Statistics Window Fields

The following informational and statistics Þelds appear in the interface Statistics window.

Three informational Þelds appear in the upper portion of the window:

Description

Describes the interface description for the currently selected port.

Address

Displays the MAC (physical) address of the selected port.

Type

Displays the interface type of the selected port.

The following transmit and receive statistics Þelds are displayed in the lower portion of the window. The Þrst four statistics are also graphically displayed in a pie chart. The statistics are read directly from the device, and are updated with each poll from SPECTRUM Element Manager to the device.

Unicast

Displays the number of packets transmitted to, or received from, this interface that had a single, unique source or destination address. These statistics are displayed in the pie chart (color-coded green).

Non-Unicast

Displays the number of packets transmitted to, or received from, this interface that had a source or destination address that is recognized by more than one device on the network segment. The non-unicast Þeld includes a count of broadcast packetsÑthose that are recognized by all devices on a segment. These statistics are displayed in the pie chart (color-coded dark blue).

Discarded

Displays the number of packets which were discarded even though no errors were detected to prevent transmission. One possible reason for discarding such a packet could be to free up buffer space.

Discarding good packets indicates a very busy network. If a device routinely discards packets, it usually means that network trafÞc is overwhelming the device, perhaps because the device is performing poorly.

These statistics are displayed in the pie chart (color-coded hot pink).

Error

Displays the number of packets received or transmitted that contained errors. These statistics are displayed in the pie chart (color-coded red).

Cabletron Systems CSX400, CSX200 manual Statistics Window Fields, Description

CSX200, CSX400 specifications

Cabletron Systems was a leading developer of networking solutions, and its CSX400 and CSX200 series of high-performance switches represent some of the key innovations in the field of enterprise networking during their time. Both models were geared towards enhancing network reliability, efficiency, and speed, particularly in environments where heavy data traffic and complex networking demands were prevalent.

The CSX400, designed for larger enterprises, boasts a robust architecture capable of handling significant throughput. One of its standout features is its stackable design, allowing multiple switches to be interconnected and managed seamlessly as a single unit. This scalability provides organizations with the flexibility to expand their networks without significant infrastructure overhauls. The CSX400 supports various Ethernet standards, including 10/100 Ethernet and Gigabit Ethernet, positioning it to effectively manage both legacy and modern networking requirements.

In addition to its scalability, the CSX400 is distinguished by its advanced Layer 2 and Layer 3 routing capabilities. This dual-layer functionality enables efficient data handling and is instrumental in managing traffic between different network segments. Moreover, the switch incorporates features like VLAN (Virtual Local Area Network) support and Quality of Service (QoS) prioritization, allowing for enhanced performance of critical applications and streamlined bandwidth allocation.

On the other hand, the CSX200 series is tailored for smaller enterprises or branch offices needing a reliable yet efficient networking solution. Despite its compact design, the CSX200 is equipped with essential features that promote effective network management and security. It offers a simplified management interface, making it user-friendly for network administrators. The switch also provides essential access control measures, employing technologies like IEEE 802.1X for network access security.

Both the CSX400 and CSX200 prioritize performance through the incorporation of advanced switching technologies. They support features such as Spanning Tree Protocol (STP), enabling loop-free topologies and enhanced network resilience. These attributes are particularly crucial in dynamic networking environments where downtime can have significant repercussions on business operations.

Overall, Cabletron Systems' CSX400 and CSX200 series represent a blend of scalability, advanced routing capabilities, and user-friendly management, making them vital assets for organizations looking to optimize their network infrastructure during a period of rapid technological evolution. With their rich feature sets and unwavering performance, these switches helped pave the way for modern networking solutions that cater to diverse enterprise needs.
