CURR is the current value, and CUMULATIVE is the total since the last IPL of the node.

Information in this Display:

●ICMP Errors – is the number of ICMP packets generated by this node.

●Pkt Too Short – is the number of datagrams received with a length shorter than that specified in the header, or shorter than the ICMP minimum length.

●Old Too Short – is the number of old version ICMP datagrams that were too short.

●Bad Checksums – is the number of ICMP messages received with a bad checksum.

●Old ICMP – is the number of old version ICMP datagrams received.

●Bad Pkt Length – is the number of ICMP datagrams received with a length too short for the given ICMP message type.

●Bad ICMP Code – is the number of ICMP datagrams received with a bad code (which identifies parameters for the control message).

●Responses Cnt – is the total number of responses from this node to echoes and requests for timestamps, information, and address masks (all described later).

●Out Echo Reply – is the number of outgoing responses to ICMP echo request dat- agrams, which are sent by other entities in the IP network as a means of con- firming that communication is possible.

●In Echo Reply – is the number of incoming ICMP echo responses, sent by other entities in the IP network in response to echo requests (see "Out Echo") from this node.

●Out/In Dest Unrech – is the number of outgoing datagrams that could not be delivered because the destination device/network was not reachable, a nec- essary protocol was not running, or fragmentation was necessary but disallowed (due to the "don't frag" flag being set). The message text saysOutgoing if this node is a point in the path of the datagram, and Incoming if the datagram origi- nated at this node.

●Out/In Pkt Lost – is the number of datagrams transmitted by this node that sub- sequently were lost. The message text says Outgoingif this node is a point in the path of the datagram, and Incoming if the datagram originated at this node.

●Out/In Redirect – is the number of datagrams transmitted by this node that sub- sequently were redirected within the same network. The message text says Out- going if this node is a point in the path of the datagram, and Incoming if the datagram originated at this node.

●Out Echo – is the number of requests to other entities in the IP network to respond, as a means of confirming that communication is possible.

●In Echo – is the number of requests from other entities in the IP network to respond to those entities, as a means of confirming that communication is pos- sible.

●Out/In Time Exceed – is the number of transmitted datagrams that subsequently were discarded by a router due to expiration of the datagram's "time to live," or by a destination host due to inability to reassemble the datagram within the nec- essary time period. The message text says Outgoing if this node is a point in the path of the datagram, and Incoming if the datagram originated at this node.

1800 specifications

Cabletron Systems, a leading player in network management and telecommunications solutions during the late 20th century, introduced several innovative products that played a crucial role in shaping enterprise networking. Among these were the Cabletron FRX6000, FRX4000, and the FRX1800, which delivered advanced features aimed at enhancing network performance, security, and scalability.

The Cabletron FRX6000 was designed as a robust multi-layer switch, ideal for large-scale enterprise environments. It supported extensive routing capabilities, allowing organizations to manage traffic efficiently even under heavy loads. The FRX6000 boasted high throughput rates and low latency, making it suitable for demanding applications. With support for various network protocols, including IP, IPX, and AppleTalk, its adaptability made it a versatile choice for diverse networking needs. Moreover, security features like VLAN support and Access Control Lists (ACLs) provided enhanced protection against potential threats.

Moving to the FRX4000, this model offered a balance between performance and cost-effectiveness. The FRX4000 maintained many of the essential features of its larger counterpart while catering to medium-sized enterprises. It provided Layer 3 routing and could handle multiple simultaneous connections, ensuring seamless communication across departments. The modular design allowed for easy upgrades, enabling businesses to expand their network infrastructure without significant overhauls. This made the FRX4000 an attractive option for organizations looking to optimize their network investments.

Lastly, the FRX1800, designed for small to medium businesses, focused on simplicity and ease of use while still incorporating powerful network management capabilities. Its user-friendly interface made it accessible for organizations lacking extensive IT resources. The FRX1800 provided essential functionalities such as Integrated Layer 2 switching and routing, network monitoring, and basic security features, ensuring that even smaller companies could maintain efficient, reliable networking without overwhelming complexity.

All three models utilized advanced technologies, including a high bandwidth backbone and state-of-the-art switching architecture, to enable fast and reliable data transfer. They also supported Quality of Service (QoS) mechanisms, allowing businesses to prioritize critical applications and ensure consistent performance across the network.

In summary, the Cabletron FRX6000, FRX4000, and FRX1800 were pivotal in enhancing network capabilities, providing organizations with scalable, secure, and high-performance options tailored to their specific needs.
