swLedInfoFrontPanelLedStatus
Module: DGS3120-24SC-LED-MIB
OID (symbolic): DGS3120-24SC-LED-MIB::swLedInfoFrontPanelLedStatus
OID (numeric): 1.3.6.1.4.1.171.11.117.1.3.4.1.1.1.2
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object is a set of system LED indicators. The first 32 octets are defined as next, and following octets are for logical port LED.
Octet 1 is box ID led bit 7-6: reserved bit 5-4: 00B = no error 01B = system self-test error 10B = safeguard engine entering the exhausted mode bit 3-0: The actual box ID. 0x1 = box ID 1 0x2 = box ID 2 ...
Octet 2 is power led: 0x01 = power work normally 0x02 = power fail
Octet 3 is RPS led: 0x01 = RPS is not connected 0x02 = RPS is connected to switch but not ready to power the switch 0x03 = RPS is ready to power the switch 0x04 = RPS is powering the switch
Octet 4 is console led: 0x01 = system start up 0x02 = a user is login through console 0x03 = no user is login through console
Octet 5 is master led: 0x00 = standalone 0x01 = master 0x02 = back master 0x03 = slave
Octet 6 is fan led: 0x01 = all fans are OK 0x02 = one or more fans fail
Octet 7 is SD card led: 0x01 = SD card is unplugged 0x02 = SD card is plugged 0x03 = reading/writing 0x04 = read/write fail
Octet 8 is SIO port led: bit 7-2: reserved bit 1: SIO1 link state 0B = linkdown 1B = linkup bit 0: SIO2 link state 0B = linkdown 1B = linkup
Octet 9 is POE led: 0x01 = can not support POE 0x02 = link/act/speed mode 0x03 = POE mode
Octet 10 is port led control state: 0x00 = Port LED control state enabled 0x01 = Port LED control state disabled
Octet 11-32 are reserved.
The continued octets are the logic port led. Each octet presents one port.
There are two modes: link/act/speed mode and POE mode. The link/act/speed mode presents the speed duplex of port. The POE mode presents if the port deliver power to PD. The POE mode is supported by POE Switch only.
The mode is determined by Octet 9. If the switch can not support POE, the mode is link/act/speed only.
In each octet: link/act/speed mode: bit 7: 0B = port is not activity 1B = port is activity bit 6: 0B = not combo port 1B = combo port
bit 5: the bit is available only when the port is combo port and linkup 0B = fiber linkup 1B = copper linkup
bit 4: reserved bit 3: 0B = half duplex 1B = full duplex
bit 2-0: 0x0 = link down 0x1 = 10Mbps 0x2 = 100Mbps 0x3 = 1000Mbps 0x4 = 10Gbps
POE mode: 0x01 = no deliver power to PD 0x02 = deliver power to PD.
What is swLedInfoFrontPanelLedStatus?
This octet-string value packs the switch's entire front-panel LED status into a byte-encoded structure: the first several octets each represent one system-level indicator (box or unit ID, power, redundant power supply, console activity, stack role, fan health, SD card state, SIO port links, and PoE support), and the octets after that represent the link, activity, duplex, and speed status, or PoE delivery state, for every port on the switch, one octet per port. Administrators' management software decodes this single OID rather than polling many separate LED objects individually, useful for building a software replica of the switch's physical status-light panel remotely. For example, if the power-status octet reads a fail value, the software would recognize a power fault on that specific device even without anyone standing in front of the actual LEDs.
