I am relatively new to OID's and MIB's and am looking for a little bit of advice please.
Basically, I want to monitor the output of the top line of a "sh int s0/0",
serial0/0 is up, line protocol is up
I am looking to monitor this command to see when a leeased line fails. I have an application which will test the OID at regular intervals but I cant find the right OID to use. The router I want to use it with is a 2620XM.
Can anyone point me in the right direction and is what I am asking possible ?
Will a line failure actual show in an OID and then trigger an alert, has anyone done this before ?
You could monitor those values directly, but assuming you have Syslog and SNMP traps enabled you SHOULD get messages about the interface going down - unless that's the interface you're monitoring through. :)
A bit more advanced process would be to use RMON Alarm & Event to have the device 'self-monitor' and throw an SNMP trap when the values change passed a threshold you set.
