1What: /sys/class/leds/<led>/device_name 2Date: Dec 2017 3KernelVersion: 4.16 4Contact: linux-leds@vger.kernel.org 5Description: 6 Specifies the network device name to monitor. 7 8What: /sys/class/leds/<led>/interval 9Date: Dec 2017 10KernelVersion: 4.16 11Contact: linux-leds@vger.kernel.org 12Description: 13 Specifies the duration of the LED blink in milliseconds. 14 Defaults to 50 ms. 15 16 When offloaded is true, the interval value MUST be set to the 17 default value and cannot be changed. 18 Trying to set any value in this specific mode will return 19 an EINVAL error. 20 21What: /sys/class/leds/<led>/link 22Date: Dec 2017 23KernelVersion: 4.16 24Contact: linux-leds@vger.kernel.org 25Description: 26 Signal the link state of the named network device. 27 28 If set to 0 (default), the LED's normal state is off. 29 30 If set to 1, the LED's normal state reflects the link state 31 of the named network device. 32 Setting this value also immediately changes the LED state. 33 34 35What: /sys/class/leds/<led>/tx 36Date: Dec 2017 37KernelVersion: 4.16 38Contact: linux-leds@vger.kernel.org 39Description: 40 Signal transmission of data on the named network device. 41 42 If set to 0 (default), the LED will not blink on transmission. 43 44 If set to 1, the LED will blink for the milliseconds specified 45 in interval to signal transmission. 46 47 When offloaded is true, the blink interval is controlled by 48 hardware and won't reflect the value set in interval. 49 50What: /sys/class/leds/<led>/rx 51Date: Dec 2017 52KernelVersion: 4.16 53Contact: linux-leds@vger.kernel.org 54Description: 55 Signal reception of data on the named network device. 56 57 If set to 0 (default), the LED will not blink on reception. 58 59 If set to 1, the LED will blink for the milliseconds specified 60 in interval to signal reception. 61 62 When offloaded is true, the blink interval is controlled by 63 hardware and won't reflect the value set in interval. 64

set to 0 (default), the LED's normal state is off. 86 87 If set to 1, the LED's normal state reflects the link state 88 speed of 10MBps of the named network device. 89 Setting this value also immediately changes the LED state. 90 91What: /sys/class/leds/<led>/link_100 92Date: Jun 2023 93KernelVersion: 6.5 94Contact: linux-leds@vger.kernel.org 95Description: 96 Signal the link speed state of 100Mbps of the named network device. 97 98 If set to 0 (default), the LED's normal state is off. 99 100 If set to 1, the LED's normal state reflects the link state 101 speed of 100Mbps of the named network device. 102 Setting this value also immediately changes the LED state. 103 104What: /sys/class/leds/<led>/link_1000 105Date: Jun 2023 106KernelVersion: 6.5 107Contact:
