Table 110: Mapping Internal Per-Hop Behavior To Hardware Queues; Qos Map Phb-Queue - Edge-Core ECS4210-12P Reference Manual

qos map phb-queue

to match the definition of another domain. The mutation map should be
applied at the receiving port (ingress mutation) at the boundary of a QoS
administrative domain.
Example
This example changes the priority for all packets entering port 1 which contain a
DSCP value of 1 to a per-hop behavior of 3 and a drop precedence of 1. Referring to
Table 109, note that the DSCP value for these packets is now set to 25 (3x2
passed on to the egress interface.
Console(config)#interface ethernet 1/5
Console(config-if)#qos map dscp-mutation 3 1 from 1
Console(config-if)#
This command determines the hardware output queues to use based on the
internal per-hop behavior value. Use the no form to restore the default settings.
Syntax
qos map phb-queue queue-id from phb0 ... phb7
no map phb-queue phb0 ... phb7
phb - Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
queue-id - The ID of the priority queue. (Range: 0-7, where 7 is the highest
priority queue)

Egress packets are placed into the hardware queues according to the mapping
defined by this command.
