Massive Infrastructure

I work in an ISP and are so many networking devices. Mostly Cisco. I am wondering on how can I find out for how long the device was up or basically when it was last rebooted.

If I have around 100+. I cannot just go in each and use the show version command?. And that too for every 2 days. That almost not possible.

Is there a way out form this?


Re: Massive Infrastructure

Give this a try with snmp:

server:/home/xxx> snmpwalk -v2c -c public sysUpTime

EXPRESSION-MIB::sysUpTimeInstance = Timeticks: (78915880) 9 days, 3:12:38.80

The time (in hundredths of a second) since the network management portion of the system was last re-initialized.

Re: Massive Infrastructure

you mean by using snmp queries. Therefore I will have to enable Read Only community on the server.

If my server is Linux Based then the command

server:/home/xxx> snmpwalk -v2c -c public sysUpTime

is on the Linux Server?

I am not familiar with the above commands. Please explain on what it does?


Re: Massive Infrastructure

The Read Only community needs to be configured on the routers and switches (in the previous example the comunity string is set to public)

The snmpwalk is performed on the linux server.

If you do not have snmp utilities, you may download them from
