Release Information Statement introduced in Junos OS Release 9.3.
Support at the [edit ... dhcpv6] hierarchy levels introduced in Junos OS Release 11.4.
Statement introduced in Junos OS Release 12.1 for EX Series switches.
Support at the [edit ... dual-stack-group dual-stack-group-name] hierarchy level introduced
in Junos OS Release 15.1.
Description Specify the dynamic profile to configure as the primary dynamic profile. The primary
dynamic profile is instantiated when the first subscriber logs in. Subsequent subscribers
are not assigned the primary dynamic profile; instead, they are assigned the dynamic
profile specified for the interface. When the first subscriber logs out, the next subscriber
that logs in is assigned the primary dynamic profile.
Use the statement at the [edit ... dhcpv6] hierarchy levels to configure DHCPv6 support.
EX Series switches do not support DHCPv6.
