  • Page 22: Ip Addressing

    Applications IP Addressing Devices on an IP network are located by their IP addresses, which is a 32 bit number divided into four 8 bit fields. The IP address identifies both the network and the host device (also known as a node) on that network. The address is usually written as the four decimal values for the fields (between 0 and 255) separated by decimal points;...

  • Page 23: Masks

    Applications Masks The portion of the IP address to use as the network address is specified by using a mask; a mask is the contiguous number of bits to be used for the network address all set to 1. When the mask is logically ANDed with an IP address, the result is the network address.
  • Page 24 The P1705 & P1730 allows mask sizes from 8 to 32 bits. The subnet mask size determines how many bits of the host field of the original IP network address will be used for the creation of subnets. In this example, specifying a mask size of 26 will produce a subnet size of 2 bits.

  • Page 25: Ip Default Gateway

    IP Default Gateway An IP default gateway is an IP router that is resident on the local IP network that this router is connected to and is used to route IP frames for destination networks that do not exist in the routing table. When an IP frame is received that is destined for a network that is not listed in the routing table of the router, the router will send the IP frame to the default gateway.

  • Page 26: Ipx Routing

    IPX Routing The P1705 & P1730 are pre-configured to operate as an IPX router. When installed in an IPX network, the router will learn the IPX network numbers from connected networks. It will then route the IPX frames to the appropriate destination IPX network. The IPX routing scenario may consist of one of the two following configurations.

  • Page 27: Novell Servers In One Location Only

    to the IPX frames they receive from the network. Manual entries may be made in the routing tables by adding static IPX routes. Novell Servers in One Location Only Some Novell LAN installations require that a remote LAN that consists of only Novell IPX clients be connected to a central LAN that contains the Novell servers and some more clients.
  • Page 28 The following steps must be performed on the router connected to LAN #2. IPX Routing Disabled Location: Main Disabling IPX routing allows the IPX frame types to be modified.

    Performing a Software Upgrade Execute the Network (TFTP) command from the Load FLASH Set-Up menu. Enter “none” to connect locally or enter the remote site ID number or alias to connect to a remote site. Start the TFTP application to be used for transfers to the router. (The IP address of the router may be found in the Internet Set-Up menu.).
  • Page 88 In the following diagram of a cluster of routers, when upgrading the three routers in the diagram, the upgrade order should be Router C, then Router B, and finally Router A. A TFTP software load to router C would be performed as follows: Using TFTP, get config.txt from each router and save.

    Servicing Information Appendix D Interface Pinouts Pinout Information Each link interface available is described with detailed information on pin designation. Standard interface cables will provide correct connections to modems, datasets, or DSU/CSUs. When connecting two bridge/routers back-to-back without modems, a null-modem cable is required to crossover the pins on the links.
