Field
Enables (default) or disables the UPC function.
Select the check box to enable UPC. The circuit tags or drops cells
as they come into the port that do not conform to the configured
traffic descriptors.
Clear the check box to disable UPC. The circuit allows all traffic,
including non-conforming traffic, into the port. As a result, when
you disable UPC, QoS is no longer guaranteed for circuits in the
network due to the potential for increasing the CLR because of
port congestion. For this reason, Lucent recommends that you
enable the UPC function on all circuits.
For information about UPC traffic parameters, see
"Configuring ATM Traffic Descriptors."
To use the UPC function for individual circuits, verify that the
UPC function is enabled for both logical port endpoints on which
you will define the circuit. Enabling UPC at the circuit level has no
effect if you did not enable UPC at the logical port level. UPC is
enabled by default (without the ABR option) for both logical ports
and circuits.
Note: If both endpoints are configured as ATM CE endpoints, the
UPC Function field is not available.
Select the check box to enable Bulk Statistics. This allows you to
configure statistics collection from a circuit using the NavisXtend
Statistics Server.
Clear the check box (default) to disable Bulk Statistics.
Note: If you enable Bulk Statistics at the circuit level, the change
does not take effect unless you first enable Bulk Statistics at the
Switch, Card, and LPort levels.
For information about using the feature, see the NavisXtend
Statistics Server User's Guide.
