This section describes commands used to configure Layer 3 and 4 traffic
priority mapping on the switch.

This command maps CoS/CFI values in incoming packets to per-hop
behavior and drop precedence values for priority processing. Use the
no
form to restore the default settings.

- Per-hop behavior, or the priority used for this router hop.
(Range: 0-7)
drop-precedence
- Drop precedence used for Random Early
Detection in controlling traffic congestion. (Range: 0 - Green,
3 - Yellow, 1 - Red)
cos
- CoS value in ingress packets. (Range: 0-7)

Maps CoS/CFI values in incoming packets to per-hop
behavior and drop precedence values for internal
priority processing
IC
Maps DSCP values in incoming packets to per-hop
behavior and drop precedence values for internal
priority processing
IC
Maps internal per-hop behavior values to hardware
queues
IC
Sets QoS mapping to DSCP or CoS
IC
Shows ingress DSCP to internal DSCP map
PE
Shows internal per-hop behavior to hardware queue
map
PE
Shows ingress CoS to internal DSCP map
PE
Shows the QoS mapping mode
PE
* The default settings used for mapping priority values to internal DSCP values and back to
the hardware queues are designed to optimize priority services for the majority of network
applications. It should not be necessary to modify any of the default settings unless a
queuing problem occurs with a particular application.
