snmp_cisco_info
A script that presents information about Cisco devices using SNMP.
Suitable to use as a plugin for any Nagios compatible monitoring system.
The script utputs a string with:
>hostname,
model,
IOS version,
serial nr.,
location,
contact"
All the fields are queried by SNMP from the device.
The location field is whatever is configured with "snmp-server location" in running-config on the device.
The contact field is whatever is configured with "snmp-server contact".
The formatting of the output string can easily be modified at the top of the script. The string can then be used by some external system or just as information as is. It is for example possible to query the API in Op5 Monitor for the information gathered by this plugin. Logical devices in a stack or cluster configuration will output one row of information per physical device.
This script was wtitten for OP5 Monitor in order to populate a database for device inventory consisting of more than 2000 Cisco network devices. It has been tested with with: 6500, ASR and other routers, different Catalyst, Nexus...

USAGE
