SNMP version 3 traps

6

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.

NOTE

If the configured version is v2c, then the notification is sent out in SMIv2 format, using the community string, but in cleartext mode. To send the SMIv2 notification in SNMPv3 packet format, configure v3 with auth or privacy parameters, or both, by specifying a security name. The actual authorization and privacy values are obtained from the security name.

For SNMP version 2c, enter v2 and the name of the community string. This string is encrypted within the system.

For SNMP version 3, enter one of the following depending on the authorization required for the host:

v3 auth <security-name>: Allow only authenticated packets.

v3 no auth <security-name>: Allow all packets.

v3 priv <security-name>: A password is required

For port <trap-UDP-port-number>, specify the UDP port number on the host that will receive the trap.

Trap MIB changes

To support the SNMP V3 trap feature, the Brocade Enterprise Trap MIB was rewritten in SMIv2 format, as follows:

The MIB name was changed from FOUNDRY-SN-TRAP-MIB to FOUNDRY-SN-NOTIFICATION-MIB

Individual notifications were changed to NOTIFICATION-TYPE instead of TRAP-TYPE.

As per the SMIv2 format, each notification has an OID associated with it. The root node of the notification is snTraps (OID enterprise.foundry.0). For example, OID for snTrapRunningConfigChanged is {snTraps.73}. Earlier, each trap had a trap ID associated with it, as per the SMIv1 format.
