Configure IP Procedure for DCN Core Switch

To configure the IP address on a DCN core switch, assign the NE IP to the loopback or physical interface, set the subnet mask, and enable DCN globally and on the interface.Step 1: Access the SwitchConnect to the switch using out-of-band management via the console port with a serial cable.Use a terminal emulator (e.g., HyperTerminal, PuTTY) with settings: 9600 baud rate, 8 data bits, no parity, 1 stop bit, no flow control .Step 2: Enter System ViewLog in to the switch CLI.Enter system view by typing:CodeCopysystem-view This allows you to configure global switch parameters .Step 3: Enable DCNEnable DCN globally:CodeCopydcn enable Enter DCN view to configure DCN-specific settings:CodeCopydcn By default, DCN is disabled, so this step is required for all subsequent DCN configurations .Step 4: Configure NE ID and NE IPBy default, the NE ID is generated from the lower 24 bits of the MAC address. You can manually configure it if needed:CodeCopydcn ne-id Assign the NE IP to the loopback interface or physical interface:CodeCopyinterface loopback ip address For physical interfaces, navigate to the interface view:CodeCopyinterface dcnip address Ensure the subnet mask is valid (network portion with contiguous 1s, host portion with contiguous 0s) and within supported ranges (1-99, 101-126, 128-223 for first octet), .Step 5: Configure DCN VLAN (if required)Assign the interface to a DCN VLAN to ensure proper communication with the GNE and NMS:CodeCopydcn vlan This step ensures the NE IP is advertised correctly in the DCN domain via OSPF and LLDP .Step 6: Verify ConnectivityCheck that the NE IP is reachable from the GNE and NMS.Use ping or Telnet/SSH to confirm connectivity.Ensure the NE IP is advertised in the DCN core routing table and synchronized with other NEs .Step 7: Save ConfigurationCommit and save the configuration to prevent loss after reboot:CodeCopysave Optional StepsEnable automatic NE reporting on the GNE to notify the NMS of new NEs.Configure LLDP management addresses for network discovery and management . Following these steps ensures that the DCN core switch is properly configured with a static or planned NE IP, integrated into the DCN network, and ready for management by the NMS.
