DWDM Tunable Optics Support

This feature provides tunable support for the dense wavelength-division multiplexing (DWDM) wavelengths of the DWDM-XFP-C module on the Cisco NCS 5000 Series Routers. You can configure the DWDM ITU wavelengths by using the itu channel command in the interface configuration mode.

The itu channel command ensures that the traffic continues to flow.

      Upgrading Cisco IOS XR Software

      Cisco IOS XR Software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

      Before starting the software upgrade, use the show install health command in the admin mode. This command validates if the statuses of all relevant parameters of the system are ready for the software upgrade without interrupting the system.


      Note

      If you use a TAR package to upgrade from a Cisco IOS XR release prior to 7.x, the output of the show install health command in admin mode displays the following error messages:

      sysadmin-vm:0_RSP0# show install health
      . . .
