Admin > Logging

Admin > Logging

The System Logs allow you to view device events in real time, and recording the events for later usage. System Logs record and manage events and report errors or informational messages.

Event messages have a unique format, as per the SYSLOG protocols recommended message format for all error reporting. For example, Syslog and local device reporting messages are assigned a severity code, and include a message mnemonic, which identifies the source application generating the message. It allows messages to be filtered based on their urgency or relevancy. Each message severity determines the set of event logging devices that are sent per each event logging.

Enable Logging  If this option is selected, device global logs for Cache, File, and Server Logs are enabled. The default is enabled.

•Emergency  The system is not functioning.

•Alert  The system needs immediate attention.

•Critical  The system is in a critical state.

•Error  A system error has occurred.

•Warning  A system warning has occurred.

•Notice  The system is functioning properly, but system notice has occurred.

•Informational  Provides device information.

•Debug  Provides detailed information about the log. If a Debug error occurs, contact Customer Tech Support.

If you enable Logging, use the checkboxes to set the level of event messages to be logged to RAM (Memory Logs) and flash memory (Flash Logs), then click Save Settings.

Admin > Server Logs

The Server Logs screen contains information for viewing and configuring the Remote Log Servers. New log servers can be defined, and the log severity sent to each server.

Admin > Server Logs

Server  Specifies the server to which logs can be sent.

UDP Port (1-65535) Defines the UDP port to which the server logs are sent. The possible range is 1 to 65535. The default value is 514.

Facility  Defines a user-defined application from which system logs are sent to the remote server. Only one facility can be assigned to a single server. If a second facility level is assigned, the first facility is overridden. All applications defined for a device utilize the same facility on a server. The default value is Local 7. The range of values is Local 0 to Local 7.

Description  Provides a user-defined server description.

Minimum Severity  Indicates the minimum severity from which logs are sent to the server. For example, if Notice is selected, all logs from a Notice severity and higher are sent to the remote server.

Click Add to List to add the Server Log configuration to the Server Log Table at the bottom of the screen.

Admin > Memory Logs

The Memory Log screen displays all system logs in the chronological order that they are saved in RAM (Cache).

Log Index  Displays the log number.

Log Time  Displays the date and time of log generation.

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.
