An alternative to the above procedure is to set the tgtAddressMask column while you are
creating other rows in the table.
The following procedure assumes that there is at least one configured read-write community.
There are currently two or more Trusted Managers. The taglist for columns for all rows in the
srCommunityTable are currently set to MGR. This procedure must be performed from one of
the existing trusted managers, but not the one that is being deleted.
To delete a Trusted Manager (not the final one), follow this step:
Remove the appropriate row from the snmpTargetAddrTable.
The change takes effect immediately. The deleted trusted manager cannot access the
device. The agent automatically removes the row in the tgtAddressMaskTable.

SNMP Ports

The SNMP Request Port is 161 and the Trap Port is 162. These ports can be changed by
setting parameters in the device ini file. The parameter name is:
SNMPPort = <port_number>
Valid UDP port number; default = 161
This parameter specifies the port number for SNMP requests and responses. Usually, it
should not be specified. Use the default.

Multiple SNMP Trap Destinations

An agent can send traps to up to five managers. For each manager, set the managers IP
address, receiving port number and enable sending traps to that manager.
The user also has the option of associating a trap destination with a specific SNMPv3 USM
user. Traps are then sent to that trap destination using the SNMPv3 format and the
authentication and privacy protocol configured for that user.
