The value of tmnxSLAProfEgrSchedulerType specifies the type of
scheduling for queued traffic.
If set to 'portScheduler (1)' the subscriber host queues will be
parented to the port scheduler.
If set to 'vportScheduler (2)' the subscriber host queues will be
parented to a virtual port, which will be derived by performing
a lookup with the subscriber host's intermediate destination id
and organization string in the
TIMETRA-PORT-MIB::tPortEgrVPortHostMatchTable.
