Does "incompatible SFP" mean wrong GBICs?

I've just got my first 16Gb FC switch; it's licensed for all ports at 16Gb.

Four ports that should have been syncing at 16Gb were instead syncing at 8Gb.  I forced the ports to 16Gb, and a "switchshow" then said "incompatible SFP:

  40  40   012800   id    16G   Mod_Inv     FC  "Speed Mismatch / Incompatible SFP"

  41  41   012900   id    16G   Mod_Inv     FC  "Speed Mismatch / Incompatible SFP"

  42  42   012a00   id    16G   Mod_Inv     FC  "Speed Mismatch / Incompatible SFP"

  43  43   012b00   id    16G   Mod_Inv     FC  "Speed Mismatch / Incompatible SFP"

Does this mean I have the wrong GBICs?

Hi,

It looks that you have 8G SFPs. You can execute sfpshow <slot/port> to see the model and speed of the SFP.

btw, "gbic" means "GigaBit Interface Converter" so that's why the modules are called "sfp" since 2gb

SFP, stand for = small form factor pluggable

no matter if the Module is Ethernet or FC and/or whatever a Speed.

In my heart it will always be a GBIC
