High performance, high density — Up to 384 10/100 ports 16 gigabit uplinks in a single stack • High-availability services — IEEE 802.3ad Link Aggregation — Ethernet Flow Control — IGMP snooping v1 & v2 — Closed Loop Stacking — Optional redundant power — Redundant stack management • Advanced Quality of Service — Extensive traffic classification capabilities — Ingress rate limiting — Extensive VLAN support • Sophisticated Security — IEEE 802.1x Authentication — SSH and RADIUS SecureStack A2 Switch Family • High-density, high-availability stackable 10/100 switching • Closed-loop redundant stacking to assure continuous stack operation • QoS support for VoIP and real-time broadcast/multicast • Power-over-Ethernet models available • Complete stack management via NetSight®, Web or CLI High-Performance and HighAvailability Stacking The SecureStack A2 stackable switch family delivers cost-effective Layer 2 switching in a single stack with up to 384 10/100 ports with 16 gigabit uplinks. Reliability and availability is assured with support for Closed Loop Stacking, redundant core connections, redundant power options and redundant stack management. Each SecureStack A2 switch has two mini-GBIC (SFP) ports and two fixed 10/100/1000 ports that can be used as standard Ethernet uplinks but can also be used as stacking ports that support up to 2 Gbps of bi-directional bandwidth between any two adjacent switches. No additional stack module is required to stack the switches. A single stack can be comprised of any combination of SecureStack A2 switches allowing a mixture of 24- and 48-port 10/100, 100Base-FX and Power-over-Ethernet ports to be linked to the network core via copper, multimode fiber and/or single-mode fiber Gigabit. Closed Loop Stacking is implemented, which assures that a single switch or cable connection failure in the stack will not impact the overall stack operation. The SecureStack A2 stack auto-configures, allowing stack switch units to be added or removed with minimal p a c k e t interruption. Up to eight SecureStack A2 switches can be supported in a stack with a single IP address for complete stack management. Redundant s t a c k management is supported by a s s i g n i n g a primary and multiple secondary stack managers. Switching Services All SecureStack A2 switches support standards-based switching. The IEEE standards for switching (IEEE 802.1D MAC Bridges) and IEEE 802.1t (802.1D Maintenance), as well as Multiple Spanning Trees (IEEE 802.1s) and Rapid Reconvergence (IEEE 802.1w), are fully supported. All switches support up to 8,000 addresses and have four hardware queues per port. Ethernet Flow Control (IEEE 802.3x) as well as standards-based Link Aggregation (IEEE 802.3ad) are fully supported in every switch model. In addition, all switches support IGMP Snooping v1 and v2. Traffic Classification and QoS A major component for supporting converged networks is traffic classification. All SecureStack A2 switches deliver Layer 2/3/4 packet classification and marking at the edge based on any of the following: • MAC address • Physical port • IP address • IP protocol • IP ToS/DSCP marking • TCP/UDP port • IP subnet
