Enable DDH on the fiber optic switch

ODN and passive infrastructure knowledge brief Published 25 Jul 2025

Prepared for preliminary research by the GESTIONVAL ODN knowledge desk. Confirm network topology, split ratio, box or cabinet capacity, joint closure rating and loss budget against current standards and product documentation.

To enable DDH on a fiber optic switch, access the switch management interface (CLI or GUI), configure the relevant port or module settings, and activate the feature through the switch's advanced options.Accessing the Switch
  1. Connect to the switch via SSH, Telnet, or the vendor's management GUI. For Arista switches, use the connect switch switch-name command to access the CLI . For Dell EMC MXG610s, log in to the OpenManage Enterprise – Modular (OME-M) GUI or WebTools interface .
  2. Ensure proper licensing if using Fibre Channel features, as on Cisco Nexus switches, where a Storage Protocol Services license is required for operational Fibre Channel interfaces .
Configuring Ports
  1. Identify the target port or module where DDH will be enabled. Check the port status LEDs to confirm the module is online and operational .
  2. Enable advanced features on the port. On Arista switches, this may involve entering the debug admin mode or using submodes like config-switch-lag-if for enhanced traffic handling .
  3. Force link-up if necessary to keep the optical interface active even if only the transmit fiber is connected, which can be important for monitoring or diagnostic features .
Activating DDH
  1. Enter the configuration mode for the specific interface or module. For CLI-based switches, this typically involves commands like interface followed by the feature-specific command (e.g., enable ddh or equivalent).
  2. Save the configuration to ensure the feature persists after a reboot. In GUI interfaces, this is usually done by clicking Save after enabling the option .
  3. Verify the feature by checking the operational status of the port or module. Look for LED indicators or CLI status commands that confirm DDH is active and functioning correctly .
Additional Considerations
  • Check compatibility: Not all switch models or modules support DDH. Refer to the vendor's hardware compatibility list.
  • Firmware updates: Ensure the switch firmware is up to date to support advanced features.
  • Safety precautions: When handling optical transceivers, avoid direct eye exposure to laser light . By following these steps, DDH can be enabled on a fiber optic switch, allowing enhanced traffic handling, monitoring, or diagnostic capabilities depending on the vendor and switch model .
