1 What: /sys/class/leds/<led>/device_name
4 Contact: linux-leds@vger.kernel.org
6 Specifies the network device name to monitor.
8 What: /sys/class/leds/<led>/interval
11 Contact: linux-leds@vger.kernel.org
13 Specifies the duration of the LED blink in milliseconds.
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
21 What: /sys/class/leds/<led>/link
24 Contact: linux-leds@vger.kernel.org
26 Signal the link state of the named network device.
28 If set to 0 (default), the LED's normal state is off.
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.
35 What: /sys/class/leds/<led>/tx
38 Contact: linux-leds@vger.kernel.org
40 Signal transmission of data on the named network device.
42 If set to 0 (default), the LED will not blink on transmission.
44 If set to 1, the LED will blink for the milliseconds specified
45 in interval to signal transmission.
47 When offloaded is true, the blink interval is controlled by
48 hardware and won't reflect the value set in interval.
50 What: /sys/class/leds/<led>/rx
53 Contact: linux-leds@vger.kernel.org
55 Signal reception of data on the named network device.
57 If set to 0 (default), the LED will not blink on reception.
59 If set to 1, the LED will blink for the milliseconds specified
60 in interval to signal reception.
62 When offloaded is true, the blink interval is controlled by
63 hardware and won't reflect the value set in interval.
65 What: /sys/class/leds/<led>/offloaded
68 Contact: linux-leds@vger.kernel.org
70 Communicate whether the LED trigger modes are offloaded to
71 hardware or whether software fallback is used.
73 If 0, the LED is using software fallback to blink.
75 If 1, the LED blinking in requested mode is offloaded to
78 What: /sys/class/leds/<led>/link_10
81 Contact: linux-leds@vger.kernel.org
83 Signal the link speed state of 10Mbps of the named network device.
85 If set to 0 (default), the LED's normal state is off.
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.
91 What: /sys/class/leds/<led>/link_100
94 Contact: linux-leds@vger.kernel.org
96 Signal the link speed state of 100Mbps of the named network device.
98 If set to 0 (default), the LED's normal state is off.
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.
104 What: /sys/class/leds/<led>/link_1000
107 Contact: linux-leds@vger.kernel.org
109 Signal the link speed state of 1000Mbps of the named network device.
111 If set to 0 (default), the LED's normal state is off.
113 If set to 1, the LED's normal state reflects the link state
114 speed of 1000Mbps of the named network device.
115 Setting this value also immediately changes the LED state.
117 What: /sys/class/leds/<led>/half_duplex
120 Contact: linux-leds@vger.kernel.org
122 Signal the link half duplex state of the named network device.
124 If set to 0 (default), the LED's normal state is off.
126 If set to 1, the LED's normal state reflects the link half
127 duplex state of the named network device.
128 Setting this value also immediately changes the LED state.
130 What: /sys/class/leds/<led>/full_duplex
133 Contact: linux-leds@vger.kernel.org
135 Signal the link full duplex state of the named network device.
137 If set to 0 (default), the LED's normal state is off.
139 If set to 1, the LED's normal state reflects the link full
140 duplex state of the named network device.
141 Setting this value also immediately changes the LED state.
