DescriptionArgument
NetBIOS Extended User Interface (NetBEUI)netbios
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Creates a named object that represents a class of
traffic. Class-map names can contain alphabetic,
switch(config)# class-map type qos
class-name
Step 2
hyphen, or underscore characters, are case
sensitive, and can be up to 40 characters.
Configures the traffic class by matching packets
based on the specified protocol.
switch(config-cmap-qos)# match protocol
{arp | clns_es | clns_is | dhcp | ldp |
netbios}
Step 3
(Optional)
Removes the match from the traffic class.
switch(config-cmap-qos)# no match
protocol {arp | clns_es | clns_is | dhcp | ldp
| netbios}
Step 4
This example shows how to classify traffic by matching packets based on the protocol field:
switch# configure terminal
switch(config)# class-map type qos class_protocol
switch(config-cmap-qos)# match protocol arp
Use the show class-map command to display the protocol class-map configuration:
switch# show class-map class_protocol
Configuring QoS Group Classification
You can classify traffic based on the value of the QoS group internal label, that represents a system class.
You can set the value of the QoS group within a policy map using the set qos-group command.
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Creates a named object that represents a class of traffic.
Class-map names can contain alphabetic, hyphen, or
switch(config)# class-map type
{network-qos | queuing} class-name
Step 2
underscore characters, are case sensitive, and can be up
to 40 characters.
Configures the traffic class by matching packets based on
a list of QoS group values. Values can range from 0 to 5.
switch(config-cmap-que)# match
qos-group qos-group-value
Step 3
QoS group 0 is equivalent to class-default and QoS group
1 is equivalent to class-fcoe.
