ccmCommonUserTable
Cisco Common User Table
1.3.6.1.4.1.9.9.443.1.1.5
This table lists all the common users configured on this device. A common user is a user who is common across SNMP, CLI and other device access methods. Certain access methods might need the user created to be standard compliant. For example - for SNMP, the user created need to be compliant to RFC 3414 (SNMP-USER-BASED-SM-MIB). When a common user is created in this table, a corresponding SNMP user is created in the 'usmUserTable' with corresponding instance of usmUserStorageType set to readOnly . Similarly when a common user is deleted from this table, the corresponding entry in the 'usmUserTable' is deleted.
