Configuration Using the Web-based Utility

Acceptable Frame Type  This specifies the type of frames that the port will accept. If All (default) is selected, the port will accept all frame types, including tagged or untagged frames. If Tagged is selected, the port accepts only tagged frames. When set to All, each untagged frame received is assigned to the specific VLAN that matches the PVID.

PVID  Use this field to select the VLAN ID that will be assigned to untagged frames received on the port. Valid IDs are 1 (default) to 4093. VLAN 4094 is reserved for internal use. VLAN 4095 is defined per standard and industry practice as the Discard VLAN. Frames tagged for the Discard VLAN are dropped.

Ingress Filtering  Enables or disables Ingress filtering on the port. Ingress filtering discards packets that do not match port ingress rules. The default is Enabled.

LAG  Displays the LAG, if any, to which the port belongs. A port’s LAG settings override the VLAN port settings.

Click Save Changes to save your changes, or click Cancel Changes to cancel.

VLAN Management > Port to VLAN

You use the Port to VLAN screen to add ports to a VLAN and delete ports from a VLAN. When you add a port to a VLAN, you also specify whether the port is tagged or untagged.

The Port to VLAN screen contains a Port Table with VLAN parameters for each port. To add a port to or delete a port from the VLAN, you select the port’s appropriate configuration options from this table.

VLAN Management > Port to VLAN

Select VLAN  Select the ID of the VLAN whose port membership you are configuring.

Unit No.  Select the unit that contains the ports for the VLAN you are configuring.

For each port in the VLAN, select the appropriate configuration option:

Tagged  The interface is a member of the VLAN. All packets transmitted by the port will be tagged and will carry VLAN information.

Untagged  The interface is a member of the VLAN. All packets transmitted by the port will be untagged and will not carry VLAN information.

Excluded  The interface is excluded from the VLAN. This is the default option.

VLAN Management > VLAN to Port

The VLAN to Port screen displays each port’s VLAN membership information. It is also used to add a port to or delete a port from a VLAN.

Unit No.  The unit number that contains the ports whose VLAN information you wish to configure.

Port  The number of the port being configured.

Join VLAN  To configure the port’s VLAN membership, press Join VLAN to bring up the Join VLAN to Port screen.

VLANs  Displays the IDs of the VLANs to which the port belongs. Each VLAN ID ends with “T” if the port is tagged or with “U” if the port is untagged in that VLAN.

LAG  Displays the LAG to which the port belongs, if any. If a port belongs to a LAG, it cannot belong to a VLAN. However, the LAG to which the port belongs can be configured to belong to a VLAN.

VLAN Management > VLAN to Port

Join VLAN to Port

The Join VLAN to Port screen appears when you click Join VLAN in the VLAN to Port screen. You use this screen to configure the port’s VLAN membership.

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.
