How Do I Restrict Monitoring to SNMP Traps for a Device?
You want to keep the network management traffic against a particular
device on your network to an absolute minimum, but still want to allow
the device to inform you of unusual events.

select it.
2 Select the Device > Properties menu option to launch the Properties
dialog box.
3 Select the Monitoring tab.

Key Considerations
The following section provides assistance when working with device
properties.
Troubleshooting Some advice on errors that may occur on the system is given below:
There Is No Port Information For My Device
The Properties dialog box for the device you selected does not show a
tree on the left-hand side, so it is not possible to view the properties of
individual ports on that device.
The most likely reason for this is that 3Com Network Director does not
support the device. For devices that are not supported by 3Com Network
Director, neither unit or port information can be extracted, so no
properties can be viewed for either a unit or a port on that device. Ensure
that 3Com Network Director supports the device.
