CONFIGURING THE SWITCH
adjacent multicast switch/router to ensure that it will continue to receive the multicast service.
Note: Multicast routers use this information, along with a multicast routing protocol such as DVMRP or PIM, to support IP multicasting across the Internet.
Command Attributes
•IGMP Status — When enabled, the switch will monitor network traffic to determine which hosts want to receive multicast traffic. This is also referred to as IGMP Snooping. (Default: Disabled)
•IGMP Query Count — Sets the maximum number of queries issued for which there has been no response before the switch takes action to drop a client from the multicast group.
(Default: 2, Range: 2 - 10)
•IGMP Report Delay — Sets the time (in seconds) between receiving an IGMP Report for an IP multicast address on a port before the switch sends an IGMP Query out of that port and removes the entry from its list. (Default: 10, Range: 5 - 30)
•Query Timeout — The time the switch waits after the previous querier stops before it considers the router port (i.e., the interface which had been receiving query packets) to have expired. (Default: 300 seconds, Range: 300 - 500)
•IGMP Version — Sets the protocol version for compatibility with other devices on the network. (Default: 2, Range: 1 - 2)
Notes: 1. All systems on the subnet must support the same version.
2.Some attributes are only enabled for IGMPv2, including IGMP Report Delay and IGMP Query Timeout.
