SNMP version 3 traps
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.
Backward compatibility with SMIv1 trap format
The Brocade device will continue to support creation of traps in SMIv1 format, as before. To allow
the device to send notifications in SMIv2 format, configure the device as described above. The
default mode is still the original SMIv1 format.
Specifying an IPv6 host as an SNMP trap receiver
You can specify an IPv6 host as a trap receiver to ensure that all SNMP traps sent by the device will
go to the same SNMP trap receiver or set of receivers, typically one or more host devices on the
network. To do so, enter a command such as the following.
Brocade(config)#snmp-server host ipv6 2001:efff:89::13
Syntax: snmp-server host ipv6 <ipv6-address>
The <ipv6-address> must be in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
