User Settings fields (Sheet 1 of 2)

Field Description

Index Specifies a unique integer in the range 1 to 1023 to identify

this SNMPv3 User on the Nortel SNAS 4050 cluster.

This field cannot be changed after an SNMPv3 user is

added.

Name Specifies a name for the USM user. The name must be

unique in the cluster.

Security Level Specifies the degree of SNMP USM security. Valid options

are:

• none — SNMP access is granted without

authentication.

• auth — the 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 — the 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).

Permission Specifies the USM user’s privileges. Valid options are:

• get — USM user is authorized to perform SNMP get

requests (read access to the MIB).

• set — USM user is authorized to perform SNMP set

requests (write access to the MIB). Write access

automatically implies read access as well.

• trap — USM user is authorized to receive trap event

messages and alarm messages.

New SNMPv3 users are not granted any priviledges

initially.

Authentication Password Specifies the password for USM user authentication. The

password is required if the security level is set to auth or

priv. The password must be at least eight characters long.

Privacy Password Specifies the USM user’s individual encryption key. The

password is required if the security level is set to priv. The

password must be at least eight characters long.
