Abstract

The invention discloses a method and device for switching an overtime period, and communication equipment. When a transmission link between first communication equipment and second communication equipment has other communication equipment, the first communication equipment can switch a long overtime period into a short overtime period, thereby improving the link detection efficiency, and timely carrying out the corresponding processing to reduce the cutoff time of the communication equipment when the transmission link has an accident. The method comprises the steps that the first communication equipment determines whether the transmission link between the first communication equipment and the second communication equipment has third communication equipment or not; the first communication equipment enables the overtime period for detecting the transmission link to be switched to a second overtime period from a first overtime period when the transmission link has third communication equipment, wherein the first overtime period is greater than the second overtime period.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a method, device and communication device for switching timeout time. Background technique [0002] Link aggregation (Link Aggregation, referred to as "LA") refers to a method of bundling a group of physical ports together as a logical interface to increase bandwidth. For related protocol standards, please refer to IEEE802.1AX. By establishing a link aggregation group (Link AggregationGroup, referred to as "LAG") between two communication devices, higher communication bandwidth and higher reliability can be provided, and this improvement does not require hardware upgrades, and also Redundant protection is provided for the communication of two communication devices. Between the two communication devices, configure LAG in the Link Aggregation Control Protocol (LACP packet for short) mode. After the LACP packet protocol negotiation is successful, keep-alive p...
