IGMP filtering (controlling multicast distribution) > Example

XConfigure switch 1

Switch 1—the closest switch to the multicast source—is an IGMP Querier. The filter is configured on it, as shown in bold in the script below.

Note that the order of entries in a filter is important. When IGMP tries to match a message to a filter, it performs a linear search of the filter to find a matching entry, starting with the lowest-numbered entry. It stops processing the filter at the first match it finds. Therefore, this filter has an entry with one multicast group and an action of exclude, followed by an entry with all multicast groups and an (implicit) action of include.

Different Also note that in software versions 2.8.1 and later, each entry filters only one type of IGMP message message. To control the type of message, use the msgtype parameter in the following

types command:

add igmp filter=filter-idgroupaddress={ipaddipadd-ipadd} [entry=1..65535] [action={includeexclude}] [msgtype={query reportleave}]

In software version 2.8.1, this parameter is mandatory. Since software versions 281-01 and 2.9.1, the parameter is optional with a default of report. In this example we are filtering Reports, so we do not need to specify the message type.
