IP Interface Configuration

IP Interface Type

In this Þeld, use the menu button to select the type of interface you wish to conÞgure. This selection will change the parameters that appear in the IP Interface ConÞguration window. Depending on your selection, certain parameters will be conÞgurable, and others will be grayed out.

There are Þve IP interface types that you can select from:

¥Rfc 877x25 (X.25)

¥Ethernet Csmacd (Ethernet II)

¥Iso 88023 Csmacd

¥Iso 88025 Token Ring

¥Frame Relay

NOTE

The Ethernet and Token Ring IP Interface types will be referred to collectively as LAN interfaces.

Maximum Transmission Unit

This is the maximum size (in bytes) of the data Þeld that can be used to encapsulate an IP datagram for transmission over the interface. Any datagrams larger than the Maximum Transmission Unit will be fragmented, resulting in additional processing on any intermediate routers or gateways, as well as the destination host. If the maximum Transmission Unit value is less than the size of a minimal IP datagram, the value will automatically change to the minimal datagram size. The default value for this parameter is 1500.

Network Mask

This Þeld is used during routing to determine the portion of the IP address associated with the network and subnetwork (if any). The valid entries are

255.0.0.0to 255.255.255.255 (255.255.255.255 is only valid on a point-to-point interface).

The default value for this parameter is conÞgured automatically to reßect the appropriate address class for the speciÞed Source Address (see below). If the Source IP Address is changed, the Network Mask will automatically change to a default value appropriate for the new address. For this reason, conÞgure the Source IP Address Þrst, then the Network Mask.

If the interface is conÞgured as an Unnumbered Interface (see below), the default value of Network Mask will be based on the numbered interface that is assigned.

Route Metric Hops

This is the number of network hops (network gateways in the overall path over the internet) associated with this interface (usually zero). During routing, the interface with the lowest count will be selected. The default value for this parameter is 0.

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.
