9. A packet received by the NI MES 3980 may or may not have an 802 1p tag associated with it If it does not then it is given a default 802 1p tag which is usually 0 Alternatively the packet may be marked with a new 802 1p value which will result in all knowledge of the old 802 1p tag being lost 3 33 NI MES 3980 User s Manual Featured Functions 2 As the 802 1p priority levels are fixed to the traffic queues the packet will be placed in the appropriate priority queue ready for transmission through the appropriate egress port When the packet reaches the head of its queue and is about to be transmitted the device determines whether or not the egress port is tagged for that VLAN If it is then the new 802 1p tag is used in the extended 802 1D header The NI MES 3980 will check a packet received at the ingress port for IEEE 802 1D traffic classification and then prioritize it based upon the IEEE 802 1p value service levels in that tag It is this 802 1p value that determines to which traffic queue the packet is mapped Traffic Queues The NI MES 3980 hardware has multiple traffic queues that allow packet prioritization to occur Higher priority traffic can pass through the NI MES 3980 without being delayed by lower priority traffic As each packet arrives in the NI MES 3980 it passes through any ingress processing which includes classification marking re marking and is then sorted into the appropriate queue The switch then forw

31. 4 VLAN settings Using Multicast Filtering Multicast filtering improves the performance of networks that carry multicast traffic This section explains multicasts multicast filtering and how multicast filtering can be implemented on your NI MES 3980 The Concept of Multicast Filtering What is an IP Multicast A multicast is a packet sent by one host to multiple hosts Only those hosts that belong to a specific multicast group will receive the multicast If the network is set up correctly a multicast can only be sent to an end station or a subset of end stations on a LAN or VLAN that belong to the multicast group Multicast group members can be distributed across multiple subnets so that multicast transmissions can occur within a campus LAN or over a WAN In addition networks that support IP multicast send only one copy of the desired information across the network until the delivery path that reaches group members diverges To make more efficient use of network bandwidth it is only at these points that multicast packets are duplicated and forwarded A multicast packet has a multicast group address in the destination address field of the packet s IP header 3 43 NI MES 3980 User s Manual Featured Functions Benefits of Multicast The benefits of using IP multicast are that it Uses the most efficient sensible method to deliver the same information to many receivers with only one transmission e Reduces the load on the source
