Here are somepossible failures you might meet and the corresponding troubleshooting methods.I. Symptom 1: Frequent prompts of configuration errors on the consoleThis indicates that incorrect VRRP packets have been received. It may be because ofthe inconsistent configuration of another switch within the virtual router, or the attemptsof some devices to send out illegal VRRP packets. The first possible fault can be solvedthrough modifying the configuration. And as the second possibility is caused by themalicious attempt of some devices, non-technical measures should be resorted to.II. Symptom 2: More than one Master existing within the same virtual routerThere are also 2 reasons. One is short time coexistence of many master switches,which is normal and needs no manual intervention. Another is the long timecoexistence of many Master switches, which may be because switches in the virtualrouter cannot receive VRRP packets from each other, or receive some illegal packets.To solve such problems, an attempt should be made to ping the master switches. Ifsuch an attempt fails, check the device connectivity. If they can be pinged, check the
