forwarding 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.

The <num> variable can be from 0 through 7 and specifies the VLAN priority.

priority. The default queue names are as follows:
• qosp7
• qosp6

• qosp4
• qosp3
• qosp2
• qosp1
• qosp0
