Operation Manual – Auto DetectH3C S5600 Series Ethernet Switches Chapter 1 Auto Detect Configuration1-1Chapter 1 Auto Detect ConfigurationWhen configuring the auto detect function, go to these sections for information you areinterested in:z Introduction to the Auto Detect Functionz Auto Detect Configurationz Auto Detect Configuration Examples1.1 Introduction to the Auto Detect FunctionThe Auto Detect function uses ICMP request/reply packets to test network connectivityregularly.The detected object of the Auto Detect function is a detected group, which is a set of IPaddresses. To check the reachability to a detected group, a switch enabled with AutoDetect sends ICMP requests to the group and waits for the ICMP replies from the groupbased on the user-defined policy (which includes the number of ICMP requests and thetimeout waiting for a reply). Then according to the check result, the switch determineswhether to make the applications using the detected group take effect.Currently, the following features are used in conjunction with Auto Detect:z Static routez Virtual Router Redundancy Protocol (VRRP)z Interface backupNote:z A detected group can be used by multiple applications simultaneously.z For details about static routing, refer to the Routing Protocol part of the manual.z For details about VRRP, refer the VRRP part of the manual.1.2 Auto Detect ConfigurationComplete the following tasks to configure auto detect:Task RemarksAuto Detect Basic Configuration RequiredAuto Detect Implementation in Static Routing Optional
