queue-0<1-55> is the lowest priority, queue-1 is low priority, queue-2 is high priority

7.2.6
VLAN priority mapping configuration
The ESML6-P3 switch supports the 802.1p-based priority scheduling strategy. 802.1p
priority determines a message priority by the VLAN tag priority in the 802.1Q messages.
When the message enters the switch in the untagged mode, the switch adds them into
VLAN Tag according to port’s 802.1p priority which is regarded as the message priority.
802.1p priority configuration of ports is described in the port configuration.
To configure the 802.1p-based scheduling strategy, the mapping relation is showed in
the table below at the default state:
802.1p priority
Priority queue
6 – 7
Queue 3 (highest priority)
4 – 5
Queue 2 (high priority)
2 – 3
Queue 1 (low priority)
0 – 1
Queue 0 (lowest priority)
VLAN priority mapping configuration:
SWITCH(config)# qos vlan priority <0-7> map queue <0-3>
7.2.7
TOS priority mapping configuration
The default mapping relations are shown in the following table:
IP ToS priority
Priority
6 – 7
Queue 3 (highest priority)
4 – 5
Queue 2 (high priority)
2 – 3
Queue 1 (low priority)
0 – 1
Queue 0 (lowest priority)
TOS priority mapping configuration
