7.6.2 Packet Classification
Packet classification features allow traffic to be partitioned into multiple priority levels, or
classes of service. In Flow Configuration mode, you can set packet classification criteria
via flow, which is with unique name. If you specify the value of parameters, this switch
classifies the packets corresponding to the parameters.
7.6.2.1 Flow Creation
The packet classification involves a traffic descriptor to categorize a packet within a spe-
cific flow for QoS handling in the network. You need to open Flow Configuration mode first
to classify the packets. To open Flow Configuration mode, use the following command.
Command Mode Description
flow NAME create Global
Creates a flow and opens Flow Configuration mode.
NAME: flow name.
After opening Flow Configuration mode, the prompt changes from SWITCH(config)# to
SWITCH(config-flow[NAME])#.
To delete configured Flow or all Flows, use the following command.
Command Mode Description
no flow NAME Deletes specified flow.
no flow all
Global
Deletes all flows.
After opening Flow Configuration mode, a flow can be configured by user. The packet
classification can be configured for each flow.
• The flow name must be unique. Its size is limited to 32 significant characters.
• The flow name cannot start with the alphabet “a” or “A”.
• The order in which the following configuration commands are entered is arbitrary.
• The configuration of a flow being configured can be changed as often as wanted
until the apply command is entered.
• Use the show flow-profile command to display the configuration entered up to now.
You cannot create the flow name which started with alphabet ‘a’ If you try to make a flow
name started with alphabet ‘a’, the error message will display.
7.6.2.2 Configuring Flow
The packet classification criteria needs to be defined. You can classify the packets via
MAC address, IP address, Ethernet type, CoS, DSCP etc.
