| Description | Indicates the operational source of QoS provisioning policy
for this interface.
When the value of the object qosPrOperPolicySource is
local(2), the QoS provisioning policy for this interface is
taken from device's local configuration. If
qosPrOperPolicySource is configured to cops(3), the current
operational source of QoS provisioning policy will depend on
the configuration of qosPrIfAdminPolicySource object.
Here is the logic.
IF qosPrOperPolicySource == local(2)
THEN qosPrIfOperPolicySource is local(2)
ELSE
IF qosPrOperPolicySource == cops(3)
THEN
IF qosPrIfAdminPolicySource == cops(3)
THEN qosPrIfOperPolicySource is cops(3)
ELSE qosPrIfOperPolicySource is local(2)
ELSE
qosPrIfOperPolicySource is none(1)
END
END
For example, if qosPrOperPolicySource shows local(2), although
the qosPrIfAdminPolicySource is configured cops(3), the QoS
provisioning policy running on this interface is from local
device configuration. It means this object will be local(2).
Note that when qosPrIfAdminPolicySource transitions to
cops(3) if qosPrOperPolicySource is cops(3),
qosPrIfOperPolicySource will normally also transition to
cops(3). In this situation, it is possible that
qosPrIfOperPolicySource's transition will not occur immediately
because the system is initializing the COPS function at the
system boot up time, but rather after a small time lag to
complete certain operations before going 'cops'. |
