RMON

RMON (Remote Networking Monitoring) is an SNMP specification that enables an SNMP agent in the switch to monitor traffic statistics over a given period and send traps to an SNMP manager. The local SNMP agent compares actual, real-time counters against predefined thresholds and generates alarms, without the need for polling by a central SNMP management platform. This is an effective mechanism for proactive management, provided that you have right thresholds set relative to your network base line.

RMON decreases the traffic between the manager and the switch because the SNMP manager does not have to frequently poll the switch for information, and enables the manager to get timely status reports because the switch reports events as they occur. Use the RMON Statistics page to display details about switch use, such as packet processing statistics and errors that have occurred on the switch.

The RMON Statistics page displays detailed information regarding packet sizes and information regarding physical layer errors. The information shown is according to the RMON standard.

To view statistics:

STEP 1 Click Status and Statistics > RMON > Statistics in the navigation window.

STEP 2 Select the port or LAG for which you want to display statistics.

STEP 3 Select a refresh rate for the page.

The following information displays for the selected interface:

Bytes Received—Octets received on the interface since the switch was last refreshed. This number includes bad packets and FCS octets, but excludes framing bits.

Drop Events—Number of times that packets have been dropped on the interface since the switch was last refreshed.

Packets Received—Packets received on the interface, including bad packets, multicast and broadcast packets, since the switch was last refreshed.

Broadcast Packets Received—Good broadcast packets received on the interface since the switch was last refreshed. This number does not include multicast packets.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
