xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Last Hop SPT Switchover This field is used by the last hop router to decide whether to receive multicast data from the shared tree or switch over to the shortest path tree. When the switchover mode is set to never, the last hope router will always receive multicast data from the shared tree. When the mode is set to immediately, the last hop router will always receive data from the shortest path tree. Register Probe Time (1-127) This command is used to set a time to send a probe message from the DR to the RP before the Register Suppression time expires. If a Register Stop message is received by the DR, the Register Suppression Time will be restarted. If no Register Stop message is received within the probe time, Register Packets will be resent to the RP. The user may configure a time between 1 and 127 seconds with a default setting of 5 seconds. Register Suppression Time (3-255) This field is to be configured for the first hop router from the source. After this router sends out a Register message to the RP, and the RP replies with a Register stop message, it will wait for the time configured here to send out another register message to the RP. The user may set a time between 3 and 255 with a default setting of 60 seconds. Click Apply to implement changes made. NOTE: The Probe time value must be less than half of the Register Suppression Time value. If not, the administrator will be presented with an error message after clicking Apply.
