Hi All,
Please figure me for my stupidity but i do not have a clue when it comes to routers.

We have a Cisco router 7204. I am trying to figure out if SNMP is up and working. I have a perl script that will query the router but when run the script, I do not receive a response from the router.

How can I tell if SNMP is working?  Do I need exec "snmp-server manager" to be able to poll the router? How can I list the communities?

Thanks,
Angelmoon

PS
show snmp command displayes the following info:
Chassis: 31412513
902800 SNMP packets input
    0 Bad SNMP version errors
    1592 Unknown community name
    0 Illegal operation for community name supplied

    0 Number of altered variables
    646006 Get-request PDUs
    255187 Get-next PDUs
    0 Set-request PDUs

From the router, use the following command:

router#show run | include snmp

If you see something like this:

  snmp-server community <community> RO
  snmp-server community <community> RW

Then the server is running, and the community strings will be what you will need to program into your perl script..

> 1592 Unknown community name
Tells me that you might be trying to use the incorrect community name in your script...

You have to be in enable mode.
Does your prompt look like:

Usermode:
router>

or
Enable mode:
router#
