Configuration Using the

Web-based Utility

This chapter describes the features included in the Web-based Utility. All features shown in this chapter, unless specifically identified, are included in all Resilient Clustering Smart Switches. Unique features for specific Switches are noted.

NOTE: The web-based utility is optimized for

ascreen resolution of 1024 x 768. Internet Explorer version 5.5 or above is required.

To use the utility, open your web browser, enter http://192.168.1.254 in the Address field, then press Enter.

Address Bar

NOTE: The default IP address is 192.168.1.254. If you have changed the IP address or are using DHCP to assign it, enter the new IP address instead. The computer you use for configuration should be on the same subnet as the Switch.

The Login screen appears. Enter admin in the Username field and enter the password in the Password field. If this is the first time you are using the utility, leave the Password blank. Then press OK to log in. The Setup tab’s Summary screen appears.

(After you have completed your first login, for security purposes it is recommended that you set a password at a later time. For detailed information on changing the password, refer to section “Admin > User Authentication.”)

Login Screen

Configuration Using the Web-based Utility

Each time you log in, the web-based utility first displays the Setup tab’s Summary screen. To access another screen, you first select the appropriate category from among the 11 tabs that appear at the top of the screen: Setup, Port Management, VLAN Management, Statistics, Security, QoS, Spanning Tree, Multicast, SNMP, Admin, and Logout. Then, select the desired screen from the list directly below the tab names.

Setup

The Setup tab contains the Summary, Zoom, Network Settings, Time, and Stack Management screens.

Setup > Summary

The Summary screen displays a summary of Switch information. The settings shown cannot be modified from the Summary screen; however, many of them can be modified from the Setup tab’s Network Settings screen.

Setup > Summary

The Summary screen has two sections: Device Information and System Information. These are described below.

Device Information

System Name  Displays the name of the Switch, if one has been entered on the Setup tab’s Network Settings screen.

IP Address  The IP address assigned to the Switch. The Switch’s default IP address is 192.168.1.254. This setting can be configured from the Setup tab’s Network Settings screen.

Subnet Mask  The Subnet Mask assigned to the Switch. The default is 255.255.255.0. This setting can be configured from the Setup tab’s Network Settings screen.

SLM224G4S specifications

The Linksys SLM224G4S is a sophisticated Layer 2 managed switch designed for businesses and institutions that demand high performance, reliability, and advanced networking features. This model stands out due to its blend of robustness and manageability, making it ideal for expanding networks.

One of the primary features of the SLM224G4S is its 24 Gigabit Ethernet ports, allowing for high-speed data transfers essential for bandwidth-intensive applications. Supporting auto-negotiation, these ports can detect the capabilities of connected devices and configure themselves accordingly, ensuring optimal performance without manual intervention. With four additional shared Gigabit SFP (Small Form-factor Pluggable) ports, this switch provides flexibility in network design and enhances scalability.

The SLM224G4S supports VLAN (Virtual Local Area Network) capabilities, which can segment network traffic to improve security and performance. This is particularly useful in environments where different departments or teams require distinct network segments for operational efficiency. By implementing VLANs, organizations can enhance their network management while isolating sensitive information from potential threats.

Quality of Service (QoS) is another critical technology integrated into the SLM224G4S. It prioritizes network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly important for VoIP and video conferencing applications, where latency and jitter can significantly impact user experience.

The switch also features advanced Layer 2 management functionalities, including SNMP (Simple Network Management Protocol), allowing IT administrators to monitor network performance and quickly troubleshoot issues. The embedded web-based management interface makes configuration straightforward, enabling quick adjustments to settings without deep networking knowledge.

Security is a paramount consideration in today’s networking landscape. The SLM224G4S provides robust security features, including port security that limits the number of MAC addresses allowed on a port, reducing the risk of unauthorized access. Moreover, it supports802.1X port-based authentication, ensuring that only authenticated devices can connect to the network.

In summary, the Linksys SLM224G4S managed switch boasts features such as 24 Gigabit Ethernet ports, VLAN support, QoS, SNMP management, and advanced security protocols. These characteristics make it an excellent choice for businesses looking to enhance their network's performance, safety, and reliability, paving the way for seamless connectivity in today’s digital age.
