IP Network Addressing Scenario F

Overview

This 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 a typical customer network management system (NMS)

scenario. 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.

IP Network Addressing

The IP network addressing scenario (Figure F-1) consists of a series of 31xx

Series devices daisy chained together, with remotes connected via the FDL. In

this scenario, all 31xx Series devices are on the same subnet (135.18.1.0). The

subnet mask for each device is FF.FF.FF.00. A static route is set in the NMS host

to subnet 135.18.1.0.

The following notes apply to this scenario:

Connections to remote devices may be via EDL 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 end-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

connections.

Although routing table entries are maintained automatically by 31xx Series

devices, without the need for user configuration, only a maximum of 100

routes 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

or remote devices.
