undo udp-helper port { port-number | dns | netbios-ds | netbios-ns | tacacs | tftp | time } Default No UDP port number is specified for UDP helper. Views System view Predefined user roles network-admin Parameters port-number: Specifies a UDP port number in the range of 1 to 65535 (except 67 and 68). dns: Specifies the UDP port 53 used by DNS packets. netbios-ds: Specifies the UDP port 138 used by NetBIOS datagram distribution service packets. netbios-ns: Specifies the UDP port 137 used by NetBIOS name service packets. tacacs: Specifies the UDP port 49 used by TACACS packets. tftp: Specifies the UDP port 69 used by TFTP packets. time: Specifies the UDP port 37 used by time protocol packets. Usage guidelines To specify a UDP port, you can specify the port number or the corresponding protocol keyword. For example, udp-helper port 53 and udp-helper port dns specify the same UDP port. UDP helper will process UDP broadcast packets destined for the specified UDP port and forward them to the destination server. You can specify a maximum of 256 UDP ports on a device. Examples # Enable UDP helper to forward broadcast packets with UDP destination port 100. system-view [Sysname] udp-helper port 100 udp-helper server Use udp-helper server to specify a destination server for UDP helper. Use undo udp-helper server to remove a destination server for UDP helper. Syntax udp-helper server ip-address undo udp-helper server [ ip-address ] Default No destination server is specified.
