Chad Network Distribution Box Configuration Requirements

Proper configuration of network distribution boxes involves setting IP addresses, subnet masks, gateway parameters, and controller-specific flags to ensure connectivity and DHCP functionality.

Key Configuration Steps

1. IP Addressing and Subnet Configuration Each distribution node (DN) or network box must have a unique IP address, subnet mask, and default gateway to communicate within the network. Ensure that the IP addresses are within the correct CIDR range for your network. For NAT or DHCP-enabled networks, the DHCP server must reflect the correct network CIDR to allocate addresses properly; otherwise, devices may fail to receive valid IPs or network parameters . 2. Controller Communication and Prefix Allocation In multi-PoP (Point of Presence) networks, distribution nodes rely on the E2E Controller to receive IPv6 prefix allocations. The parameter flags.enable_pop_prefix_broadcast determines how prefix allocation messages are sent:

• true: Controller sends prefix allocation to all PoPs individually, useful if PoPs are temporarily isolated.
• false: Controller sends to one PoP, assuming a wired or wireless path exists between PoPs. This parameter can be modified in the device UI under Configuration > E2E Controller and saved to apply changes . 3. DHCP and Network CIDR Alignment Ensure that the DHCP server configuration matches the network CIDR. Changing the network CIDR without updating the DHCP server may result in incorrect IP allocation or unreachable devices. Verify that the DHCP range, gateway, and subnet mask are consistent with the network design . 4. Device-Specific Management Options Some network devices, like APC Network Management Cards, require TCP/IP settings to be configured before network access. Tools such as the Device IP Configuration Wizard can help assign IP, subnet, and gateway settings, either via direct connection or network discovery, depending on firmware and DHCP mode . 5. Best Practices
• Document all IP addresses, subnet masks, and gateway settings for each distribution box.
• Use the device UI or management software for bulk configuration when possible to reduce manual errors.
• Verify connectivity after configuration by pinging the controller and other PoPs.
• Ensure firmware and software versions are compatible with the network management tools. By following these steps, network distribution boxes in Chad can be properly configured to ensure reliable communication, correct IP allocation, and seamless integration with controllers and DHCP servers.
