Cisco Nexus 5500 Series NX-OS User Manual

PurposeCommand or Action
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
The associated class map must be the same type as the
policy map type.
Note
switch(config-pmap-nq)# class
type network-qos class-name
Step 6
Configures a no-drop class. If you do not specify this command,
the default policy is drop.
The operation for the drop policy is a simple tail drop,
where arriving packets will be dropped if the queue
increases to its allocated size.
The pfc-cos-value range is from 0 to 7. This option is
supported only for a ACL-based system class (which
filters traffic using criteria other than cos-based
matches).
Note
The list of CoS values can potentially
include the CoS value that is used for FCoE
traffic in class-fcoe. You must determine if
this is desired behavior for your topology.
Caution
switch(config-pmap-c-nq)#
pause no-drop [pfc-cos
pfc-cos-value]
Step 7
Associates a class map with the policy map, and enters
configuration mode for the specified system class.
The associated class map must be the same type as the
policy map type.
Note
switch(config-pmap-nq)# class
type network-qos class-name
Step 8
Enables the jumbo MTU for the whole switch by setting the
MTU to its maximum size (9216 bytes) in the policy map for
the default system class (class-default).
switch(config-pmap-c-nq)# mtu
9216
Step 9
This example shows how to configure a no-drop policy map.
switch# configure terminal
switch(config)# class-map type network-qos c1
switch(config-cmap-nq)# match qos-group 2
switch(config-cmap-nq)# exit
switch(config)# policy-map type network-qos p1
switch(config-pmap-nq)# class type network-qos c1
switch(config-pmap-c-nq)# pause no-drop
switch(config-pmap-nq)# class type network-qos class-default
switch(config-pmap-c-nq)# mtu 9216
