Making sense of CGR 2010 Datasheet

[Cash]

I am hung up on a simple concept. For the CGR 2010, there are two SFP ports and two RJ45 ports native to the router. Are these ports a 1 for 1 kind of thing? If I use one SFP port, does it take away my ability to use one RJ45 and the same thing for if I were to use two SFP ports. My initial understanding was that there was one independent SFP port, one independent RJ45 port, and a shared connection between the other SFP and RJ45 port. Any guidance is appreciated.

Hello.

The WAN port on CGR2010 is combo. GE 0/1 and GE 0/2 can be SFP or RJ-45.

GE 0/1: SFP or RJ-45

GE 0/2: SFP or RJ-45
