After the network data forwarding information is configured successfully, the network data forwarding of the gateway device can be realized to the switch on the basis of the configured network data forwarding information.
In this embodiment, network data forwarding information is configured, where the network data forwarding information is used to implement data access between the gateway device and the switch; after the network data forwarding information is configured, the network data of the gateway device is forwarded to the switch based on the network data forwarding information. Thus, through the configured network data forwarding information, the data access between the gateway equipment and the switch is effectively realized.
In some embodiments, configuring network data forwarding information includes:
initializing an intranet port and an extranet port; setting a data tag of an internal network port and a data tag of an external network port based on a preset communication protocol, wherein the data tag is used for describing port inlet and outlet indication information; configuring an IP address of an intranet port and an IP address of an extranet port; the working modes of the intranet port and the working modes of the extranet port are configured, wherein the working modes comprise: full duplex mode and half duplex mode.
The intranet port may be an uplink port, and is used as a processing interface of the internal network data. The external network port can be a downlink port and is used as a processing interface of external network data.

For example, the data tag of each internal network port and the data tag of each external network port may be set in a digital tag mode, when the digital tag is 1, the internal network port/external network port is determined to be a network data input port, and when the digital tag is 2, the internal network port/external network port is determined to be a network data output port.
When the IP address of the intranet port and the IP address of the extranet port are configured, the configuration may be implemented through custom configuration, for example, the IP address of the intranet port is set to 10.10.1.1, and the IP address of the extranet port is set to 10.10.1.2.
After the working modes of the internal network port and the external network port are configured, an adaptive adjusting control can be further set to start the adaptive adjusting control to carry out adaptive matching on the port working modes of the gateway equipment based on the mode configuration of the switch.

Wherein, "Link status: up" indicates that the ports are connected, "Link speed:2500Mbps" indicates that the connection speed is 2500Mbps, "Link duplex: full-duplex" indicates that the duplex mode is full duplex, "MTU:1500" indicates that the length of the data packet transmittable in the network is 1500 bytes, "Promitus mode: enabled" indicates that the Promiscuous mode is enabled.
The number of packets in the process of forwarding the network data of the gateway device to the switch may include: the transmission amount of network data and the reception amount of network data. Therefore, the forwarding condition of the network data can be effectively known by counting the number of packets and the type of the error packets in the process of forwarding the network data of the gateway equipment to the switch.

In other embodiments, configuring network data forwarding information includes:
mounting a first driver in a system of gateway equipment, wherein the first driver is used for describing a driving switch controller; the second driver is mounted and the MDIO tool is integrated into the second driver.
Wherein the first driver may be Marvell Unified Marvell SOHO Driver. The second driver may be Intel Ixgbe Driver, which provides a way for the user to directly access the switch (e.g., marvell Switch IC) registers from the Intel SOC (single chip microcomputer) by integrating the GPIO to MDIO tool into Intel Ixgbe Driver.
By modifying the DPDK TestPMD example, the operation of Intel Ixgbe Driver is changed from a kernel mode to a user mode by bypassing the characteristics of a kernel protocol stack and a driver, and the traffic of the exchange port is forwarded in high performance through the SOC by means of a program modified by the TestPMD.

Ko) and a fifth driver (such as dsa_bark. Ko) are both dependent on a sixth driver (such as phylink. Ko) to realize control of a physical interface.
