The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The default is port leds enable; that is, the LEDs of all the ports reflect their current statuses .
Global Configuration mode
To turn off all ports LEDs on device, use the no port leds enable Global Configuration mode command. Use port leds enable to restore LEDs to current status
The following example shows how to disable and enable port leds statuses:
switchxxxxxx(config)# no port leds enable
switchxxxxxx(config)# show port leds configuration
Port LEDs: Disabled
switchxxxxxx(config)# port leds enable
