IP Status Displays

IP Routing Table

To display a list of active IP routes, press [A] at the IP Status Displays Menu (or [C], [F], [G], [A] from the Main Menu).

Information in this Display:

●Destination – Destination IP address.

●Gateway – IP address of router that provides access to the destination device. (This corresponds to the Router parameter in static IP Routes. (See page 14-15.)

●Ref – (Reference) Internal count of the number of places the route is currently being used in the SmartSwitch 1800 software. The route cannot be removed if this count is greater than zero.

●Use – Number of times the route was used to send a packet.

●Flags: C = Route is on a LAN interface.

G = Route is via a remote gateway (hop count is greater than zero).

H = Route is a Host route.

S= Route is a static route . U = Route is operational.

●Intf – (Interface) Identifier used in the IP Route Display. Each entry is the interface number preceded by the interface type, which is one of these:

fr

Frame relay

x

tr

Token Ring

lo

X.25

en Ethernet

Loopback

 

●Netmask – Network mask, used during routing to determine the portion of the address associated with the network.

Point -to-point frame relay IP connections will display a Netmask of 255.255.255.255, which is the default Destination Mask value (see page 14-15)for Host IP routes. The Netmask configured on the IP interface (see page 14-9) is used by RIP for route summarization.

Each entry is two lines on the screen, with the Netmask on the second line, under the associated Destination.

ARP Table

To display a list of active ARP (Address Resolution Protocol) table entries, press [B] at the IP Status Displays Menu (or [C], [F], [G], [B] from the Main Menu).

Information in this Display:

●IP Address – Address of corresponding IP Interface.

●MAC Address – MAC address to which each IP address maps.

●AgeOut Timer – Time (in seconds) until the address will be removed from the table if no traffic is received from that address. The address is added to the table after the SmartSwitch sends an ARP request for an IP address and receives a MAC address in response. The timer is reset if an IP frame is received from the either the IP or MAC address.

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.
