A bit encoded string representing the status of faceplate indicators, LEDs, buttons & switches for GUI visualization. The first byte will be the number of LED/switches encoded. The following bytes will contain 2 bit sequences in network order for each LED or switch, from the top to the bottom of the faceplate. The final byte may be padded with zeros. The meaning of each pair of bits for LEDs is: 00 - off 01 - color A on only 10 - color B on only (not used for mono-colors) 11 - both A & B on (not used for mono-colors) The meaning of each pair of bits for switches or buttons is: 00 - not pressed if button 01 - up or right switch position, or pressed if button 10 - down or left switch position 11 - middle switch position The definition of colors and/or on/off switch values will be defined in the product specific MIB. This may be cached at the chassis level. Conventions proposed 1/18/2006 for common reuse and consistency. 1. Use values of 0 for Black, 1 for Green, 2 for Red and 3 for Yellow, which maps to the OID definition of Green for color A, Red for color B, and Yellow for Both on. 2. The MIB is not specific about multi-column LED displays, so follow the common convention of Left column first, followed by Right column, always top to bottom as the MIB requires. 3. Blink is occasionally desired, but impossible to implement effectively for rate or duty cycle on raster graphic GUIs. Alternate the status value on successive SNMP gets if the bit has changed state multiple times. This will simulate the changing of state even though the frequency cannot be represented accurately.
