8.1.5.2.2 Configuration of Trusted Managers via SNMP
To configure Trusted Managers, the EM must use the srCommunityMIB, the
snmpTargetMIB and the TGT-ADDRESS-MASK-MIB.
To add the first Trusted Manager, take these 3 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, 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 done
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 done
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 affect immediately. The deleted trusted manager cannot access the
board. The agent automatically removes the row in the tgtAddressMaskTable.
