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.
device(config)#snmp-server host ipv6 2001:DB8:89::13
Syntax:
snmp-serverhost
ipv6
ipv6-address
The
ipv6-address
must be in hexadecimal format using 16-bit values between colons as documented in
RFC 2373.
SNMP v3 over IPv6
Some FastIron devices support IPv6 for SNMP version 3.
