Modifying Queuing Class Maps For Cos - Cisco Nexus 7000 Series Configuration Manual

Modifying Queuing Class Maps for COS

Note When DSCP is enabled and configured on a queue, and if the port is untrusted, and an ingress port cos is
configured, DSCP is considered for queuing.

Modifying Queuing Class Maps for COS
You can modify the CoS values that are matched by system-defined class maps. See
Type queuing Class Maps, on page 15
The system-defined class maps can be changed only from the default VDC. Changes occur immediately and
are applied to all ports on all VDCs that use the modified class map.
Note When you modify a system-defined class map, the changes occur immediately and might disrupt traffic on
all VDCs that use the modified class map.

Configuring Queuing and Scheduling on M-Series I/O Modules
Purpose
Enters global configuration mode.
Configures the policy map of type queuing, and
then enters policy-map mode for the policy-map
name that you specify. Policy-map names can
contain alphabetic, hyphen, or underscore
characters, are case sensitive, and can be up to
40 characters.
Configures the class map of type queuing, and
then enters policy-map class queuing mode.
Note To configure port CoS, you can use
only an ingress default
system-defined queue type.
Sets the CoS field in all ingress packet to the
value specified. The range is from 0 to 7.
Exits policy-map queue mode, and enters global
configuration mode.
Displays information about all configured
