Step 5 Select Network Connectivity: Poll Node.

Task 7—Using HP OpenView to Create the SNMP Framework

About SNMP Demand Polls

Map color legend:

•Green—The device is up.

•Yellow—Multiple interfaces are down.

•Light blue—One interface is down.

•Dark blue—The device is detected, but it has never been managed. The device is unreachable.

•Red—The device is down and unreachable.

Step 3 Select a device icon in the map (single click).

Step 4 Go to Fault.

Step 5 Select Network Connectivity: Poll Node.

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		Indicates SNMP is working and the system identifier for the device
to .1.3.6.1.4.1.9.1.162		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.

Supported versions		Describes which versions of SNMP are supported by HPOV, such as
		SNMPv1 and SNMPv2C.

Verify node name		Verifies the node name is valid.
