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.
