306 CHAPTER 7: MONITORING THE NETWORK
3Com Network Director will not register itself as an SNMP trap
destination with non-3Com devices when you start monitoring them, nor
will it de-register itself when you stop monitoring them.
If you wish 3Com Network Director to receive traps from a non-3Com
device then you will need to manually add the IP address of the PC that
3Com Network Director is running on to the trap destination table of that
device.
Similarly, if you no longer wish 3Com Network Director to receive traps
from a non-3Com device then you will need to manually remove the IP
address of the PC that 3Com Network Director is running on from the
trap destination table of that device.
Please refer to the device’s own user guide for details on how to do this.
