Configuring IP parameters – Layer 3 Switches
NOTE
The application names are the names for these applications that the Layer 3 Switch software
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
Forwarding support for BootP/DHCP is enabled by default. If you are configuring the Layer 3 Switch
to forward BootP/DHCP requests, refer to
“Configuring BootP/DHCP relay parameters” on page 483.
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 Layer 3 Switch is not also disabled.
Enabling forwarding for a UDP application
If you want the Layer 3 Switch to forward client requests for UDP applications that the Layer 3
Switch does not forward by default, you can enable forwarding support for the port. To enable
forwarding support for a UDP application, use the following method. You also can disable
forwarding for an application using this method.
To enable the forwarding of SNMP trap broadcasts, enter the following command.
TurboIron(config)#ip forward-protocol udp snmp-trap
Syntax: [no] ip forward-protocol udp |
The 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)
• dnsix (port 90)
• echo (port 7)
• mobile-ip (port 434)
• netbios-dgm (port 138)
• netbios-ns (port 137)
• ntp (port 123)
• tacacs (port 65)
• talk (port 517)
• time (port 37)
