It is to be understood that although the terms first, second, third, etc. may be used herein to describe various information in the embodiments of the present disclosure, such information should not be limited by these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

The disclosure provides a port redundancy processing method and device, an electronic device and a machine-readable storage medium, so as to solve the problem that the switching of a main device and a standby device is not smooth.
Specifically, the technical scheme is as follows.
In an embodiment, the present disclosure provides a port redundancy processing method, applied to a network device having multiple interfaces, where at least two interfaces are respectively connected to devices having a primary/standby relationship therebetween, the method including: establishing a redundant port, and associating interfaces which are respectively connected with service equipment with a main-standby relationship to the redundant port; setting an interface connected with the main service equipment as an activation interface of a redundant port, forwarding a message received from the redundant port to the activation interface, and forwarding the message received from the activation interface from the redundant port to next hop equipment; and switching the activation interface according to the current equipment state, and setting the interface connected with the current main service equipment as the activation interface of the redundant interface.
Specifically, as shown in fig. 1, the method comprises the following steps:
step S11, setting a redundant port, and associating interfaces respectively connected with service devices with a main-standby relationship to the redundant port;
step S12, setting an interface connected with the main service equipment as an activation interface of a redundant port, forwarding a message received from the redundant port to the activation interface, and forwarding the message received from the activation interface from the redundant port to next hop equipment;
and S13, switching the activation interface according to the current equipment state, and setting the interface connected with the current main service equipment as the activation interface of the redundant interface.
When the external device and the service device perform message interaction, the learned ports of the service device are all redundant ports, and when the master-slave switching of the service device occurs, the switch serving as the network device only needs to switch the corresponding interface in the associated interfaces of the redundant ports to be an active interface according to the situation, so that the master-slave switching of the service device can be completed under the condition that the external device does not sense the switching, and the switching is smooth.
In an embodiment, the switching the active interface according to the current device status, and setting the interface connected to the current main service device as the active interface of the redundant port includes: and if the current equipment state is that the original main service equipment is off-line, the original main service equipment is switched to new main service equipment, the LLDP message sent by the new main service equipment is received, and an interface connected with the new main service equipment is set as an activation interface of the redundant port according to the LLDP message.
In an embodiment, the switching the active interface according to the current device state, and setting the interface connected to the current main service device as the active interface of the redundant port includes: if the current equipment state is the activated interface failure, the original service equipment is informed to be switched to the new main service equipment, and the interface connected with the new main service equipment is set to be the activated interface of the redundant port.

Two-layer interfaces of the uplink switch and the firewall are added into the two-layer redundant interface. When the service equipment A is main equipment, the port A1 of the service equipment A sends an LLDP message to inform an uplink switch, the interface 1 connected with the service equipment A in the redundant port is an activated interface, and after receiving the message, the switch selects the interface 1 to send when sending the message. When the firewall master and standby are switched, the port B1 of the service device B sends an LLDP message, notifies the upstream switch, the interface 2 in the redundant port is an active interface, and the switch receives the message and sends the selected interface 2 when sending the message.
In the redundant interface mode, the switch learns the MAC on the redundant interface in a unified way, and when the service equipment switches between the main service equipment and the standby service equipment, the switch only needs to replace the message sending interface.
When the switch side is out of order and needs to switch, it can also send LLDP message to the service device to inform it actively, and when the service device receives the inform message, it can also switch actively, thus realizing bidirectional interaction and further improving the reliability of the network. Meanwhile, the LLDP notification message can inform the opposite terminal of the switching reason of the local terminal, so that the maintainability of the whole network is greatly improved.
The service device may be a firewall device or other devices meeting actual use requirements.
