Switch with 2 Combo SFPs
Cost-effective, secure switching with
simplified management for your
growing business
The new Linksys Business Series Smart Ethernet Switches are cost-effective switching
solutions ideal for small businesses, the network edge, or workgroups within larger
organizations. These easy-to-install, high-speed switches offer many of the same Quality
of Service and Security features found in more expensive full Layer 2 managed switches
but without their complexity. The SLM224G offers twenty-four (24) 10/100 Copper ports
with two (2) shared Gigabit copper or optical (SFP) uplink interfaces for connecting
the switch to the core network. The SLM224G’s simplified user interface is an intuitive
management tool enabling you to quickly utilize the comprehensive feature-set of the
switch, resulting in a better optimized network.
Quality of Service—The SLM224G includes numerous QoS features to ensure that traffic is
prioritized properly to deliver the best possible user experience for real time applications
like voice and video or bandwidth intensive graphic/video file uploads or downloads. With
its IGMP Snooping feature, the SLM224G limits IP multicast traffic (real time presentations,
videoconferences, on-line gaming) to only the ports that have requested it enabling the
rest of the network to operate at peak efficiency. Additional QoS capabilities like IEEE
802.1p Priority Tagging, DSCP (Differentiated Services Code Point), and 4 hardware queues
also maintain quality for real-time applications like voice and video. Network traffic can be
optimized with the switch’s 802.1Q VLAN (Virtual LAN) support which enables you to quickly
segregate network traffic by department or workgroup. VLANs also provide an additional layer
of security by keeping sensitive data separated from other workgroups on the network.
Network Security is an absolute requirement for any business and preventing unauthorized
access to the company network is business-critical. The SLM224G secures the network through
802.1X port authentication which prompts end-users to provide their username and password
before they are permitted to pass data. User access can also be controlled through the SLM224G’s
MAC-Based Filtering capability which allows network access only to those devices or workstations
that have been authorized as identified by their MAC (Media Access Control) address. The Many-
to-One or One-to-One Port Mirroring feature of the SLM224G enables you to monitor the type of
traffic being transmitted on the network.
Quick, foolproof network expansion—
The SLM224G includes features for quickly expanding and
growing your network. To substantially increase network throughput speeds, especially useful for
companies whose employees are routinely backing up their hard drives to a company server or
storage platform, the SLM224G supports Link Aggregation which allows multiple high-bandwidth
trunks between switches to be set up. Link Aggregation also provides a level of availability and
redundancy as traffic will continue to flow even if one of the network links break. The SLM224G’s
Spanning Tree Protocol support (STP) and Storm Control features help to control planned or inadvertent
cable loops when switches are connected to one another. These loops can cause broadcast or multicast
storms in the network and severely limit its performance. With these features, you can confidently build a
mesh of switches and quickly expand your network to support your growing workforce.
