Celestica Seastone DX-010 no-carrier on 100gig

[rganapa]

when the speed is set to 40gig the link comes on a 40gig optic
However with 100gig optic, there is no link

sfputil doesn't know about 100gig compliance as there is no code print info for

I have the same issue - have you ever found a solution?

[stormwindy]

Any updates for this? I have the same hardware setup with Sonic. I only want to connect two machines through the switch and I have no clue how to.

[RandGH]

I manged to get CX4 (and most of my other NICs) running with the Celestica switch by adjusting FEC auto-negotiation to RS instead of FC or none. With that setting the CX4's link up just fine with any brand of cable I tried.

[stormwindy]

@RandGH What command did you use to do the changes? I am very new to switch configurations, so I have no clue. Thanks.

Edit: For context I couldn't manage to get into configuration mode

[RandGH]

sudo portconfig -p Ethernet124 -s 100000 -f rs

[stormwindy]

@RandGH Sorry for bothering for an irrelevant topic but do you also know how to turn on auto-neg for interfaces?

[RandGH]

sorry, not without firing one up and checking, but shouldn't be that difficult to find ?

not sure it works at all though

Hi. Guys i have a question. Can I link one celestica seastone dx-010 QSFP28 100G port with Mikrotik 40 Gbps QSFP+ ? My target is to obtain 40Gbps link between this two products. If is possible can I use LR (10KM) qsfp ? Thanks
