SFP EEPROM

Tool to parse SFP eeprom contents

Libray use

[1] pry(#<SFPEEPROM>)> transceiver
=>          Transceiver => Ethernet - 1000BASE-LX (8859418881)
                     => FC Link Length - long distance (L)
                     => FC Technology - Longwave Laser (LL)
                     => FC Media - Single Mode (SM)
                     => FC Speed - 100 MBytes/sec

[2] pry(#<SFPEEPROM>)> transceiver.bit31
=> false
[3] pry(#<SFPEEPROM>)> transceiver.bit31 = true
=> true
[4] pry(#<SFPEEPROM>)> transceiver
=>          Transceiver => Infiniband - 1X Copper Active (144115196935274753)
                     => Ethernet - 1000BASE-LX
                     => FC Link Length - long distance (L)
                     => FC Technology - Longwave Laser (LL)
                     => FC Media - Single Mode (SM)
                     => FC Speed - 100 MBytes/sec

CLI use

[[email protected] ~/sfp_eeprom]% ./bin/sfp_eeprom data
          Identifier => SFP or SFP+ (3)
 Extended_Identifier => GBIC/SFP function is defined by two-wire interface ID only (4)
           Connector => LC (Lucent Connector) (7)
         Transceiver => Ethernet - 1000BASE-LX (8859418881)
                     => FC Link Length - long distance (L)
                     => FC Technology - Longwave Laser (LL)
                     => FC Media - Single Mode (SM)
                     => FC Speed - 100 MBytes/sec

Todo

Add all of the datafields in datafields directory. All of the datafields are loaded auomatically, so no need to touch other parts of the code when adding new datafield, just add new datafields file
