are currently empty).
1. Add a row to the snmpTargetAddrTable with these values: Name=mgr0, TagList=MGR,
Params=v2cparams.
2. Add a row to the tgtAddressMaskTable table with these values: Name=mgr0,
tgtAddressMask=255.255.255.255:0. The agent doesn’t allow creation of a row in this table
unless a corresponding row exists in the snmpTargetAddrTable.
3. Set the value of the TransportLabel field on each non-TrapGroup row in the
srCommunityTable to MGR.
To add a subsequent Trusted Manager, take these 2 steps:
(The following procedure assumes that there is at least one configured read-write community.
There are currently one 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).
1. Add a row to the snmpTargetAddrTable with these values: Name=mgrN, TagList=MGR,
Params=v2cparams, where N is an unused number between 0 and 4.
2. Add a row to the tgtAddressMaskTable table with these values: Name=mgrN,
tgtAddressMask=255.255.255.255:0.
An alternative to the above procedure is to set the tgtAddressMask column while you are
creating other rows in the table.
To delete a Trusted Manager (not the final one), take this step:
(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.
• 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.
To delete the final Trusted Manager, take these 2 steps:
(The following procedure assumes that there is at least one configured read-write community.
There is currently only one Trusted Manager. The taglist for columns for all rows in the
srCommunityTable are currently set to MGR. This procedure must be performed from the final
Trusted Manager.
1. Set the value of the TransportLabel field on each row in the srCommunityTable to the empty
string.
2. Remove the appropriate row from the snmpTargetAddrTable
The change takes effect immediately. All managers can now access the device.
11.6.3 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.
