IP Network Addressing Scenarios

Overview

his appendix describes a means of configuring 31xx Series devices in an Internet Protocol (IP) network to provide SNMP or Telnet connectivity. Since there are many possible network addressing schemes, this appendix describes an addressing scheme for typical customer network management system (NMS) scenarios. This appendix is not intended to be an IP addressing or routing tutorial, and a basic understanding of IP and 31xx Series devices is assumed.

The following notes apply to these scenarios:

Connections to remote devices may be via EDL (for 2-port and 4-port DSU/CSUs) or FDL; however, the FDL is only available on full T1 links (not fractional T1s). Check with the service provider to be sure that the FDL is

Tend-to-end (i.e., not terminated at an intermediate point within the network).

Interconnected 31xx Series devices automatically pass routing information between them; however, a static route to the subnet(s) must be set in the routing table of the NMS host. This route uses the 31xx Series device connected to the LAN (via the LAN Adapter), or the NMS (via a direct PPP or SLIP connection) as a gateway to the subnet(s). In all instances, the addressing scheme presented works for both the LAN and the direct

Tconnections.

Although routing table entries are maintained automatically by 31xx Series devices, without the need for user configuration, only a maximum of 100

Troutes is supported for a given device.

The choice of a host address within a given subnet is completely arbitrary. Choose any legal host address for a given subnet, without regard to the local

Tor remote devices.

Although the default route (to the NMS) is configurable for all devices, only devices that have a direct external connection to an NMS (via the COM or AUX ports) need a default route set. In the following examples, the default port (COM or AUX) is set in the device connected to the LAN Adapter.
