SNMP Security 377
can view only that portion of the MIB. These views allow access to all MIB
objects according to the existing product access restrictions.
Login usernames are the users’ security names in this model.
The system checks the access rights for all requests against those
applicable to the user's configured access level, that is, the access group.
Two groups are supported:
■
Admin group — View available to Admin group (the highest level)
when connected by authenticated means
■
Monitor group — View available to all other groups, or available when
unauthenticated access is used
By default, you are a member of the Admin group and you set the access
rights of each user (click Network Management > SNMP Settings) .
IF objects are read-only due to context only, the system might return the
existing SMIv1 error code
no-such-name instead of the enhanced
read-only error status on an attempt to set them.
Traps, Notifications,
and Informs
In addition to receiving requests and sending responses to management
applications (managers), agents also can send unsolicited messages to
managers when they detect some significant event. An unsolicited
message is called a
trap (SNMPv1) or a notification (SNMPv2 and
SNMPv3). The NBX SNMP agent supports both traps and notifications in
all three versions of SNMP.
An inform (confirmed notification) is a trap that the agent sends with a
request to the manager to acknowledge the receipt of the trap.
the NBX NetSet utility, where the manager IP address can be configured,
enables you to configure the target entries.
Ton configure the manager IP address:
1 Login to the NBX NetSet utility using the administrator login ID and
password.
2 Click Network Management > SNMP Settings
3 Click the SNMP Managers tab.
4 Click Add or the name of an existing manager.
