Spectrum discovers and models device without any interfaces
Article ID: 101478
Once I discover a particular device, Spectrum models it without any interfaces. If I select the Interfaces tab I got "This model has no interface" message. Other devices are modeled correctly. The issue seems to happen for particular devices only.
There is no interface table, i.e. ifTable - 188.8.131.52.184.108.40.206.1 OID branch, in the device MIB database.
All Spectrum versions
To identify the problem collect SNMP walk of the device.
You can use sapwalk2.exe utility to collect SNMP walk. If you are running 10.2 or later the utility executable is in $SPECROOT/bin directory on the SpectroSERVER machine. If you are running older Spectrum version, this utility can be downloaded via ftp from ftp.ca.com in the /pub/CA-SPECTRUM/Tools/sapwalk2 directory. You can login as anonymous user with your email address as password to the ftp server.
The usage can be found by just running the sapwalk2 executable. However, a recommended usage is as follows:
Open generated SNMP walk file, e.g. device_mib.walk, using text editor and search for 220.127.116.11.18.104.22.168.1 OID. If you don't have it this means device's MIB database doesn't have interface table information and Spectrum won't be able to model interfaces.
You should work with device's Administrator or Vendor to configure or implement interface table in the MIB database.
