Embodiment 1

[0060] In this embodiment, the cascade aggregation port 111 of the CB device 110 recovers after an exception occurs as an example.

[0061] Such as Figure 3A and Figure 3B As shown, the online control method provided in this embodiment may include the following steps:

[0062] Step 301, the CB device 110 recovers after detecting that the cascade aggregation port 111 is abnormal, and queries the state of the PE device 210 recorded by itself;

[0063] Step 302, when the state of the PE device 210 recorded by the CB device 110 is offline, the CB device 110 starts a timer;

[0064] Wherein, if the CB device 110 inquires that the status of the PE device 210 is online, the process ends directly.

[0065] Step 303, when the timer expires, query the state of the PE device 210 recorded by itself again; if it is offline, then go to step 304; otherwise, end the current process;

[0066] In this embodiment, if the PE device 210 perceives the state change of the cascaded aggregation ...

Embodiment 2

[0073] In this embodiment, it is taken as an example that the cascade aggregation port 123 of the CB device 120 recovers after an abnormality occurs.

[0074] Such as Figure 4A and 4B As shown, the online control method provided in this embodiment may include the following steps:

[0075] Step 401, the CB device 120 recovers after detecting that the cascade aggregation port 123 is abnormal, and queries the state of the PE device 230 recorded by itself;

[0076] Step 402, when the state of the PE device 230 recorded by the CB device 120 is offline, the CB device 120 starts a timer, and sets the timing duration to 3 minutes;

[0077] Wherein, if the CB device 110 inquires that the status of the PE device 210 is online, the process ends directly.

[0078] Step 403, the CB device 120 counts the number of times the cascade aggregation port 123 recovers after an abnormality occurs within 3 minutes, and when the number of times the cascade aggregation port 123 recovers after an a...

Abstract

The present invention provides an expansion network bridge and an online control method thereof. The method includes: when a cascade aggregation port connected to a port expansion device on the control bridge device recovers after an exception occurs, querying the port expansion device recorded by itself When the state of the port expansion device recorded by itself is the offline state, an online notification message is sent to the port expansion device to trigger the port expansion device to go online. The application of the present invention can improve service reliability.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an extended network bridge and an online control method thereof. Background technique [0002] 802.1BR is an application-level protocol at the access level of the data center. It defines the operation, interaction protocol, management objects and algorithms of the extended bridge, and can provide the multi-port expansion capability of the bridge for multiple physical server connections and blade servers. Or provide an independent bridge interface for the virtual machine to realize the logical connection. [0003] The extended network bridge is a technical implementation based on the 802.1BR protocol. On the basis of forming a logical virtual device, a box device is added to the main device system as a remote interface board to achieve extended I / O (Input / output, input / output) port capabilities and the purpose of centralized control and management. [0004] The de...
