User Settings fields (Sheet 1 of 2)

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.

messages and alarm messages.

New SNMPv3 users are not granted any priviledges 
initially.
