Release Information Statement introduced in Junos OS Release 10.0.
Support at the [edit ... dhcpv6 ...] hierarchy levels introduced in Junos OS Release 10.4.
Statement introduced in Junos OS Release 12.1 for EX Series switches.
support-option-pd-exclude statement introduced in Junos OS Release 17.3 for the MX
Series.
Description Enable dynamic reconfiguration triggered by the DHCP local server of all DHCP clients
or only the DHCP clients serviced by the specified group of interfaces. A group
configuration takes precedence over a DHCP local server configuration. The strict
