working on my final project and I can't get cisco works to pick up any devices, does anyone have experience with it? so far I've verified that cdp is on and working, both cisco works and the routers are using snmp version 2c, the community strings are the same on both ends. I have set the snmp host address on the routers, sending both traps and informs and they're all using udp port 162. The server running ciscoworks is able to ping all the routers.
I'm honestly 100% lost here, both me and my instructor have been working on it and we're not having any luck. any ideas?
trying to get it to talk to 2811's for now, if it matters.

Make sure there is no firewall in the way. Look at the snmp counters on the routers/switches to see if it's receiving the SNMP GETs. Other than that the most common is mismatched community strings, or possibly an access list specified on the router for snmp to restrict it to certain hosts. For example snmp-server community mycomm string RW 120, that says only accept SNMP from ACL 120.
Most times with ciscoworks you can add a seed device and run discovery from there. Also double check all device credentials, you can run a report to see what devices aren't able to be fully managed and what credentials are wrong.

thanks for the response spidey, I'll check it out after lunch. I know the credentials/community strings are ok on both sides, but how do I check the snmp counters on the routers? I tried to 'debug snmp packets' and didn't get anything. There are no ALC's on any of the routers yet, they're very basic want to get everything working then I'll throw the ACL's up.

Show snmp will give you the counters. Debugging would be even better, just remember to be careful with it - like don't do any debugging where you would expect a ton of messages.
Debug and other messages by default won't be sent to terminal lines (vty - your telnet). Turn on terminal monitoring to see any debugs with command "term mon"
there is my show snmp, looks rather slim for running for a few hours but I'm not sure what I'm looking for, or show much.
I didn't even think about debug messages not being sent over vty but still not getting anything there... I'll give it a while since it looks like only 8 snmp packets have been sent in the last few hours..

so, if I manually enter the devices it works, or seems to work. I just had to manually enter the user names/passwords as well as the ip and both community stings. Seems like for 6k+ they would have a product that would at least discover their own devices...
