  • Page 247: F Ip Network Addressing Scenarios

    IP Network Addressing Scenarios 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 typical customer network management system (NMS) scenarios.

  • Page 248: Scenario 1

    F. IP Network Addressing Scenarios Scenario 1 The first scenario series of standalone 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.

  • Page 249: Scenario 2

    Scenario 2 The second scenario carrier communicating with standalone remotes. This scenario is similar to the previous one, treating the carrier devices as the daisy-chained devices. All devices are still on the same subnet, and the subnet mask is FF.FF.FF.00. A static route still must be set in the NMS host to subnet 135.18.2.0.

  • Page 250: Scenario 3

    F. IP Network Addressing Scenarios Scenario 3 This third scenario shows a local carrier connected to remote carriers that have remote standalones. Each carrier must be on a separate subnet but, as in the previous scenario, the carrier-remote combination can share a common subnet. Once again, the subnet mask is FF.FF.FF.00 for all devices.

  • Page 251: Scenario 4

    Scenario 4 An alternative addressing scheme, for the network is shown in Carrier Connected to Remote Carriers – an subnet mask of FF.FF.00.00 for the COM port in the central-site carrier (only), with all of the remaining subnet masks set to FF.FF.FF.00. The advantage to this scheme is that only one route must be added to the NMS host (135.18.0.0).
