RMON History

Source Interface  Indicates the interface from which the history samples were taken. To specify the interface, select Unit No. (default) and specify the unit number and port from the drop-down menus, or select LAG and select the LAG number from the drop-down menu.

Sampling Interval  Indicates (in seconds) how often samples are taken from the ports. The range is 1 to 3600. The default is 1800 seconds (30 minutes).

Current Number of Samples to Keep  Indicates the number of samples to save.

Owner  Displays the RMON station or user that requested the RMON information. Maximum length is 20 characters.

Click Add to List to add the configured RMON sampling to the Log Table at the bottom of the screen.

Log Table

Source Interface  Displays the interface from which the history samples were taken.

Sampling Interval  Indicates the time in seconds that samplings are taken from the port.

Sampling Requested  Displays the number of samples to be saved. The range is 1-65535. The default value is 50.

Current Number of Samples  Displays the current

number of samples taken.

Owner  Displays the RMON station or user that requested the information.

Click View History Table to open the RMON History Table screen.

To delete an entry from the Log Table, select the entry, then click Delete.

RMON History Table

Statistics > RMON History > RMON HIstory Table

The RMON History Table screen contains interface specific statistical network samplings. Each table entry represents all counter values compiled during a single sample.

History Entry No.  Displays the history table entry number.

Owner  Displays the RMON station or user that requested the RMON information. The maximum length is 20 characters.

Sample No.  Indicates the sample number from which the statistics were taken.

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.

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.
