CHAPTER2 SNMP Overview
Mediant 800 SBC | SNMP Reference Guide
■ The user v3admin2 is setup for a security level of authPriv(3), with authentication protocol
SHA-1 and privacy protocol DES. The authentication text password is “myauthkey”, the
privacy text password is “myprivkey”, and the user is associated with ReadWriteGroup3.
Configuring SNMPv3 Users via SNMP
To configure SNMPv3 users, the EMS must use the standard snmpUsmMIB and the
snmpVacmMIB.
➢ To add a read-only, noAuthNoPriv SNMPv3 user, v3user:
1. Clone the row with the same security level. After the clone step, the status of the row will
be notReady(3).
2. Activate the row. That is, set the row status to active(1).
3. Add a row to the vacmSecurityToGroupTable for SecurityName v3user, GroupName
ReadGroup1 and SecurityModel usm(3).
A row with the same security level (noAuthNoPriv) must already exist in the
usmUserTable. (see the usmUserTable for details).
➢ To delete the read-only, noAuthNoPriv SNMPv3 user, v3user:
1. If v3user is associated with a trap destination, follow the procedure for associating a
different user to that trap destination. (See below.)
2. Delete the vacmSecurityToGroupTable row for SecurityName v3user, GroupName
ReadGroup1 and SecurityModel usm.
3. Delete the row in the usmUserTable for v3user.
➢ To add a read-write, authPriv SNMPv3 user, v3admin1:
1. Clone the row with the same security level.
2. Change the authentication key and privacy key.
3. Activate the row. That is, set the row status to active(1).
4. Add a row to the vacmSecurityToGroupTable for SecurityName v3admin1, GroupName
ReadWriteGroup3 and SecurityModel usm(3).
A row with the same security level (authPriv) must already exist in the usmUserTable
(see the usmUserTable for details).
➢ To delete the read-write, authPriv SNMPv3 user, v3admin1:
1. If v3admin1 is associated with a trap destination, follow the procedure for associating a
different user to that trap destination. (See below.)
