[j-nsp] Trouble with 100G link MX204 <-> Dell S4100F-ON

[Emmanuel Halbwachs]

Hello,

By chance, have somebody on this list succeeded in connecting at 100G a
MX204 to a Dell S4100-ON series ?

I didn't succeed.

MX204 <-> MX204 is OK.
Dell S4100 <-> Dell S4100 is OK.
MX204 <-> Dell S4100 is not OK...

I'm using the same brand of (compatible) QSFP28 10G-SR4. They just
differ by firmware tagging, but both Junos and DNOS accept foreign
transceivers anyway.

Cable is 12 FO multimode MTP, same for all tests.

Dell are at lastest version and MX204 are at 17.4.

If someone has a clue, It will be most welcome.

Next step is to ask both supports, but I fear ping-pong.

Have a nice week-end,
