Conﬁguring Trap Reporting

You can add new trap reporting destination conﬁgurations or you can modify an existing conﬁguration. You can deﬁne up to ten destination addresses and the set of traps that are sent to each destination address.

To add a new trap reporting destination conﬁguration or modify a current one:

1From the top level of the Administration Console, enter:

snmp trap addModify

The system prompts you for a trap destination address, that is, the IP address of the SNMP manager that will receive the traps.

2Enter an IP address of the SNMP manager (destination address) .
