NOTE
The application names are the names for these applications that the Virtual ADX 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
As shown above, forwarding support for BootP/DHCP is enabled by default. If you are configuring the
Virtual ADX to forward BootP/DHCP requests, refer to
“Configuring BootP/DHCP forwarding
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 Virtual ADX is not also disabled.
Enabling forwarding for a UDP application
If you want the Virtual ADX to forward client requests for UDP applications that the Virtual ADX 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 Virtual ADX cannot forward the requests unless you configure the helper address.
Refer to
“Configuring an IP helper address”
To enable the forwarding of SNMP trap broadcasts, enter the following command.
Virtual ADX(config)# ip forward-protocol udp
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)
•
dnsix (port 90)
•
echo (port 7)
•
mobile-ip (port 434)
•
netbios-dgm (port 138)
