28. group membership information learned from IGMP a router switch can determine which if any multicast traffic needs to be forwarded to each of its ports At Layer 3 multicast routers use this information along with a multicast routing protocol such as DVMRP to support IP multicasting across the Internet Note that IGMP neither alters nor routes any IP multicast packets A multicast router switch must be used to deliver IP multicast packets across different subnetworks Class of Service CoS Support The TigerStack 100 provides two transmit queues on each port with a weighted round robin scheme This function can be used to provide independent priorities for various types of data such as real time video or voice and best effort data ADVANCED TOPICS Priority assignment to a packet in the TigerStack 100 can be accomplished in any of the following ways Priority can be explicitly assigned by end stations which have applications that require a higher priority than best effort This switch utilizes the IEEE 802 1p and 802 1Q tag structure to decide priority assignments for the received packets A port may be manually configured as high priority In this case when any other port receives traffic from a high priority port that traffic is automatically placed in the high priority output queue Port Trunks 4 8 Ports can be combined into an aggregate link to increase the bandwidth of a network connection or ensure fault recover
