ProSafe 7200 Managed Switches CLI Manual, Software Version 8.0.3 ip helper-address Use this command to add a unicast helper address to the list of helper addresses on an interface. This is the address of a DHCP server. This command can be applied multiple times on the routing interface to form the helper addresses list until the list reaches the maximum supported helper addresses. Format Mode ip helper-address {|dhcp|domain|isakmp|mobile-ip|nameserver| netbios-dgm|netbios-ns|ntp|pim-auto-rip|rip|tacacs|tftp|time} Interface Config no ip helper-address Use this command to remove the IP address from the previously configured list. The no command without an argument removes the entire list of helper addresses on that interface. Format Mode no ip helper-address {} {|dhcp|domain|isakmp|mobile-ip|nameserver| netbios-dgm|netbios-ns|ntp|pim-auto-rip|rip|tacacs|tftp|time} Interface Config ip helper-address discard Use this command to drop matching packets. Format Mode ip helper-address discard {|dhcp|domain|isakmp|mobile-ip|nameserver| netbios-dgm|netbios-ns|ntp|pim-auto-rip|rip|tacacs|tftp|time} Interface Config no ip helper-address discard Use this command to permit the matching packets.
