SNMP version 3 traps
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 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.
Restricting SNMP Access to an IPv6 node
You can restrict SNMP access so that the device (including Brocade Network Advisor) can only be
accessed by the IPv6 host address that you specify. To do so, enter a command such as the
following.
TurboIron(config)#snmp-client ipv6 2001:DB8:89::23
Syntax: snmp-client ipv6 <ipv6-address>
The <ipv6-address> must be in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
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.
TurboIron(config)#snmp-server host ipv6 2001:DB8:89::13
Syntax: snmp-server host ipv6 <ipv6-address>
