3 Interactions based on 802.1p or DSCP/TOS
Step 1. Define the queue, that will be used for packets without any preconfigured rules. Queue 0
has the lowest priority.
ma4000(config)# qos default 0 slot 0
Step 2. Specify the traffic prioritization method using the qos type command. Pass the
prioritization type as a parameter (see Table 15):
ma4000(config)# qos type 1 slot 0
Step 3. Use the qos map command to specify rules of 802.1p and DSCP/TOS translation into the
queue number. Pass the field type and priority list as parameters:
ma4000(config)# qos map 1 0-4,15,63 to 6
ma4000(config)# do show qos
Priority assignment by NONE packet field, all priorities are equal
Default priority queue is 0
DSCP/TOS queues:
0:
1:
2:
3:
4:
5:
6: 0-4,15,63
802.1p queues:
0:
1:
2:
3:
4:
5:
6:
Step 4. Apply the configuration using the commit command:
ma4000(config)# do commit
