EN4093R internal ports interface connectivity question

Dear Support,

When Server SN550 Side (installed with Redhat Linux) performed shutdown those two 10G Ethernet port , Flex System EN4093R Switch Module side do not detect the corresponding interface port down (in connected state).  Is it normal or need perform setting on EN4093R?

It works as design between emulex nic (cn4052s,cn4054s,etc) and ethernet module on flex system.

You will see link down/up for Qlogic nic( en4172,cn4022)on legacy flex system.

It's difference between Emulex nic and Qlogic nic ,but they both work as design .

Daniel,

Many thx reply, btw, how about Intel 10G ethernet card 7M27A03927 Fabric connector?  is it shown with link up/down if shutdown ports?

Others will reflect the down/up event on switch side except emulex nic.

No documentation is found for that , I just get that from lab testing result.

Many thx, is that meant except emulex, other brand like Intel should show it up/down in the internal network?
