VLAN Management > VLAN to Port > Join VLAN to Port

Select VLAN  This contains two fields. The field on the left lists the IDs of all available VLANs to which the port can belong; the field on the right lists the IDs of the VLANs to which the port already belongs.

Add  To add the port to an available VLAN, select the VLAN from the list on the left, then select the desired Tagging option and click Add. The VLAN ID now ending with “T” or “U” will appear in the list on the right.

Remove  To remove the port from a VLAN, select the VLAN from the list on the right and click Remove. The VLAN ID will appear in the list on the left without the “T” or “U”.

Tagging  When you are adding a port to a VLAN, specify whether the port is Tagged (default) or Untagged.

Click Save to save your changes and leave the screen open, Save & Close to save your changes and close the screen, or click Close to close the screen without saving your changes.

Statistics

The Statistics tab contains the Interface Statistics screen, which lets you display statistics for a specified interface.

Statistics > RMON Statistics

Statistics > RMON Statistics

This screen allows you to display RMON statistics for the Ethernet port or LAG that you specify. You can also specify the rate at which the display will be refreshed.

Interface  To display statistics for an Ethernet port, select Unit No., then select the desired unit number and port from the drop-down menus. To display statistics for a LAG, select LAG and then select the desired LAG from the drop- down menu.

Refresh Rate  Select the rate at which to refresh the statistics display. The values are 15 sec, 30 sec, 60 sec, and No Refresh (default).

Drop Events  Displays the number of dropped events that have occurred on the interface since the device was last refreshed.

Received Bytes (Octets)  Displays the number of octets received on the interface since the device was last refreshed. This number includes bad packets and FCS octets, but excludes framing bits.

Received Packets  Displays the number of packets received on the interface, including bad packets, Multicast and broadcast packets, since the device was last refreshed.

Broadcast Packets Received  Displays the number of good broadcast packets received on the interface since the device was last refreshed. This number does not include Multicast packets.

Multicast Packets Received  Displays the number of good Multicast packets received on the interface since the device was last refreshed.

CRC & Align Errors  Displays the number of CRC and Align errors that have occurred on the interface since the device was last refreshed.

Undersize Packets  Displays the number of undersized packets (less than 64 octets) received on the interface since the device was last refreshed.

Oversize Packets  Displays the number of oversized packets (over 1518 octets) received on the interface since the device was last refreshed.

Fragments  Displays the number of fragments (packets with less than 64 octets, excluding framing bits, but including FCS octets) received on the interface since the device was last refreshed.

Jabbers  Displays the total number of received packets that were longer than 1518 octets. This number excludes frame bits, but includes FCS octets that had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral octet (Alignment Error) number. The field range to detect jabbers is between 20 ms and 150 ms.

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.
