Overview

The Neighbor Map in Engineer's Toolset does not return Cisco Discovery Protocol (CDP) data.

Environment

Engineer's Toolset for Desktop 10.9 and later

Cause 

This occurs when the polling times out as both CDP and Link Layer Discovery Protocol (LLDP) data are polled in order to ma the connections.

Resolution

  1. Verify that the device supports the OIDs used by running an snmpwak on the device and confirming the OIDs below are listed:
    cdpCacheAddressType    1.3.6.1.4.1.9.9.23.1.2.1.1.3    
    cdpCacheAddress        1.3.6.1.4.1.9.9.23.1.2.1.1.4
    cdpCacheDeviceId    1.3.6.1.4.1.9.9.23.1.2.1.1.6
    cdpCacheDevicePort    1.3.6.1.4.1.9.9.23.1.2.1.1.7

    lldpRemManAddrIfSubtype    1.0.8802.1.1.2.1.4.2.1.3
    lldpRemManAddrIfId    1.0.8802.1.1.2.1.4.2.1.4
    lldpRemPortId        1.0.8802.1.1.2.1.4.1.1.7
    lldpRemPortDesc        1.0.8802.1.1.2.1.4.1.1.8
    lldpRemSysName        1.0.8802.1.1.2.1.4.1.1.9
    lldpRemChassisId    1.0.8802.1.1.2.1.4.1.1.5
  2. If the device supports the above OIDS and both protocols are selected in the Discovery Protocol for the map, adjust the global settings in Workspace Studio to increase the number of retries. Refer to Modifying Workspace Studio Settings.
