udp-port-list: The broadcast packet destination UDP port number to forward. If not specified,
packets for the default services are forwarded to the helper address. Valid range, 0-65535.
Default
Format ip helper-address <ip-address>
{<1-65535>|dhcp|domain|isakmp|mobile-ip|nameserver|
netbios-dgm|netbios-ns|ntp|pim-auto-rip|rip|tacacs|tftp|time}
Mode
no ip helper-address (Global Config)
Use this command to remove the IP address from the previously configured list. The no
command without an <ip-address> argument removes the entire list of helper addresses
on that interface.
Format no ip helper-address {<ip-address>}
{<1-65535>|dhcp|domain|isakmp|mobile-ip|nameserver|
netbios-dgm|netbios-ns|ntp|pim-auto-rip|rip|tacacs|tftp|time}
Mode
ip helper enable
Use this command to enable relay of UDP packets. This command can be used to
temporarily disable IP helper without deleting all IP helper addresses. This command
replaces the bootpdhcprelay enable command, but affects not only relay of DHCP
packets, but also relay of any other protocols for which an IP helper address has been
configured.

Format ip helper enable
Mode
no ip helper enable
