Configuring Controllers

This chapter describes the Optics Controller for the 36-port QSFP56-DD 400 GbE and 48-port QSFP28 100 GbE Line Cards. This chapter also describes the procedures used to configure the controllers.


Note


When two MACsec enabled Cisco 8000 Series Routers with Coherent Line Cards are connected, there is no compatibility between Coherent Line Cards of IOS XR Release.

  • breakout - Configure breakout mode (‘breakout 4x10’ only.)

  • clear - Clear the uncommitted configuration.

  • commit - Commit the configuration changes to running.

  • do - Run an exec command.

  • end - Exit from configure mode.

  • exit - Exit from this submode.

  • ext-description - Set ext-description for this controller.

  • no - Negate a command or set its defaults.

  • pwd - Commands used to reach current submode.

  • root - Exit to the global configuration mode.

  • show - Show contents of configuration.


Following controller configuration options are supported on the router:

Disabling Optical Modules

This feature provides the ability to disable and re-enable an optical module through CLI, which simulates online insertion and removal (OIR) by disabling power to the transceiver port.

Typical troubleshooting procedures for optical modules can include performing OIR by removing and re-installing the module, which requires onsite personnel to physically reseat the optical module. The ability to remotely disable and enable an optical module can significantly reduce operational expenses.

To disable the module, use the transceiver disable command in controller optics configuration mode:

Router(config)# controller optics 0/0/0/0 
Router(config-Optics)# transceiver disable 
Router(config-Optics)# commit
Router(config-Optics)# end
