To add the first Trusted Manager, follow these steps:
(The following procedure assumes that there is at least one configured read-write
community. There are currently no Trusted Managers. The taglist for columns for all
srCommunityTable rows 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 does not 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, follow these 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), follow this steps:
(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, follow these 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.
