SNMP version 3 traps
6
To configure an SNMP user group, first configure SNMPv3 views using the snmp-server view
command. Refer to “SNMP v3 configuration examples” on page 176. Then enter a command such
as the following.
Brocade(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.
Defining the UDP port for SNMP v3 traps
The SNMP host command enhancements allow configuration of notifications in SMIv2 format, with
or without encryption, in addition to the previously supported SMIv1 trap format.
You can define a port that receives the SNMP v3 traps by entering a command such as the
following.
Brocade(config)#snmp-server host 192.168.4.11 version v3 auth security-name port
4/1
Syntax: [no] snmp-server host ip-addr | ipv6-addr version [ v1 | v2c community-string | v3 auth |
noauth | priv security-name] [port trap-UDP-port-number]
The ip-addr parameter specifies the IP address of the host that will receive the trap.
For version, indicate one of the following
For SNMP version 1, enter v1 and the name of the community string (community-string). This
string is encrypted within the system.
