priority processing. Use the no form to restore the default settings.
Syntax
qos map dscp-queue dscp-queue from dscp0 ... dscp7
no qos map dscp-queue dscp0 ... dscp7
dscp-queue - Per-hop behavior, or the priority used for this router hop.
(Range: 0-7)
dscp - DSCP value in ingress packets. (Range: 0-63)
DEFAULT SETTING
Command Mode
Interface Configuration (Ethernet)
Command Usage
Enter a value for the per-hop behavior, followed by the keyword “from” and
then up to eight DSCP values separated by spaces.
This map is only used when the QoS mapping mode is set to “DSCP by the qos
map trust-mode command, and the ingress packet type is IPv4.
Two QoS domains can have different DSCP definitions, so the DSCP-to-Queue/
map can be used to modify one set of DSCP values to match the definition of
another domain. This map should be applied at the receiving port at the
boundary of a QoS administrative domain.
