    It simply doesn't discover their IP address as neighbors. The specific model number is WS-C3560-8PC. Just wondering if anyone else has had this issue.

      Can you provide me the debug output? Also, what happens if you rcdp the devices's IP address directly, does it work each time? If yes, it could actually be an issue with the upstream device.

      thanks,

    Marcus, thanks for the response... file is attached. First section is the normal run so you can see the output a little more clearly, then the same command with -d. Let me know what you think.

    Hello Marcus, just checking to see if you had a chance to look the logs over. Thank you in advance.

      Hey,

      Sorry I haven't had a chance to look at it yet. I will get to it this week and send out an update.

      thanks,

    No problem. I know how that goes. Let me know if you need any more data.

      Do the C3560-8PC devices always return NA for an IP, or do they sometimes
      return an real IP address?

      If you rcdp the C3560-8PC device directly, does it always return and IP
      address or will it fail also?

      Also, on our SNMP strings, put the RW string first, then a RO string as the
      order is important.

      thanks

    It seems that they do always return NA. When i point at them directly, they seem to be functional. I only have a read only string, so there is only 1 snmp community in that spot of the conf file.

    I just have a single r/o community in the file and also on the devices.

      Hi Kakisger,

      Sorry for the delay, I work this project on the side from my regular job. Can you try your discovery without the -l flag (ie -rq) and see if the IPs for your C3560-8PC show up?

      thanks,

      -marcus

       

      • Marcus Beaman

        Just to be more specific this could be an issue with the "-v" flag, so please try the "-rq" and if this works you can try the "-rlq" and also see if this works. This would still give you serials and uplink output.

        thanks,

        -marcus

    Hey Marcus, it seems to have the same result. What seems to be happening is that when the 3560 is discovered via CDP, it's IP is not being picked up... so then it gets put on the "SK NO IP" (skip no ip i think). So even when we do verbose, the IP is just not being parsed from that switch.

      I agree, rcdp grabs the ip address for the devices the same as doing a "sho
      cdp nei detail". If you run that on the upstream switches, do you see an
      IP address for the devices? If you do, then there is some disconnect in
      the CDP neighbors SNMP MIB for those devices. You could also verify the
      CDP configs are consistent on the devices "sho run | inc cdp", and/or
      remove the SNMP config from the upstream device and re-add it to see if
      this clears the MIBs up. Make sure any "cdp source interface" commands
      have IP addresses assigned to them (if the commands is applied).

      At some point I we could also setup a web conference to do some
      troubleshooting real time.

      thanks,

    All the cdp configs are pretty standard, we don't fiddle with them. Definitely open to a web conference... when would you have time?

    Tried that, no go sir.
