Multirate SFP+ in EX?

Feb 13, 2023, 7:23 AM

Post #1 of 4 (330 views)

I have an old Juniper EX4500 (working on replacing it), and some
FiberStore 10G/1G SFP+ modules (SFP-10GSR-85). When I put the SFP+ in
the EX, it sees it as a 1G module (so interface ge-0/0/X), but the other
end is 10G. Is there a way to force the EX end to 10G with the
multirate SFP+? I see set ether-options speed, but it'll only go to 1g
on the ge-foo interface; I can set xe-foo ether-options speed 10g but it
is ignored (since the EX doesn't think it has an xe-foo interface).

Not sure, but if there is a way, it might be configured under "set chassis pic ...", perhaps something like this:

sst chassis pic fpc-slot 0 pic-slot 1 port 0 speed 10g

Looks like there's no "set chassis pic ..." anything on this. The only
thing close, "set chassis fpc 0 pic 0 ..." is for turning the modular
PIC (like on the EX4200) between 1G and 10G mode, but not individual
ports.

We've got some similar Flexoptix 1G/10G "multirate" optics and as far as
I'm aware you have to code them as 1G or 10G with their coding box. You
can't set anything in the chassis to force them to 1G or 10G.
