16.2.2.13 mls qos dscp-mutation
Command: mls qos dscp-mutation <dscp-mutation-name>
no mls qos dscp-mutation <dscp-mutation-name>
Function: Applies DSCP mutation mapping to the port; the “no mls qos dscp-mutation
<dscp-mutation-name>” command restores the DSCP mutation mapping default.
Parameters: <dscp-mutation-name> is the DSCP mutation mapping name.
Default: There is no policy by default.
Command mode: Interface Mode
Usage Guide: For configuration of DSCP mutation mapping on the port to take effect, the trust
status of that port must be “trust DSCP”. Applying DSCP mutation mapping allows
DSCP values specified directly to be converted into new DSCP values without class
and policy process. DSCP mutation mapping is effective to the local port only. “trust
DSCP” refers to the DSCP value before DSCP mutation in this case.
Example: Configuring Ethernet port 1/1 to trust DSCP, using DSCP mutation mapping of mu1.
Switch(Config)#interface ethernet 1/1
Switch(Config-Ethernet1/1)#mls qos trust dscp pass-through cos
Switch(Config-Ethernet1/1)#mls qos dscp-mutation mu1
16.2.2.14 wrr-queue bandwidth
Command: wrr-queue bandwidth
weight8>
no wrr-queue bandwidth
Function: Sets the WRR weight for specified egress queue; the “no wrr-queue bandwidth”
command restores the default setting.
Parameters: are WRR
weights, ranging from 0 to 15.
Default: The default values of weight1 to weight8 are 1 through 8. .
Command mode: Interface Mode
Usage Guide: The absolute value of WRR is meaningless. WRR allocates bandwidth by using eight
weight values. If a weight is 0, then the queue has the highest priority; when the
weights of multiple queues are set to 0, then the queue of higher order has the higher
priority.
Example: Setting the bandwidth weight proportion of the eight queue out to be 1:1:2:2:4:4:8:8.
Switch(Config-Ethernet1/1)#wrr-queue bandwidth 1 1 2 2 4 4 8 8
16.2.2.15 priority-queue out
Command: priority-queue out
no priority-queue out
