High-Performance and High-

Availability 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-config-

ures, 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 con-

verged 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

Weighted Round Robin (WRR) Queuing is supported. Support for the IP Differentiated Services Code Point (DSCP) enables the switches to enforce requested service levels.
