Configuration Using the Web-based Utility

Query

Interface  Use this to query the table for a specific port or LAG. Select Port or LAG and select the interface from the drop-down menu.

MAC Address  Use this to query the table for a specific MAC address. Enter the MAC address in the field.

VLAN ID  Use this to query the table for a specific VLAN ID. Enter the VLAN ID in the field.

Address Table Sort Key  Specifies how the search results will be sorted—by Address, VLAN, or Interface.

Specify the search criteria (Interface, MAC Address, or VLAN) and the sort method for the search results, then click Query to display the dynamic addresses matching the search criteria.

Admin > Port Mirroring

Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. Port mirroring can be used as diagnostic tool and/or a debugging feature. Port mirroring also enables switch performance monitoring.

Network administrators configure port mirroring by selecting a target port to which the packets are copied, and the source port(s) from which the packets are copied. Port mirroring supports a maximum of one target port and four source ports.

Admin > Port Mirroring

Set the following attributes for port mirroring using the Port Mirroring screen.

Target Port  The port that will mirror the traffic on the source port.

Source Port  The port whose traffic will be monitored.

Type  Allows you to select which traffic to mirror to the target port; receive, transmit, or both.

RxOnly  (Default) Mirror only received traffic.

TxOnly  Mirror only transmitted traffic.

Both  Mirror both received and transmitted traffic.

Specify the source port, the traffic type to be mirrored, and the target port, then click Add to List. The mirror session is displayed in the text box.

Admin > Cable Test

The Cable Test screen uses Time Domain Reflectometry (TDR) technology to test the quality and characteristics of a copper cable attached to a port. The cable being tested can be up to 120 m in length. Before you can perfom the test, the port to which the cable is connected must be in the down state.

Admin > Cable Test

The Cable Test screen contains the following fields. Unit No.  The unit to which the test cable is connected. Port  The port to which the test cable is connected. Test Result  The results of the test. Possible values are:

OK  The cable passed the test.

No Cable  No cable is connected to the port.

Open Cable  The cable is connected on only one side.

Short Cable  A short has occurred in the cable.

Undefined  The test could not be properly performed.

Last Update  Displays when the last cable test was performed on the port.

Test  Click this to start testing the cable attached to the port. The test results will appear in the Test Result column.

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.
