4 4 1 1 Configuratio n > IG MP Snooping With Internet Group Ma nagement Protoc ol (IGMP) s nooping, the Web-Smart Switch can make intellig ent multicast forwarding decisions by e xamining the conten ts of each frame’s La yer 2 MAC hea der. IGMP snoopi ng can hel p reduce cluttered traffi c on the LAN .
4 4 2 2 Query Interval (60-600 sec): The Query I nterval is the interv al between Ge neral Queries sent. By adjusting the Quer y Interval, the number of IGMP messa ges can incr ease or decrease; larger values cause IGMP Queries to be sent le ss often.
4 4 3 3 Router Timeout (60-600 sec): This is the interval after w h ich a learnt router port entry will be purg ed. For each rou ter port learnt, a 'RouterPortPur geTimer' ru ns for ' RouterPort PurgeInte rval'. This timer will be restarted whenever a router control message is received over that port.
