Embodiment Construction

[0033] Aiming at the above-mentioned problems existing in the prior art, the embodiment of the present invention provides a port mode synchronization scheme between devices, by sending ordinary Ethernet packets as mode switching request messages from the Fabric port of the device to request the peer device The corresponding interconnection port of the corresponding interconnection port is switched to the Fabric mode, so as to realize the synchronization of the Fabric mode of the interconnection port between devices, solve the problem of automatic detection and negotiation between the Fabric port and the common Ethernet port, and improve the convenience of forwarding Fabric packets.

[0034] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] The following takes device A and device B as examples, combining figure 2 , detailing the port mode synchronization scheme between network devices. In order to real...

Abstract

The invention discloses a method, device, and system for synchronizing port modes between devices. After the interconnecting ports of two devices are interconnected and the interconnecting port of one of the two devices is configured in an interconnection Fabric mode, the method comprises that the device with the interconnecting port configured in the Fabric mode transmits a mode switching request message to an opposite-end device with an interconnecting port configured in an Ethernet mode; and that according to a message sign carried in the mode switching request message, the opposite-end device switches the interconnecting port of the opposite-end device from the Ethernet mode to the Fabric mode and returns the mode switching request message. The method resolves a problem of incapable automatic negotiation between the Ethernet port and the Fabric port of devices and automatically switches the interconnecting port of the device from the Ethernet mode to the Fabric mode so as to achieve normal reception and analysis of Fabric messages and improve convenience for forwarding the Fabric messages.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a method, device and system for synchronizing port modes between devices. Background technique [0002] In a stacking system, devices need to be connected to each other, and packet forwarding between devices is implemented through the interconnection ports between devices. All mainstream commercial chips support adding a layer of Header (message header) to forward messages between chips to form Fabric messages. Due to the newly added header, the normally forwarded packets become longer and occupy a certain amount of bandwidth. In order to minimize the bandwidth occupation, for example figure 1 As shown, the Header of some chips will occupy 8 bytes of preamble and 4 bytes of IPG (Interpacket Gap). [0003] The switch chip specifies the chip interconnection port as a Fabric port through the configuration register, which is used to forward packets encapsulated with ...
