Configuring the QoS mappings
15
PowerConnect(config)#qos-tos map dscp-priority 40 to 7
PowerConnect(config)#qos-tos map dscp-priority 48 to 3
PowerConnect(config)#qos-tos map dscp-priority 56 to 6
PowerConnect(config)#ip rebind-ACL all
The first command in the above example maps priority 1 to DSCP values 0, 2, 3, and 4.
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> [<dscp-value> ...] to <priority>
The <dscp-value> [<dscp-value> ...] parameter specifies the DSCP value ranges you are
remapping.
PowerConnect B-Series TI24X devices, you can specify up to eight DSCP values in the same
command, to map to the same forwarding priority. For example
PowerConnect(config)#qos-tos map dscp-priority 1 2 3 4 5 6 7 8 to 6.
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.
PowerConnect(config)#qos tagged-priority 2 qosp0
Syntax: [no] qos tagged-priority <num> <queue>
The <num> parameter can be from 0 – 7 and specifies the internal forwarding priority.
The <queue> parameter specifies the hardware forwarding queue to which you are reassigning the
priority. The default queue names are as follows:
• qosp7
