The A4 also integral network security SUPPORT AND SERVICE • Industry-leading customer satisfaction and first call resolution rates • Personalized services, including site surveys, network design, installation, and training • Comprehensive lifetime warranty, including feature upgrades and more • Release 6.61 adds policy and basic routing with support for two devices (PC and a phone) on a single port Product Overview provides scalable, wire-rate performance in support of the bandwidth-intensive provides multi-layer packet classification and priority queuing for differentiated services. Along with a switch capacity of 17.6 Gbps, the A4 provides up to 48 10/100 Ethernet ports as well as 4 Gigabit Ethernet uplink ports. Leveraging the A4’s stacking capability, as many as 8 A4s can be interconnected in a single stack to create a virtual switch that provides 140.8 Gbps of capacity and up to 384 10/100 Ethernet ports as well as 16 Gigabit Ethernet uplink ports. The A4 includes enterprise-class features in a 10/100 stackable switch that ensure seamless connectivity and application performance. With support for 16,000 MAC addresses, the A4 is an excellent choice for medium to large enterprises that need to support thousands of endpoints. Support for Extreme Networks policy enables strong support for integrated multimedia networks, including Voice over IP (VoIP) and IP video, as well as all types of data-intensive applications. With the 6.61 firmware release, all A4s can now deploy separate policies for both a personal computer and a VoIP phone on a single switch port. In conjunction with its nonblocking L2 switching architecture, the A4’s intelligent queuing mechanisms ensure that mission-critical applications receive prioritized access to network resources.
