Chelsio T520-CR problem
-
@stephenw10 Auto-select is on, flow control is off. We can see light at the switch but the T520 just won't talk.
-
Ok try disabling flow control then since it doesn't appear to be negotiating.
-
@stephenw10 Flow control is already disabled.
To be specific, auto-negotiation is off on the switch. It's enabled in the firewall interface. I've tried manually selecting the speed but same results.
-
<full-duplex,rxpause,txpause>this indicates flow-control is enabled. -
@stephenw10 added hw.cxgbe.pause_settings="0" to /boot/loader.conf but same results
-
Can you not set it in the interface config since it's a mediaopt in cxl?
Can you change the switch side settings?
Do you have anything besides the switch you can test linking it with?

@stephenw10 One of the first changes I made was to explicitly set the speed and duplex mode on these interfaces directly in the GUI. We can change anything, and have been trying. We have the Arista, a Mikrotik, and a Juniper. We have another Dell server with T440 cards that links right up with all of these switches.
-
Mmm, to a 10G switch I expect it to link up in the default mode. You usually only need to set a fixed speed/duplex to connect at 1G.
But does it not offer you all the medioopt types in the webgui? That's where I would expect to set full-duplex without flow control.

@stephenw10 Yes, there's a list of 8 options plus auto-detection. One of those options is "10Gbase-LR full-duplex" with no tx/rx pause. I've tried using this setting.
-
Do the switches show any error?
Does it link directly to the Dell server maybe?
-
@stephenw10 Had to put this to the side for a bit, but I'll return to troubleshooting at a later date.
