◆ Egress packets are placed into the hardware queues according to the
mapping defined by this command.
◆ The default internal PHB to output queue mapping is shown below.
◆ The specified mapping applies to all interfaces.

ARAMETERS
These parameters are displayed:
◆
PHB – Per-hop behavior, or the priority used for this router hop.
(Range: 0-7, where 7 is the highest priority)
◆
Queue – Output queue buffer. (Range: 0-3, where 3 is the highest CoS
priority queue)

To map internal PHB to hardware queues:
1.
Click Traffic, Priority, PHB to Queue.
2.
Select Add from the Action list.
3.
Set the queue mode.
4.
Map an internal PHB to a hardware queue. Depending on how an
ingress packet is processed internally based on its CoS value, and the
assigned output queue, the mapping done on this page can effectively
determine the service priority for different traffic classes.
5.
Click Apply.
