Configuration Using the Web-based Utility

The Network Settings screen allows you to edit the following information.

Identification

System Name  Specifies the name of the Switch. Enter the name into the text field provided. By default, the system name is LS-SLM224G4or LS-SLM248G4.

System Location  This is used to enter a description of where the Switch is physically located, such as 3rd Floor.

System Contact  Enter the name of the administrator responsible for the system.

System Object ID  This is used for SNMP purposes and is set to 1.3.6.1.4.1.3955.6.5.224(248).2.

Base MAC Address  Displays the Switch’s physical address.

IP Configuration

Management VLAN  This drop-down menu allows you to select the Management VLAN. The default value is 1.

WARNING: If the system IP address (IP Address field) is set to 192.168.1.254, then keep the default values for the Management VLAN field (default value: 1), and the Default Gateway field (default value: 0.0.0.0). These fields must remain set to the default values. Otherwise, you may not be able to access the system.

IP Address Mode  Specifies whether the Switch’s IP address is Static or dynamically assigned using DHCP (Dynamic Host Configuration Protocol). Selecting Static allows you to enter a static IP address, subnet mask and default gateway using the text field provided. The default setting is Static.

IP Address  If you are using a static IP address, enter the IP address here. The Switch’s default IP address is 192.168.1.254.

Subnet Mask  If you are using a static IP address, enter the subnet mask for the currently configured IP address. The default subnet mask is 255.255.255.0.

Default Gateway  If you are using a static IP address, enter the IP address of the default gateway. The default value is 0.0.0.0.

DNS Server  If you are using a static IP address, enter the IP address of the DNS server. A second DNS address can be specified in the additional text field provided.

Click Save Settings to save your changes. Click Cancel Changes to cancel your changes.

Setup > Time

The Time screen allows you to configure the time settings for the Switch.

Setup > Time

Local Time

Here you set the system date and time for the Switch. All settings noted as“two-digit”must contain a leading zero if the value is less than 10 (for example, 01 instead of 1).

Hours  Enter the two-digit hour here. Minutes  Enter the two-digit minutes here. Seconds  Enter the two-digit seconds here. Month  Enter the two-digit month here. Day  Enter the two-digit day here.

Year  Enter the last two digits of the year here (for example, 07 instead of 2007).

Time Zone  Select your time zone from the drop-down menu. Time zones are identified by the difference between Greenwich Mean Time (GMT) and local time.

Daylight Saving

This is where you configure Daylight Saving Time.

Daylight Saving  To enable daylight saving time, check the box, then select either USA or European to use US or European daylight saving time, respectively. To use a different type of daylight saving time, select Custom, then customize the following settings:

Time Set Offset  Enter the time difference in minutes for daylight saving time. The default is 60 minutes.

From  Enter the starting date for daylight saving time using the format DD/MM/YY.

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.
