Command Manual – System Maintaining and DebuggingH3C S3610&S5510 Series Ethernet Switches Chapter 3 Device Management Commands3-223.1.20 shutdown-intervalSyntaxshutdown-interval timeViewSystem viewParameterstime: Detection interval in seconds, in the range of 1 to 300.DescriptionUse the shutdown-interval command to set a detection interval.By default, the detection interval is 30 seconds.Note that:z If a protocol module such as the operation, administration and maintenance (OAM)module detects an exception on a port (for example, signal loss of the link on thepeer end), the port will be closed automatically, without execution of theshutdown command. You can set the automatic recovery time of the port by usingthe shutdown-interval command.z The shutdown-interval command helps you to dynamically set a detectioninterval to cooperate with the OAM module.z If you change the detection interval to T1 during interface detection, the intervalfrom when you change the interval to the time when detection starts is T. If Tthe interface which is down will be brought up after T1-T time; if T>=T1, theinterface which is down will be brought up immediately.Examples# Set the detection interval to 100 seconds. system-view[Sysname] shutdown-interval 100
