HP Network Direr Software Products manual Monitoring Non-3Com Devices

Key Concepts 279

If an SNMP trap is received that does not have a monitor associated with it then 3Com Network Director will use the trap to generate an event directly.For more information see “The Event Log” on page 319

See “Registering 3Com Network Director as an SNMP Trap Destination” on page 304 for more information on controlling how 3Com Network Director registers itself with SNMP trap sources as an SNMP trap destination.

Monitor-able Items 3Com Network Director can monitor most devices and links that are displayed in the map, including:

■Network infrastructure devices

■Servers

■End stations

■NBX phones

■Ethernet links, including aggregated links

■WAN links

The particular attributes that can be monitored for a device or link depend upon the exact type of device or link that is being monitored.

Monitoring Non-3Com Devices

3Com Network Director will monitor most non-3Com network devices to some extent. However, as some non-3Com devices do not present their statistics in a standard manner, 3Com Network Director is unable to provide full monitoring support for non-3Com devices. In particular:

■3Com Network Director will not monitor features on non-3Com devices whose statistics are presented via proprietary mechanisms.

■3Com Network Director will not register or de-register itself as an SNMP trap destination with non-3Com devices.

Link Monitoring When you start monitoring for a link, 3Com Network Director starts monitoring for the devices at the ends of that link automatically.The monitors for the link then use the data gathered by one or both of the devices for the port(s) that the link connects to in order to provide the data that they require.For monitors which use only one device, the selection of which device to use as the data source for a link’s monitors is performed automatically, and is based upon which device provides the most detailed information about the link. The algorithm used is:
