Configuring the QoS mappings
These commands configure the mappings displayed 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 command above are shown below
in bold type.
Syntax: [no] qos-tos map dscp-priority <dscp-value> [
The <dscp-value> [<dscp-value> ...] parameter specifies the DSCP value ranges you are
remapping.
You can specify up to eight DSCP values in the same command, to map to the same forwarding
priority. For example
TurboIron(config)#qos-tos map dscp-priority 1 2 3 4 5 6 7 8 to 6.
In releases prior to these, you can specify up to seven DSCP values in the same command.
The <priority> parameter specifies the internal forwarding priority.
Changing the internal forwarding priority –> hardware
forwarding queue mappings
To reassign an internal forwarding priority to a different hardware forwarding queue, enter
commands such as the following at the global CONFIG level of the CLI.
TurboIron(config)#qos tagged-priority 2 qosp0
Syntax: [no] qos tagged-priority <num>
The <num> parameter can be from 0 – 7 and specifies the internal forwarding priority.
The
priority. The default queue names are as follows:
•
qosp7
•
qosp6
•
qosp5
•
qosp4
