Viewing and configuring IEEE 802.1p bits and QoS levels

You can view and configure the mapping between the IEEE 802.1p bits and QoS levels. For bridged, tagged traffic, the switch determines the QoS level based on the IEEE 802.1p bits and the mapping of those bits to QoS levels via the Ingress TagToQos mapping table.


Note Note: Nortel Networks recommends not changing the default values. If you change the values, make sure that the values are consistent on all other Passport switches and other devices in your network. Inconsistent mapping of table values can result in unpredictable service levels.

To view and configure IEE 802.1p bit and QoS level mapping:


From the Device Manager menu bar, choose QOS > QOS>
Ingress TagToQos.


The QOS dialog box opens with the Ingress TagToQos tab displayed.

The table below describes the Ingress TagToQos tab fields.


Field Description
Row
Represents eight egress QoS levels.
InIeee8021P
Value of the IEEE802.1 p bit of the incoming packet.
QosLevel
Equivalent QoS level (0 to 7).
