Displaying Qos Configuration Information; Mappings - Dell PowerConnect B-RX Configuration Manual

The <priority> parameter specifies the internal forwarding priority.
Changing the CoS –> internal forwarding priority

mappings

This mapping is used when the trust level is set to CoS. In addition to determining the
internal-forwarding priority of a packet, the value also determines the outbound 802.1p value if
CoS marking is enabled. To change the
CoS –> internal forwarding priority mappings for all the CoS ranges, enter commands such as the
following at the global CONFIG level of the CLI.
BigIron RX(config)# qos-tos map cos-priority 7 4 3 6 5 2 1 0
These commands configure the mappings displayed in the CoS to forwarding priority portion of the
QoS information display. To read this part of the display, select the first part of the CoS value from
the d1 column and select the second part of the CoS value from the d2 row. For example, to read
the CoS to forwarding priority mapping for CoS value 24, select 2 from the d1 column and select 4
from the d2 row. The mappings that are changed by the command above are shown below in bold
type.

Syntax: [no] qos-tos map cos-priority <prio0> <prio1><prio2><prio3><prio4><prio5><prio6>
The <prio0> through <prio7> parameters specify the COS values you are mapping the eight
internal priorities to. You must enter CoS values for all eight internal priorities, in order from priority
0 – 7.
