Troubleshooting 10 Gb SFP+ transceiver detection (Sophos XGS 136)

Hello John,

Ports F1 and F2 on a XGS 136 are SFP-Ports (without +), so they will only accept 1 GBit SFP transceivers.

There is a known issue with auto-negotiation on SFP-ports, so you should manually configure this to the same settings on both ends.

Hi Philipp,

Thank you for your answer. Interestingly the 3rd party vendor that sold me the unit even quoted with 10Gb SFP+ transceiver (ITFZTCHXF) so I've incorrectly assumed it supports 10Gb connections.

When I look at the advanced settings of each physical port, the highest speed I can see is 1000Mbs Full-Duplex (Ports 1 to 12 and Port F1 and F2)

However if I go to  https://www.sophos.com/en-us/products/next-gen-firewall/tech-specs#XGSDesktop I can see that some models support 10Gb copper ports.

I can't tell for sure if the model I have can support 10Gb connections, other than what I can see in the advances settings

Hello John,

you misread this: it is 10x GE ports, that is ten ports with 1GBE on a model XGS136

Great. Thanks for pointing that out. Looks like I have to get an 1Gb SFP transceiver after all to use ports F1 and F2
