12.2.5.2 ip forward-protocol
Use this command to enable UDP broadcast forwarding and specify which protocols will be
forwarded. This command works in conjunction with the
ip helper-address command to configure
UDP broadcast forwarding. For information on specifying a new destination for UDP broadcasts,
refer to
Section 12.2.5.3 .
ip forward-protocol { udp [ port ]}
Syntax Description
Command Syntax of the “no” Form
The “no” form of this command removes a UDP port or protocol, disabling
forwarding:
no ip forward-protocol { udp [ port ]}
Command Type
Router command.
Command Mode
Global configuration: Matrix>Router(config)#
udp Specifies UDP as the IP forwarding protocol.
port (Optional) Specifies a destination port that controls which
UDP services are forwarded. If not specified, the forwarding
protocols are forwarded on the default ports listed:
•
Trivial File Transfer Protocol (TFTP) (port69)
•
Domain Naming System (port 53)
•
Time service (port 37)
•
NetBIOS Name Server (port 137)
•
NetBIOS Datagram Server (port 138)
•
TACACS service (port 49)
•
EN-116 Name Service (port 42)
NOTE: If a certain service exists inside the node,
and there is no need to forward the request to
remote networks, the “no” form of this command
should be used to disable the forwarding for the
specific port. Such requests will not be
automatically blocked from being forwarded, just
because a service for them exists in the node.
