This is applicable only for DSG9032 and DSG8064. For DSG9032, each 100G port can operate with 100G pluggable module or channelized to 4 25G sub-ports, or operate with 40G pluggable module or channelized to 4 10G sub-ports. For DSG8064, no channelized and 40G x 64 ports. Each octet string contains the value of a sub-port LED status. And use the ifIndex as the position starting from 192th octet. Such 192th octet for 1/1/1, 193 for 1/1/2, 196 for 1/2/1, so on so forth. The following shows the meaning for each byte: byte value DSG9032 meaning for activity 0 : port not valid or not present 1 Light Off : admin enabled without pluggable module 2 Slow Blinking Green : admin disable wtih/without 100G pluggable 3 Slow Blinking Amber : admin disable wtih 40G pluggable 4 Slow Blinking Blue : admin disable wtih 100G pluggable and channelized 5 Slow Blinking Pruple : admin disable wtih 40G pluggable and channelized 6 Solid Green : link up with 100G pluggable 7 Solid Amber : link up with 40G pluggable 8 Solid Blue : link up with 25G (channelized of 100G pluggable) 9 Solid Pruple : link up with 10G (channelized of 40G pluggable) 10 Random Blinking Green : link up & activity with 100G speed 11 Random Blinking Amber : link up & activity with 40G speed 12 Random Blinking Blue : link up & activity with 25G speed(channelized of 100G pluggable) 13 Random Blinking Pruple : link up & activity with 10G speed(channelized of 40G pluggable) byte value DSG8064 meaning for activity 0 : port not valid or not present 1 Light Off : admin enabled without pluggable module 2 Slow Blinking Green : admin disable wtih/without 40G pluggable 6 Solid Green : link up with 40G pluggable 7 Solid Amber : local fault 10 Random Blinking Green : link up & activity with 40G speed 11 Random Blinking Amber : remote fault
