying that the ping service to servers in a remote location where unreachable. So what i want to check, is when was the last time my interface went down. i know i can check the router uptime with sh ver, but is there a way to do it just for a specific interface? or is there another way i can troubleshoot my problem? my remote servers didn't go down but rather i think the t1 went down or somehting.

thanks,

hi

If you have the logging on you should be able to

see it in the log. You should see at what time the interface went down and again up. As soon as the router is reloaded the log will be cleared. The command is "show logging".

Hope that helps you

thanks rwiesman,

i get the follwing,

Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overru

Console logging: level debugging, 633 messages logged

Monitor logging: level debugging, 0 messages logged

Buffer logging: disabled

Trap logging: level informational, 635 message lines logged

and when i do sho logging history i get,

Syslog History Table:1 maximum table entries,

saving level warnings or higher

31 messages ignored, 0 dropped, 0 recursion drops

26 table entries flushed

SNMP notifications not enabled

entry number 27 : LINK-3-UPDOWN

Interface Serial0/0, changed state to up

timestamp: 112404665

does this actually mean the s0/0 changed states? how can i view the actual logs?

any help is appreciated,

thanks

hi

as i can see you do not have logging bufferd enabled on the router.

so configure the following:

logging buffered 64000

> enables logging to the router buffer

service timestamps log datetime

> gives you the timestamp of the log in the format

> dec 9 21:52:02

You also have to synchronise the time to an ntp server so you can see whene an event happened.

the info you trying to getter is probably not available anymore but now you are set for events in

the future.

hope that helps
