Chapter 37: Class of Service Commands
Priority Commands (Layer 3 and 4)
– 1129 –
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)

•
Enter a queue identifier, followed by the keyword “from” and then up to
eight internal per-hop behavior values separated by spaces.
•
Egress packets are placed into the hardware queues according to the
mapping defined by this command.
•
The specified mapping applies to all interfaces.

Console(config)#qos map phb-queue 0 from 1 2 3
Console(config)#
qos map trust-mode
This command sets QoS mapping to DSCP or CoS. Use the no form to
restore the default setting.

qos map trust-mode { ip-prec | dscp | cos }
no qos map trust-mode
dscp - Sets the QoS mapping mode to DSCP.
cos - Sets the QoS mapping mode to CoS.

•
If the QoS mapping mode is set to IP Precedence with this command,
and the ingress packet type is IPv4, then priority processing will be
based on the IP Precedence value in the ingress packet.
