Use the command...Clear routeentries from thecore multicastrouting tablereset multicast routing-table { all | { group-address [ mask{ group-mask | group-mask-length } ] | source-address [ mask{ source-mask | source-mask-length } ] | incoming-interfacevlan-interface interface-number } * }The corresponding MFC forwarding entries are cleared when routing entries arecleared from the core multicast routing table.1.2.5 Configuring Broadcast/Multicast SuppressionTo prevent port congestion resulting from broadcast/multicast packet flooding, theswitch supports broadcast/multicast suppression. You can enable broadcast/multicastsuppression by setting the speed percentage or bandwidth values.Follow these steps to configure broadcast/multicast suppression:To do... Use the command...
