Issue with SFP+ Transceiver in CRS317-1G-16S+

Thu Feb 28, 2019 4:53 am

I have several mikrotik/RB products. Currently I have a CRS326-24G-2S+ as my perimeter firewall, I have a CSS326-24G-2S+ in my office connected via Avago afbr-709smz transceivers, which are 10Gb 850nm Multimode fiber optic. This is working.

Now I've added a CRS317-1G-16S+, and when I move the transceiver from the CRS326 into the CRS317 it won't link/work.

When I issue the command
monitor sfp-sfpplus1
this is what it reports.

Why does it report
sfp-type: (unknown)
? What can I do to get it working.

I have upgraded/updated all devices to v6.44. All devices are fairly new (less than 6 months old.

I know it sounds silly but did you try putting SFP in different port or just unplugging and plugging it again more rapidly? I sometimes have such behavior when I connect SFP too slowly and not all pins make contact or something. Basically my CRS317 randomly behaves like this and unplugging + plugging again always solves an issue. You could try different interface as well. And make sure you have recent BOTH software AND firmware (/system package up install, /system routerboard upgrade)

Sometimes it's also worth to try connecting SFP with and without cable attached.

Yes I have tried all that. I ended up ordering a Transceiver that said it was compatible with mikrotik.

I can recommend FS.COM optical modules (copper ones are not that good tho) since they work quite well with MikroTik and seem to be affordable. Also their 1G optical modules actually work with autonegotiation enabled in SFP+ ports despite wiki claiming that disabling autoneg is necessary in this scenario, so it's quite nice (copper ones don't tho).
