Hi Gents,

I've tried to use Cisco GLC-T SFP's with the new CCR 2004 and faced some issues.

The Cisco GLC-T are compatible with Mikrotik routers (I have read it somewhere) and they should be able to work on 10/100/1000.
No issue if I set them to 1Gb or use it with auto and 1G link, but they not work with 100Mb links and cant be set to 100Mb.
Even if I disable Auto Negotiation and set it to 100Mb the status stays on 1Gb and no link.
Unfortunately some of devices used are rated only to 100Mb connectivity and they cannot connect on 1G.
This puts back my plans to upgrade a site.

Can someone shed some light why I cant set the SFP module to 100Mb on CCR 2004?
Maybe is just incompatibility with this SFP modules?
Does using Microtik's SFP S-RJ01 will solve the issue?
Any advice is appreciated.

Well,
I have changed the SFPs with Mikrotik ones but I still cannot set them to work on 100MB.
This makes connecting some legacy devices problematic and seems to be an issue - not all legacy devices can be changed due our liking.
Please advice if there's solution for this issue.

I have a CCR1009. The 10gig copper module in the sfp+ port DOES NOT WORK with my ISPs (both a standard plain ethernet cable connection nor a bell fibre connection). This is with a MT module not another brands. I dont think I have tried it (with MY ISPs) with the SFP copper cage as that is connected to MT switches. Not impressed.
