Problems solved by technology

[0006] First, when the user inquires, it will mislead the user, because the port is in the open state, which means that data can be transmitted, but currently the data cannot be transmitted in the open state;
[0007] Second, if the link is single-passed, the opposite end of the slave port of the master node cannot detect a port fault, but the slave port of the master node can detect a link fault. In this case, if the slave port of the master node is released, the master node The node is also in the release state from the port to the end, then when the link is restored, there is no port blocking on the ring, and an instantaneous loop will be generated, causing a broadcast storm

Embodiment Construction

[0025] In the present invention, when the master node of the Ethernet ring network detects that the link directly connected to the slave port fails, no matter whether the ring network state before the fault of the slave port is detected is intact or faulty, the slave port will be blocked, and on the link During a fault, the blocked state remains.

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] As shown in Figure 4, the embodiment of the present invention includes the following steps:

[0028] Step 401, the master node detects the state of the direct link link from the port;

[0029] At present, there are many detection mechanisms to detect the link status. For example, the optical fiber can detect the optical signal, and if it cannot be detected, the link is considered to be faulty; If the detection packet sent by the end node is considered to be a link failure, etc.

Abstract

The utility model discloses a host node's sub-port failure processing method in the Ethernet system. The method examines the straight linkage status of the host node's sub-port; if the straight linkage status of the host node's sub-port does not work, the sub-port will be placed as the blocking state; during the period of link fault, the sub-port's blocking state shall be kept. The utility model avoids the port status error when the host node's sub-port in the Ethernet does not work, so as not to mislead the user and cause the broadcast storm. The utility model can be used for a plurality of Ethernet protection-related techniques.

Description

technical field [0001] The invention relates to the technical field of automatic protection of an Ethernet ring network, in particular to a fault handling method for a slave port of a master node of an Ethernet ring network system. Background technique [0002] The Ethernet ring network protection system in RFC3619 is composed of multiple nodes connected to form a ring, and multiple domains can be defined on the ring, that is, the Ethernet ring network protection domain. A domain includes a master node, several transit nodes, and a group of protected business virtual local area networks (VLAN, Virtual Local Area Network) for user data forwarding, where the two ports of the master node on the ring are respectively defined as master Ports and slave ports, the protected service VLAN is defined as the protected service VLAN. When the link on the ring is intact, the master node blocks the protection service VLAN forwarding function of the slave port, and there is no loop in the ...
