This output displays mappings in the DSCP to forwarding priority portion of the QoS information display.
To read this part of the display, select the first part of the DSCP value from the d1 column and select
the second part of the DSCP value from the d2 row. For example, to read the DSCP to forwarding
priority mapping for DSCP value 24, select 2 from the d1 column and select 4 from the d2 row. The
mappings that are changed by the example qos-tos map dscp-priority command are shown in bold
type.
Changing the VLAN priority 802.1p to hardwareforwarding queue
mappings
To map a VLAN priority to a different hardware forwarding queue, enter commands such as the
following at the global CONFIG level of the CLI.
Syntax: [no] qos tagged-priority num queue
The num variable can be from 0 through 7 and specifies the VLAN priority.
The queue variable specifies the hardware forwarding queue to which you are reassigning the priority.
The default queue names are as follows:
• qosp7
• qosp6
• qosp5
• qosp4
• qosp3
• qosp2
• qosp1
• qosp0
Following is an example of using this command.
device(config)#qos tagged-priority 2 qosp0
