You can exclude portions of the MIB within an inclusion scope. For example, if you want to exclude the
snAgentSys objects, which begin with 1.3.6.1.4.1.1991.1.1.2 object identifier from the admin view,
enter a second command such as the following.

device(config)#snmp-server view admin 1.3.6.1.4.1.1991.1.1.2 excluded

NOTE
Note that the exclusion is within the scope of the inclusion.

To delete a view, use the no parameter before the command.

SNMP version 3 traps

Brocade devices support SNMP notifications in SMIv2 format. This allows notifications to be encrypted
and sent to the target hosts in a secure manner.

Defining an SNMP group and specifying which view is notified of traps

The SNMP group command allows configuration of a viewname for notification purpose, similar to the
read and write view. The default viewname is "all", which allows access to the entire MIB.

To configure an SNMP user group, first configure SNMPv3 views using the snmp-server view
command. Refer to

SNMP v3 configuration examples

on page 151. Then enter a command such as

the following.

device(config)#snmp-server group admin v3 auth read all write all

notify all

Syntax: [no] snmp-server group groupname v1 | v2 | v3 auth | noauth | priv [ access standard-
ACL-id
] [ read viewstring | write viewstring | notify viewstring ]

The group groupname parameter defines the name of the SNMP group to be created.

The v1 , v2 , or v3 parameter indicates which version of SNMP to use. In most cases, you will use v3,
since groups are automatically created in SNMP versions 1 and 2 from community strings.

The auth | noauth parameter determines whether or not authentication will be required to access the
supported views. If auth is selected, then only authenticated packets are allowed to access the view
specified for the user group. Selecting noauth means that no authentication is required to access the
specified view. Selecting priv means that an authentication password will be required from the users.

The access standard-ACL-id parameter is optional. It allows incoming SNMP packets to be filtered
based on the standard ACL attached to the group.

The read viewstring | write viewstring parameter is optional. It indicates that users who belong to this
group have either read or write access to the MIB.

The notify view allows administrators to restrict the scope of varbind objects that will be part of the
notification. All of the varbinds need to be in the included view for the notification to be created.

The viewstring variable is the name of the view to which the SNMP group members have access. If no
view is specified, then the group has no access to the MIB.
