6. Configure QoS mapping
Global Mode
mls qos map (cos-dscp <dscp1...dscp8> |
dscp-cos <dscp-list> to <cos> | dscp-mutation
<dscp-mutation-name> <in-dscp> to
<out-dscp> |ip-prec-dscp <dscp1...dscp8> |
policed-dscp (normal-burst | max-burst)
<dscp-li st> to <mark-down-dscp>)
no mls qos map (cos-dscp | dscp-cos |
dscp-mutation
ip-prec-dscp | policed-dscp (normal-burst |
max-burst))
7. Apply QoS to queue of egress port
Interface Mode
queue-bandwidth <queue-id>
<min_kbits_per_se cond>
<max_kbits_per_se cond>
no queue-bandwidth <queue-id>
17.3 QoS Example
Example 1:
Enable QoS function, change the queue out weight of port ethernet 1/1 to 1:1:2:2:4:4:8: 8, and set the port in
trust QoS mode without changing DSCP value, and set the default QoS value of the port to 5.
The configuration steps are listed below:
XGS 3-42000R#config
XGS 3-42000R(config)#mls qos
XGS 3-42000R(config)#interface ethernet 1/1
XGS 3-42000R(config-If-Ethernet1/1)#wrr-queue bandwidth 1: 1:2:2:4:4:8:8
XGS 3-42000R(config-If-Ethernet1/1)#mls qos trust cos pass-through-dscp
XGS 3-42000R(config-If-Ethernet1/1)#mls qos cos 5
