This topic describes how to remove the 4x10 breakout configuration from an optics controller of a port so that the router restores the port to its original 40 Gigabit Ethernet operating mode.

Remove the breakout configuration from the optics controller of a port that was previously configured with the 4x10 breakout mode.

Procedure

  1. Enter global configuration mode.

    Example:

    Router# configure
Sat Oct 12 00:01:38.673 UTC

  2. Enter optics controller configuration mode for the target port.

    Example:

    Router(config)# controller optics 0/1/0/28

  3. Remove the 4x10 breakout configuration from the optics controller.

    Example:

    Router(config-Optics)# no breakout 4x10

  4. Commit the configuration and exit the configuration mode.

    Example:

    Router(config-Optics)# commit
Sat Oct 12 00:01:55.864 UTC
RP/0/RP0/CPU0:uut(config-Optics)# end
