Basic system parameter configuration
2
When you add a trap receiver, the software automatically encrypts the community string you
associate with the receiver when the string is displayed by the CLI. If you want the software to show
the community string in the clear, you must explicitly specify this when you add a trap receiver. In
either case, the software does not encrypt the string in the SNMP traps sent to the receiver.
To specify the host to which the device sends all SNMP traps, use one of the following methods.
To add a trap receiver and encrypt the display of the community string, enter commands such as
the following.
To specify an SNMP trap receiver and change the UDP port that will be used to receive traps, enter
a command such as the following.
Brocade(config)# snmp-server host 2.2.2.2 0 mypublic port 200
Brocade(config)# write memory
Syntax: snmp-server host <ip-addr> [0 | 1] <string> [port <value>]
The <ip-addr> parameter specifies the IP address of the trap receiver.
The 0 | 1 parameter specifies whether you want the software to encrypt the string (1) or show the
string in the clear (0). The default is 0.
The <string> parameter specifies an SNMP community string configured on the Brocade device.
The string can be a read-only string or a read-write string. The string is not used to authenticate
access to the trap host but is instead a useful method for filtering traps on the host. For example,
if you configure each of your Brocade devices that use the trap host to send a different community
string, you can easily distinguish among the traps from different Brocade devices based on the
community strings.
The command in the example above adds trap receiver 2.2.2.2 and configures the software to
encrypt display of the community string. When you save the new community string to the
startup-config file (using the write memory command), the software adds the following command
to the file.
snmp-server host 2.2.2.2 1 <encrypted-string>
To add a trap receiver and configure the software to encrypt display of the community string in the
CLI , enter commands such as the following.
Brocade(config)# snmp-server host 2.2.2.2 0 FastIron-12
Brocade(config)# write memory
The port <value> parameter allows you to specify which UDP port will be us ed by the trap rece iver.
This parameter allows you to configure several trap receivers in a system. With this parameter, a
network management application can coexist in the same system. Brocade devices can be
configured to send copies of traps to more than one network management application.
Specifying a single trap source
You can specify a single trap source to ensure that all SNMP traps sent by the Layer 3 switch use
the same source IP address. For configuration details, refer to the Brocade ICX 6650 Switch Layer
3 Routing Configuration Guide.
