The Network Devices page is a catalog of routers that APM encounters during diagnostic testing. When APM returns its hop-by-hop analysis, you can choose to save routers of interest for SNMP polling. You can also add to this list of network devices from the Network Devices page.

Initiate an SNMP walk

APM has access to an extensive SNMP MIB library, that covers commons vendors like: Alcatel, Broadcom, Avaya, Cisco, IBM, Lucent, Nortel, Xerox, etc. With access to this library, APM can automatically determine which MIBs are available on a device, and then walk each one. The results are organized in a hierarchical tree that you can walk manually or search. OIDs that can’t be matched to a MIB are grouped under ‘unknown OIDs’; and if the device doesn’t return a value for MIB, it is hidden by default.

To initiate an SNMP walk on a network device:

  1. Navigate to Delivery > Network Devices.
  2. Click the row containing the network device you are interested in
    • The network device details page is displayed.
  3. Select the SNMP Walk tab.
    • The device is polled for SNMP MIBs and associated information.
    • You can refresh the list at any time using the Refresh button.
