DHCP client options

When an interface is in DHCP addressing mode, DHCP client options can be configured in the CLI. For example, a vendor class identifier (usually DCHP client option 60) can be specified so that a request can be matched by a specific DHCP offer.

Multiple options can be configured, but any options not recognized by the DHCP server are discarded.

To configure client option 60 - vendor class identifier:
config system interface
    edit port1
        set vdom vdom1
        set mode dhcp
        config client-options
            edit 1
                set code 60
                set type hex
                set value aabbccdd
            next
        end
        set type physical
        set snmp-index 4
    next
end
