Configuring a Gateway Half

Configure a Gatehalf Network Interface

Step 7. Tab down to the next field. In the Transmission speed field, either leave the default or enter the transmission speed in bits per second as a number from 1200 to 64000.

Step 8. If this is a dial link, enter the phone number of this gateway half’s partner.

Step 9. If this is a dial link, in the Security string field, either leave the default, or enter a value that HP nodes must use to gain dial link access to the node you are configuring.

Step 10. Press the [Save Data] key. Proceed to Appendix 10 , “Validating and Cross-Validating with SYSGEN,” and press the [Validate Netxport] key.

Optional Keys

Press the [List NIs] key to list the names and types of already configured network interfaces.

Press the [Delete NI] to remove a configured network interface from the configuration file.

Press the [Read Other NI] key to call up a previously configured Network Interface name.

FieldsPartner’s IP address

This is the internet protocol (IP) address of the node that will be the other half of the gateway half you are configuring. Enter the address in the same format as on the Point-to-Point Configuration screen.

Partner’s IP subnet mask

Allows you to specify the subnet mask of this gateway half’s partner gateway half. The 32-bit mask is grouped in octets expressed as decimal integers and delimited by either a period (.) or a space. The mask identifies which bits of an IP address will be used to define a subnetwork. To determine these bits, you first need to estimate how many subnetworks and nodes per subnetwork you need. For details on deriving an IP subnet mask, see Chapter 2 , “Networking Concepts.”

Home NI name

The home NI name will be used by the software to determine which network address is the source network address when packets are sent over the gateway half. The home NI name cannot be either a gateway half or loopback NI name, but it can refer to any other type of network interface (LAN, Token Ring, Point-to-Point, FDDI, or X.25 network interface).

E3000 MPE/IX, E3000/IX specifications

The HP E3000 series, particularly the E3000/IX and E3000 MPE/IX, represents a significant milestone in the evolution of business computing, developed by Hewlett-Packard (HP) during the late 1970s and early 1980s. These systems were designed to provide robust, reliable, and efficient operation for mid-sized businesses, leveraging the power of the MPE (Multi-Programming Executive) operating system.

One of the main features of the HP E3000 series is its multitasking capability. MPE/IX allows for multiple applications to run concurrently, maximizing the utilization of system resources. This is particularly beneficial for organizations that require simultaneous access to various business applications, ensuring enhanced productivity and efficiency.

The HP E3000/IX architecture is built on a powerful 16-bit or 32-bit microprocessor, enabling it to handle substantial workloads. The system architecture is known for its modular design, which allows for easy upgrades and customization. This flexibility is essential for businesses that need to adapt to changing demands without overhauling their entire computing infrastructure.

Another notable technology incorporated into the HP E3000 series is its support for a range of storage solutions. The E3000 systems were compatible with various disk drives, providing organizations with options for data storage that matched their performance and capacity requirements. Additionally, they featured advanced data management capabilities, such as built-in backup and recovery systems, ensuring that critical business information remained secure and accessible.

Beyond hardware capabilities, HP E3000/IX and MPE/IX systems provide extensive programming support. They included tools for developing custom applications, with support for languages such as COBOL, BASIC, and FORTRAN. This versatility made it easier for businesses to tailor their software solutions to their specific needs, enhancing operational effectiveness.

Networking capabilities were also a significant innovation of the E3000 series. The systems offered robust support for various networking protocols, allowing for seamless integration with other computing environments. This facilitated communication and collaboration within an organization, as well as with external partners and clients.

In summary, the HP E3000/IX and E3000 MPE/IX systems were pivotal in delivering reliable computing power to mid-sized enterprises. With their multitasking operating system, modular architecture, advanced data management, and programming support, these systems provided an adaptable and comprehensive solution for evolving business needs. The legacy of the E3000 series is evident in how it paved the way for modern enterprise computing, focusing on flexibility, scalability, and efficiency.
