Linksys SLM224G4S Specification Guide

Growing businesses require cost-effective, networking solutions that can scale with ever-

changing business needs. The Linksys SLM224G4S Smart Switch brings a whole new level 

of intelligence and security to the network infrastructure at a cost-effective price. It offers 24 

10/100 Ethernet (copper) ports with four 10/100/1000 Gigabit Ethernet copper or optional 

optical (SFP) interfaces for uplinking connected users to the core network.

Network security is a top priority in any size business; unauthorized access to the network 

and mission critical data is a constant concern.  The SLM224G4S is able to secure the network 

through 802.1X port authentication and MAC Filtering.  802.1X requires clients to authenticate 

themselves before the port will pass data.

The SLM224G4S switches provide resilient stacking for up to 6 units or 192 ports when 

combined with SLM248G4S. A stack of units is managed as a single switch with one Web 

Management interface to manage all the units. SLM224G4S can coexist in a stack with other 

Linksys Smart Stackable PoE and 24-port versions—SLM224G4PS, SLM248G4S, and SLM248G4PS.

Businesses are recognizing the benefits of Voice over IP (VoIP) phone calling and are quickly 

migrating their voice services to IP-based platforms, requiring their local area networks to support 

both voice and data applications. The SLM224G4S’s extensive QoS features make the solution ideal 

for real-time applications like Voice and Video. The four priority queues together with Weighted 

Round Robin and Strict Priority scheduling techniques let network administrators quickly prioritize 

real-time voice and video traffic over data traffic. Individual users or applications can also be 

prioritized above others using various Class of Service options—by port, Layer 2 priority (802.1p),  

and Layer 3 priority (TOS or DSCP). Intelligent Broadcast, Multicast, and Unknown Unicast storm 

control minimizes and contains the effects that these types of storms have on regular traffic. IGMP 

Snooping limits bandwidth-intensive video traffic to only the requestors without flooding to all users. 

Incoming traffic can be policed and outgoing traffic can be shaped allowing network administrators to 

control network access and traffic flow.

The SLM224G4S also includes features for network expansion and faster throughput performance. 

Link aggregation enables network administrators to create multiple high-bandwidth trunks between 

switches. This provides a level of reliability because the system will continue to operate if one of the links 

breaks. Spanning Tree (STP) and Fast Spanning Tree allow administrators to build a mesh of switches 

increasing the availability of the system.

The simplified user interface provides an intuitive, secure management platform enabling administrators 

to better utilize the comprehensive feature set of the switch, resulting in a better optimized, more secure 

network.
