for the N8500 device, after customer configure the function of Event Notification, when they send a test mail, the system report ‘Unable to receive the management message’
Unable to receive the management message
we can change the cluster name to a required length on the ISM system
we collect and analyze the system logs and find that the alarm infortion is reported by the agent in the system. after we check the agent log, we find that the problem is caused by the long cluster name which exceed the required length. the required length is 10 charactors, but customer's cluster name length is 12. so for the invalid cluster name information in the mail notification function, when customer send a test mail, system will report the alarm.
prepare to learn the detail information about the function which you want to use first to avoid the mistake.
