Usage Guidelines

Usage Scenario

Traditional traffic classification technologies only check the content at Layer 4 and lower layers in packets, for example, source IP address, destination IP address, source port number, destination port number, and service type. It cannot analyze applications in packets. SA is a traffic detection and control technology based on the application layer. Apart from the IP packet header, SA can analyze the content of the application layer.

To identify the application of the traffic passing through an interface, run the service-awareness enable command to enable SA on the interface.

Prerequisites

The resource allocation mode has been set to sac for the slot corresponding to the interface. To check the current resource allocation mode of the switch and the resource allocation mode specified using the assign resource-mode command, run the display resource-mode configuration command. If the resource allocation mode is not sac, run the assign resource-mode sac command to change the resource allocation mode to sac, save the configuration, and restart the switch.

Example

# Enable SA on VLANIF 10.

<HUAWEI> system view
[HUAWEI] vlan batch 10
[HUAWEI] interface vlanif 10
[HUAWEI-Vlanif10] service-awareness enable
