F-1 3162-A2-GB20-40 August 2000 IP Network Addressing Scenario F Overview This appendix describes a means of configuring 31xx Series devices in anInternet Protocol (IP) network to provide SNMP or Telnet connectivity. Since thereare many possible network addressing schemes, this appendix describes an...

IP Network Addressing Scenario F-2 3162-A2-GB20-40 August 2000 Standalone at the Central Site The first scenario (Figure F-1) shows a 3162 DSU/CSU at the central site, withremotes connected via the FDL. In this scenario, all 31xx Series devices are onthe same subnet (135.18.1.0). The subnet mask for...

IP Network Addressing Scenario F-3 3162-A2-GB20-40 August 2000 Local Carrier with Remote Standalone The second scenario (Figure F-2) is a carrier communicating with standaloneremotes. All devices are still on the same subnet, and the subnet mask is255.255.255.00. A static route still must be set in ...

IP Network Addressing Scenario F-4 3162-A2-GB20-40 August 2000 Local and Remote Carriers — Different Subnets This third scenario (Figure F-3) shows a local carrier connected to remotecarriers that have remote standalones. Each carrier must be on a separatesubnet but, as in the previous scenario, the...

IP Network Addressing Scenario F-5 3162-A2-GB20-40 August 2000 Local and Remote Carriers — Same Subnet An alternative addressing scheme, for the network is shown in Figure F-4. Thisexample uses a subnet mask of 255.255.00.00 for the COM port in thecentral-site carrier (only), with all of the remaini...

IP Network Addressing Scenario F-6 3162-A2-GB20-40 August 2000 Multiple NMSs Figure F-5 illustrates multiple COM ports on the same carrier connected todifferent NMSs. This might be used in service-provider applications, where someof the carrier’s circuit cards (and their remotes) are managed by one ...
