Network traffic classification

Network classification and identification occurs by adding a rule that classifies the network traffic as a particular network type.

Each of the rules is a set of network details that is used to filter and classify the network traffic. You can define a rule by providing the following information to classify the network traffic:

Traffic type (required)

The traffic type choices depend on your deployment model. For example, in the In-path double point (LAN optimized) deployment model you are expected to classify only two types of the network traffic: the WAN traffic on the WAN side and the LAN optimized traffic on the LAN side. This choice of deployment model limits the traffic type options to WAN and LAN Optimized. The advanced mode deployments contain all available traffic types:

  • WAN
  • LAN Optimized
  • Datacenter LAN
  • Drop

Name (optional)

Common name or description for this network.

Interface (optional)

List of interfaces available for network classification.

VLAN (optional)

VLAN tag.

If the No VLAN in traffic check box is selected, observed network traffic does not contain VLAN traffic. It forces all observed VLAN packets NOT to be automatically recognized as VLAN.

MPLS (optional)

Label of an MPLS-based network.

If the No MPLS in traffic check box is selected, observed network traffic does not contain MPLS traffic. It forces all observed MPLS packets NOT to be automatically recognized as MPLS.

GRE/WCCP (optional)

Generic Routing Encapsulation (GRE) /Web Cache Communication Protocol (WCCP) identification.

Enter the WCCP System ID that is running in GRE tunnel. The Dynamic service identifier can be a number from 0 to 254 and can be obtained from your router by running the show ip wccp command at the router's command prompt. Select the check box when your traffic does not use WCCP in GRE tunnel.

If the No GRE/WCCP in traffic check box is selected, observed network traffic does not contain GRE/WCCP packets. It forces all observed GRE/WCCP packets NOT to be automatically recognized as GRE/WCCP.

Direction (available and required only for Cisco deployments)**

Direction of the observed traffic to be classified. For example, it is possible to create two network traffic classifications of the same network traffic containing the same VLAN tag. Traffic going To Server is classified as WAN while the same VLAN traffic going From Server can be classified as Datacenter LAN.

Available options are:

  • Both
  • From server
  • To server
