Nortel Secure Network Access Switch 4050 User Guide
Configuring SNMPv3 users using the CLI
The Nortel SNAS 4050 manages SNMPv3 users based on the User-based Security
Model (USM) for SNMP version 3. For more information about USM, see
RFC2274.
To manage SNMPv3 users in the Nortel SNAS 4050 configuration, use the
following command:
/cfg/sys/adm/snmp/users < user ID >
where user ID is an integer in the range 1 to 1023 that uniquely identifies the
SNMPv3 user in the Nortel SNAS 4050 cluster.
When you first create the user, you must enter the user ID. After you have created
the user, you can use either the ID or the name to access the user for configuration.
When you first create the user, you are prompted to enter the following
parameters:
• user name — a string that uniquely identifies the USM user in the Nortel
SNAS 4050 cluster. The maximum length of the string is 255 characters.
After you have defined a name for the user, you can use either the user name
or the user ID to access the
SNMP User menu.
• security level — the degree of SNMP USM security. Valid options are:
•
none
— SNMP access is granted without authentication.
•
auth
— SNMP user must provide a verified password before SNMP
access is granted. You are later prompted to specify the required password
(auth password). SNMP information is transmitted in plain text.
•
priv
— SNMP user must provide a verified password before SNMP
access is granted, and all SNMP information is encrypted with the user’s
individual key. You are later prompted to specify the required password
(auth password) and encryption key (priv password).
The default is
priv
.
• permission — the USM user’s privileges. Valid options are:
•
get
— USM user is authorized to perform SNMP get requests (read
access to the MIB).
