Classifying According to the Layer 5 Byte

Software Version 2.7.5 enables you to create classifiers that match specific bytes

in the Layer 5 part of IP packets. Layer 5 is the Layer 4 payload, so the new

classifier parameters match parts of the TCP or UDP payload. The switch can

perform its full array of hardware filtering and Quality of Service actions on

matched traffic.

The flexibility of this classifier option means you can match the traffic you need

to, even new protocols. You are not limited to pre-defined protocol options.

This enables you to isolate new network attacks and peer-to-peer applications

for network protection, monitoring and access control.

To create the classifier, use the new l5byte parameters in the create classifier or

set classifier commands.

The following table summarises the modified commands (see Command

Reference Updates).
