IGMP Filtering and Throttling

â—† When receiving an IGMPv3 report message, the switch will send the access
request to the RADIUS server only when the record type is IS_EX
(MODE_IS_EXCLUDE) which excludes a source list, or TO_EX
(CHANGE_TO_EXCLUDE_MODE), and the source list is empty. Other type of
packets will not be authenticated.
â—† The first time the report is received and is being authenticated, regardless of
whether the authentication result succeeds or fails, this report will still be sent
to any configured multicatst router port.
â—† The attribute value pairs configured on the RADIUS server are shown below.
