C613-50631-01 Rev A Command Reference for IE340 Series 3076
AlliedWare Plus™ Operating System - Version 5.5.3-0.x
DYNAMIC HOST CONFIGURATION PROTOCOL (DHCP) COMMANDS
OPTION
option
Overview This command adds a user-defined option to the DHCP address pool you are
configuring. For the hex, integer, and flag option types, if the option already
exists, the new option overwrites the existing option’s value. Options with an ip
type can hold a list of IP addresses or masks (i.e. entries that have the A.B.C.D
address format), so if the option already exists in the pool, then the new IP address
is added to the list of existing IP addresses.
Options with the same number as one of the pre-defined options override the
standard option definition. The pre-defined options use the option numbers 1, 3,
6, 15, and 51.
The no variant of this command removes the specified user-defined option from
the DHCP pool, or all user-defined options from the DHCP pool.
