Bad FCSs

The Bad FCSs Þeld displays the number of received packets that were discarded due to having an incorrect FCS (Frame Check Sequence) value.

Total Errors

The Total Errors Þeld displays the total number of errors of all types: Bad

Addresses, Bad Controls, Packets Too Long, and Bad FCSs.

Statistics

Local MRU

The Local MRU Þeld displays the current value of the MRU (Maximum Receive Unit) for the local PPP entity. This value is the MRU that the remote entity uses when sending packets to the local PPP entity. The MRU is the maximum length of data information (included ÒpaddedÓ data octets, but excluding the Protocol Þeld which identiÞes the datagramÕs protocol type) that can be received by this interface. The default MRU size is 1500 octets. The auto-negotiation process may establish another value for MRU if consent is given at both ends of the PPP link (if either the local or remote PPP entity informs the other that larger packets can be sent, or requests that smaller packets be sent).

Remote MRU

The Remote MRU Þeld displays the current value of the MRU (Maximum Receive Unit) established for the remote interface at the other end of the PPP Link. This value is the MRU that the local entity uses when sending packets to the remote PPP entity.

Local to Peer ACC Map

The Local to Peer ACC Map Þeld displays the current value of the Asynchronous Control Character (ACC) Map used for sending packets from the local PPP entity to the remote PPP entity. In effect, this is the ACC Map that is required in order to ensure that all characters can be successfully transmitted through the local modem. The actual ACC Map used on the transmit side of the link will be a combination of the local nodeÕs pppLinkConÞgTransmitACCMap and the remote nodeÕs pppLinkConÞgReceiveACCMap.

Peer to Local ACC Map

The Peer to Local ACC Map Þeld displays the Asynchronous Control Character (ACC) Map used by the remote PPP entity when transmitting packets to the local

PPPentity. In effect, this is the ACC Map that is required in order to ensure that the local modem will successfully receive all characters. The actual ACC Map used on the receive side of the link will be a combination of the local nodeÕs pppLinkConÞgReceiveACCMap and the remote nodeÕs pppLinkConÞgTransmitACCMap.

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.
