Configuring IP load sharing

• tacacs (port 65)
NOTE
The application names are the names for these applications that the Brocade device recognizes,
and might not match the names for these applications on some third-party devices. The numbers
listed in parentheses are the UDP port numbers for the applications. The numbers come from RFC
1340.
NOTE
As shown above, forwarding support for BootP or DHCP is enabled by default. If you are configuring
the Brocade device to forward BootP or DHCP requests, refer to
“Configuring BootP or DHCP
forwarding parameters” on page 820.
You can enable forwarding for other applications by specifying the application port number.
You also can disable forwarding for an application.
NOTE
If you disable forwarding for a UDP application, forwarding of client requests received as broadcasts
to helper addresses is disabled. Disabling forwarding of an application does not disable other
support for the application. For example, if you disable forwarding of Telnet requests to helper
addresses, other Telnet support on the Brocade device is not also disabled.
Enabling forwarding for a UDP application
If you want the Brocade device to forward client requests for UDP applications that the Brocade
device does not forward by default, you can enable forwarding support for the port. To enable
forwarding support for a UDP application, use either of the following methods. You also can disable
forwarding for an application using these methods.
NOTE
You also must configure a helper address on the interface that is connected to the clients for the
application. The Brocade device cannot forward the requests unless you configure the helper
address. Refer to
“Configuring an IP helper address” on page 821.
To enable the forwarding of specific UDP application broadcasts, enter the following command.
Brocade(config)# ip forward-protocol udp bootpc
Syntax: [no] ip forward-protocol udp udp-port-name | udp-port-num
The udp-port-name parameter can have one of the following values. For reference, the
corresponding port numbers from RFC 1340 are shown in parentheses. If you specify an
application name, enter the name only, not the parentheses or the port number shown here:
• bootpc (port 68)
• bootps (port 67)
• discard (port 9)
• dns (port 53)
• echo (port 7)
• mobile-ip (port 434)
• netbios-dgm (port 138)
