Even rev2 is old. The actual are rev3.Sorry for digging up this thread. Meanwhile the RJ10 product page lists the new revision as also supporting jumbo frames (the old one did not).
I have 3 rev1 modules and 1 rev2 (happely working together). Is there a way to trade/flash/... the rev1 modules to rev2?
I have no r3. I have r1 and r2. r2 did show some more sfp info. Both can't handle frames big enough for mpls. Don't remember exactly but I think it was 1504 byte frames max. Test if you are able to handle bigger packets.Interesting, I had a discussion about this after my CRS309 video last week. I was testing, including jumbo frames and it was working fine and he said it was impossible.
All that I can add to this discussion is that module revision 2.11 manufactured 2018-12-06 works well. Tested it with 1Gbit Intel NIC connections (GUI reports 1Gbit connection in status window) and 10Gbit connections through 35m of CAT7 to an Intel x540 with full 10Gbit speed. I also inserted the S+RJ10 into a Mellanox ConnextX-3 and in there I was also able to get the full 10Gbit connected to a S+RJ10 in the CRS309.
I know hardware manufacturers don't like to do this but if Mikrotik could put up a list on the S+RJ10 information page what changed with what revision, it would prevent a whole lot of troubleshooting and testing!
p.s. My serial number ends with r2, does that mean it's a revision 2? Or is this the revision 3 you mentioned because it's the newest version I see posted here and the date is quite "young".
You can distinguish new S+Rj10 revision by “/r2” at the end of the serial number.
There shouldn't be any issues with passing Jumbo frames, if modules are from r2 revision. Please send us email, describing your setup and problem in more detail, at firstname.lastname@example.org
Someone in the forum used small memory heatsinks. Give it a search, and you will find it. It was an SFP+ (I think it was SFP+) port overheating.Is there a way to cool them down to a normal temperature? I put two more fans into the CRS but 1 or 2 degrees is nothing in this situation... Maybe a peltier...
So if they negotiate down to 1G they no longer transport Jumbo Frames? Difficult to find the problem if that happens ...I can confirm my S+RJ10 module (R2 18/12/06 shown on label and R2.11 shown on SFP tab in ROS) allows jumbo frame of 9000 at link speed of 2.5Gbps.
