Assigning SNMP Community Names and Access Levels The DSU can be managed by an SNMP manager supporting the SNMP protocol.
IP Addressing 5 Selecting an IP Addressing Scheme You can select from many IP addressing schemes to provide SNMP NMS connectivity. Review the following information in preparation for selecting an IP addressing scheme. Assign IP addresses to: — The Management port — The IMC Refer to the IP Addressing Scheme Examples section. When the Routing Information Protocol (RIP) option is set to Proprietary, IP routing information is automatically passed between interconnected DSUs from the network side.
IP Addressing IP Addressing Scheme Examples Management of IP addressing is based upon individual IP addresses assigned to each interface. The IP interfaces for the unit are the: Management port: Set the Port Use option to Net Link; see Management Port Options, Table A-5. IMC: Set the In-Band Management Channel Rate (bps) to 1600, 4000, or 8000 bps; see Network Interface Options, Table A-2.
IP Addressing Using Routers to Route DSU Management Data In this example, the DSUs: Receive their management data through the Management port connection to the AUX port of the router. Do not route the data among themselves. Routers route management data for the connected DSUs using the management data path between the routers. The illustration shows each DSU with its own subnet. This subnet is independent of the subnet on the LAN, which is supported by the local router.
IP Addressing Assigning IP Addresses and Subnet Masks Once you select an IP scheme, assign an address(es) to the DSU. If using . . . Then . . . The Management port as a management interface Assign the Management port IP address and subnet mask. Refer to Communication Protocol Options, Table A-9.
