Extreme Networks A4 is a highly reliable fast Ethernet edge switch that delivers scalable wire-speed performance to support today

Bandwidth intensive and latency requirements for demanding applications. A4 also provides multi-layer packet classification and priority queuing for differentiated services. except

In addition to the 17.6 Gbps switch capacity, the A4 offers up to 48 10/100 Ethernet ports and four Gigabit Ethernet uplink ports.

Leveraging the stacking capabilities of the A4, up to eight A4s can be interconnected in a single stack to create a virtual switch that delivers 140.8 Gbps

Capacity and up to 384 10/100 Ethernet ports as well as 16 Gigabit Ethernet uplink ports.

The main functions of the switch include physical addressing, network topology, error checking, frame sequence and flow control. When the destination address of a data frame is mapped in the MAC address table, it is forwarded to all ports connected to the destination node (if the data frame is a broadcast/multicast frame, all ports are forwarded). When a switch includes a redundant loop, the Ethernet switch uses the spanning tree protocol to avoid the loop and allow for a backup path. When the destination address of a data frame is mapped in the MAC address table, it is forwarded to all ports adjacent to the destination node (if the data frame is a broadcast/multicast frame, all ports are forwarded).
