System Forwarding

Packet Transfer Process

This section describes packet transfer process on the FW. It helps you better understand the configuration and maintenance rules.

Hardware Fast Forwarding

Enabling hardware fast forwarding can accelerate basic services, such as fast forwarding of subsequent packets, to improve the service performance of the device.

Status Check

The status check function allows the FW to check the validity of the link status in packets.

Session Tables

Server Map

A server map provides more flexibility than a session table and can match some traffic that cannot be matched by a session table.

Inner Tunnel Packet Detection

When the FW works in the Layer 2 transparency mode, it supports inner tunnel packet detection and establishes sessions based inner tunnel packet information.

Hash-based CPU Selection

Advanced Settings

Advanced settings affect the service of the FW. You must set global parameters correctly.

IP Performance

This section describes IP performance parameter concepts and how to configure the parameters.
