Tool/script to get information (i.e. model/ios ver) from cisco switch

[kamil.swedrak]

Hello all,

I'm looking for a tool/script which will scan my 3 subnets in the network and will gather some basic information from cisco switches (i.e. model, ios ver). Do you know how to automate this task?

I can check/log in to each IP "active" IP address in the network but this is time consuming process.

Please advise how to automate this task (script will be awsome, but some IP scanner will be also very desired) - thank you.

P.s. Perfect output for me:
cisco 2960 | 12.4(25)

Best regards,

/KS

I would suggest trying the 'cisco active advisor' or use snmp to collect network inventory.

Otherwise, you can post your question in EMM scripting section.

Good luck!

Thanks engineer_aus for your reply and suggestion.

Cisco Active Advisor looks good, but I would like have this "functionality" without 3rd party software.

SNMP will be enough but don't know how to do that.

Question to you guys if you have any "ready" command which I can use to obtain this kind of information.

Thank you very much!

I have written a tool that will do host discovery and display SNMP information about each host discovered.   Host discovery uses NMAP to probe a subnet or subnets and writes IP addresses to a file that respond to ICMP.    Another script reads in the IP address file and polls each device with SNMP.   See attached for files.   Here is example output provided by the tool.
