Chapter 1: Introduction
Overview
The ES3628EA 24 10/100 Ports + 4G L2/L3/L4 Intelligent Switch has 24
100BASE-TX ports, 2 1000BASE-T ports, and 2 SFP transceiver slots. There is also
an SNMP-based management agent embedded on the main board. This agent
supports both in-band and out-of-band access for managing the switch.
This switch can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly
performing networks by segregating them into separate broadcast domains with
IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast
switching and CoS services, and eliminates conventional router bottlenecks.
It can be used to augment or completely replace slow legacy routers,
off-loading local
IP traffic to release valuable resources for non-IP routing or WAN access. With
wire-speed performance for Layer 2 and Layer 3, this switch can significantly
improve the throughput between IP segments or VLANs.

Switch Architecture
The ES3628EA employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all ports.
This switch also features full-duplex capability on all ports, which effectively doubles
the bandwidth of each connection.
Switching Method
For communications within the same VLAN, the switch uses store-and-forward
switching to ensure maximum data integrity. With this type of 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.
For communications between different VLANs, the switch also performs
