Description
Define the traffic class map for a packet on the basis of the CoS code points.
Traffic class map is a user-configurable input priority map that helps prioritize and classify traffic entering a Packet Forwarding Engine during ingress oversubscription. You can define traffic class maps for a packet on the basis of the following CoS code points:
Differentiated Services code point (DSCP) for IP DiffServ
IP precedence bits
MPLS EXP bits
IEEE 802.1 bits
IEEE 802.1ad drop eligible indicator (DEI) bits
You can associate the code point values to one of the following traffic classes:
Real-time
Network control
Best-effort
Options
dscp—DSCP traffic class map.
Applies to both IPv4 and IPv6 traffic.
exp—MPLS EXP traffic class map.
ieee-802.1—IEEE 802.1 traffic class map.
ieee-802.1ad—IEEE 802.1ad traffic class map.
inet-precedence—IPv4 precedence traffic class
map.
traffic-class-map-name—Name
of the input priority map.
traffic-class best-effort—Map code points to
a best-effort traffic class.
traffic-class network-control—Map code points
to a network control traffic class.
traffic-class real-time—Map code points to
a real-time traffic class.
code-points [code-point-alias | code-point-value]—List of code point aliases and bit strings.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
