 Summit X695 switch and 10 Gbps SFP+ modules.

We have a Summit X695, running ONIE- with 10 Gbps SFP+ modules in it.  If we reboot this switch, then some of the ports do not come up after reboot.  We must manually disable and then re-enable these ports to make them work.

May I ask if anyone else sees this behaviour, please?

Hi Ambrose,

Are these with a specific model of 10G SFP+ modules? I want to see if I can replicate the behavior in the lab, so this could help me do so.

Hello Brad,

The part number is 10301.  The problem really is between the 10 Gbps SFP+ module in the X695 and the Dell 10 Gbps SFP+ module in a Dell server.  If the server is rebooted, then sometimes the link does not come up again, or it flaps, unless the port is disabled and then re-enabled after seven seconds.

If the switch ports are disabled and then re-enabled, then the problem appears even when there is no reboot of the server.
