1. A method, comprising:
identifying, by a network device, a triggering event associated with a logical port, wherein the logical port is associated with a first subscriber group (SGRP) that is associated with a user plane subscriber access device; and
assigning, by the network device, based at least in part on the triggering event, a logical port administrative state to the logical port,
wherein the logical port administrative state is associated with at least one of:
the logical port being moved from the first SGRP to a second SGRP,
a deletion of the logical port due to a cold boot associated with the user plane subscriber access device being in progress,
the user plane subscriber access device entering a quiescent state, and
wherein a packet associated with the logical port is selectively dropped based at least in part on a priority of the packet,
the logical port being enabled, wherein a state associated with the first SGRP is an active state, and wherein an operational state associated with the logical port is an up state, or
the logical port being enabled, wherein a state associated with the first SGRP is a backup state, and wherein an operational state associated with the logical port is a down state.
