swL2DevInfoFrontPanelLedStatus
Module: DES1228ME-L2MGMT-MIB
OID (symbolic): DES1228ME-L2MGMT-MIB::swL2DevInfoFrontPanelLedStatus
OID (numeric): 1.3.6.1.4.1.171.11.116.1.2.1.1.5
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This object is a set of system LED indications.
When log in system DES1228/ME which do not support POE, the first two octets is defined as system LED. The first LED is power LED. The second LED is console LED.
When log in system DES1228P/ME which support POE, the first four octets are defined as system LED. The first octet is 0x02 and the second octet is 0x01 when in normal mode. Contrarily, the first octet is 0x01 and the second octet is 0x02 when in poe mode. The third octet indicates the power LED. The fourth octet indicates the console LED.
The other octets are defined as follow:
start on the third or fifth octets separately correspond to system support poe or system which does not support poe indicate the logical port LED (following swL2BasePort ordering). Every two bytes are presented to a port. The first byte is presentd to the Link/Activity LED. The second byte is presented to the Speed LED.
Link/Activity LED :
The most significant bit is used for blink/solid: 8 = The LED blinks.
The second significant bit is used for link status:
1 = link fail.
2 = link pass.
Speed LED :
01 = 10Mbps.
02 = 100Mbps.
03 = 1000Mbps.
The four remaining bits are currently unused and must be 0.
What is swL2DevInfoFrontPanelLedStatus?
Returns the switch's front-panel LEDs as a raw byte string: on the non-PoE DES1228/ME the first two bytes are the power and console LEDs, while on the PoE DES1228P/ME the first four bytes are the system/PoE-mode, power and console LEDs, followed by two bytes per port (Link/Activity, then Speed). Per-port bytes use the high bit for blink versus solid, 1 for link fail and 2 for link pass, and speed codes 01/02/03 for 10/100/1000 Mbps, so an admin can read the physical LED state remotely without visiting the rack.
