ANI Discovery problem

I seem to have killed Discovery. I went into Campus Manager and deleted all of the devices but now D won't find any of my switches! I have a Cat6500 as my seed and it is the core of my switched network; everything else is a Catalyst 2900XL/3500XL. All have the same public/private SNMP community strings and the same Telnet and Enable Secret passwords. My Discovery settings have the 6509 as the seed and the SNMP settings are *.*.*.*:aaaaaaaa::10:2:::bbbbbbbb

Discovery finds the seed device but says that it is unreachable. I've gone to the device and done a "sh cdp neighbor" and can see all the attached devices; I've checked SNMP connectivity from CW2K. I've shut down and restarted the services on my server, yadda, yadda, yadda. One thing I'm curious about - are there restrictions as to the use of special characters (@!~$, etc) in SNMP strings?

OBTW - This is CW2K LMS 1.1 on WinNT 4.0 Server SP5.

Re: ANI Discovery problem

You may want to do a reinitdb to start with a fresh database (Note: using the reinitdb will delete all data in the Campus database which cannot be recovered back). Also refer to: http://www.cisco.com/warp/public/477/Campus/ani.shtml can go over the checklist to see if it helps.

Re: ANI Discovery problem

Sorry, should have mentioned that I tried a reinitdb. Didn't help. I don't seem to have any of the really obvious problems, that's why I asked about special characters in the community string. I've seen that the CatOS doesn't like @ signs....

Re: ANI Discovery problem

Yes, for CatOS @ is reserver for Community String Indexing:

So, if you're using @ in your strings for CatOS, try changing it to something else and then do a re-discovery to see if helps.

Re: ANI Discovery problem

Well, I had already taken the @ out but still had a tilde (~) in; apparently SNMP doesn't like special characters. I changed to all alphanumerics and things started working again.

Re: ANI Discovery problem

We tested and found these characters can be used as community strings in cw2k LMS 2.0 and 2.1 { $ * } /ee
