Fortigate 1801F and supported SFP+ "Tengig"

[MORAMADAN]

Hello Bro,

               I have new deployment that include 1801F appliance and my question is that :

Does this appliance supports Cisco SFP "TenGig" tranceivers ? which part-IDs ? I have Few Cisco ones such as "Transceiver 10Gbase-SR PID: SFP-10G-SR-S" and I want to use if supported.

TIA to you all.

It would be a surprise to me if it doesn't work. So far I never experienced problems with Cisco/Cisco compatible SFPs and SFP+ putting on FGTs. Is it not working now?

But, since we need to buy a bunch when wen get a new FGTs anyway, we almost always need to buy new ones, a third-party FTNT compatible models, which is much cheaper than FTNT ones or Cisco ones.

hi,

we've ordered new FGT but we're short of SFP/transceivers for the HA. 

we got spare Cisco 10G-SR fiber SFPs that's why I asked if these will work on the FGT.

[Toshi_Esumi]

If you already have them you just need to try them, right? Then if they don't work, you have to order different ones. But at that time, I recommend FTNT compatible ones since you'll order new ones. I'm almost sure they just work fine though.
You spent a lot of money to get 18xxFs most of us can't afford. A dozen of SFPs/SFP+s are almost negligible.

By the way, when you test it with another device, like a switch, then doesn't work, don't blame this Cisco SFP+ on the FGT immediately. The other end might have  a compatibility issue unless its a Cisco switch + a Cisco SFP+.

We are using Cisco SFP+ 10g for ha ports, working fine "just notification on the interface" CISCO-OPLINK TPP4XGDS0CCISE3G

hi,

thanks for the confirmation!

i also did a quick test and cisco brand SFP is detected.

# get system interface transceiver port18
