Chapter 1: Introduction

Overview

The MR2228-S2C switch is a stackable Fast Ethernet switch with 24

10BASE-T/100BASE-TX ports and two 1000BASE-T ports that operate in

combination with two Small Form Factor Pluggable (SFP) transceiver slots. The

switch also provides two 1 Gbps built-in stacking ports for connecting up to eight

units in one stack. The stacking ports can also be used as normal Ethernet ports

in standalone mode. The MR2228-S2C also includes an SNMP-based

management agent, which provides both in-band and out-of-band access for

managing the switch.

The MR2228-S2C provides a broad range of powerful features for Layer 2

switching, delivering reliability and consistent performance for your network traffic.

It brings order to poorly performing networks by segregating them into separate

broadcast domains with IEEE 802.3Q compliant VLANs, and empowers

multimedia applications with multicast switching and CoS services.

Switch Architecture

The MR2228-S2C employs a wire-speed, non-blocking switching fabric. This

permits simultaneous wire-speed transport of multiple packets at low latency on

all ports. The switch also features full-duplex capability on all ports, which

effectively doubles the bandwidth of each connection.

The switch uses store-and-forward switching to ensure maximum data integrity.

With store-and-forward switching, the entire packet must be received into a buffer

and checked for validity before being forwarded. This prevents errors from being

propagated throughout the network.

The switch includes built-in stacking ports that enable up to eight units that can

be connected together through a 1 Gbps stack backplane. The switch stack can

be managed from a master unit using a single IP address.
