| Description | This table provides a mechanism to map a common
user represented by ccmCommonUserName to one or
more roles. These roles provide access control
policies for a principal. Note that all the roles
used in the this table have to be present in the
commonRoleTable of CISCO-COMMON-ROLES-MIB.
For Common User - Role assignments created in this
table, for SNMP user access, the corresponding
entries are created in the vacmSecurityToGroupTable
(of SNMP-VIEW-BASED-ACM-MIB) in line with View-based
Access Control Model (RFC3415) and
cvacmSecurityToGroupTable (of CISCO-SNMP-VACM-EXT-MIB)
to represent all the mappings. All such instances in
SNMP tables are created with corresponding StorageType
set to readOnly.
Note that it is not necessary to update this table if
the user-role mapping data is changed using
corresponding access methods. e.g., if the SNMPv3
user-group mapping using vacmSecurityToGroupTable
and cvacmSecurityToGroupTable is changed, it is not
necessary to reflect that change in this table. |
