This variable indicates the type of the SFP. It is a bitmap represented as a sum, therefore, it can represent multiple types (combination of types) simultaneously. The various bit positions are: bit 0 (1): 1000BASE-SX bit 1 (2): 1000BASE-LX bit 2 (4): 1000BASE-CX bit 3 (8): 1000BASE-T bit 4 (16): 100BASE-LX/LX10 bit 5 (32): 100BASE-FX bit 6 (64): BASE-BX10 bit 7 (128): BASE-PX bit 16 (65536): 2500BASE-SX bit 17 (131072): 2500BASE-LX bit 18 (262144): 2500BASE-BX If the expSfpType is unknown or not specified, expSfpType = 0.
