Figure 28 SNMP Walk-Polling Results
Demand polls enable HPOV to:
•
Detect the sysobjectID (vendor ID) for each Cisco device.
•
Associate MIBs with each device.
•
Collect interface information.
Table 31 Important Fields to Inspect In the Polling Results
Field Description
Changing SNMP sysobjectID
to .1.3.6.1.4.1.9.1.162
Indicates SNMP is working and the system identifier for the device
was found. This field appears only the first time a device is
successfully polled.
HPOV changes a generic router icon into a Cisco device icon after
the sysobjectID is found. The trailing number series, for example
.1.3.6.1.4.1.9.1.162, is the OID that identifies a node as a
Cisco device.
