This object defines the default ingress Class of Service
of this profile.
If a port has an active policy and the policy's
etsysPolicyProfilePriorityStatus is set to enabled(1), the
etsysPolicyProfilePriority will be applied to all packets
arriving on the port that do not match any of the policy
classification rules.
Note that dot1dPortDefaultUserPriority will still exist
from a management view but will NEVER be applied to traffic
arriving on a port that has an active policy and enabled
etsysPolicyProfilePriority defined, since policy is applied
to traffic arriving on the port prior to the assignment of
a priority using dot1dPortDefaultUserPriority.
The behavior of an enabled etsysPolicyProfilePriority on
any associated port SHALL be identical to the behavior of
the dot1dPortDefaultUserPriority upon that port.
