Port Speeds for CBR2-T aka CBA4332COM

I have 2gbps internet service connected to a CBR2-T modem/router.

The device has 6 network ports.  What speeds do these port support?  I have one connected to my 10gbps switch and the connection negotiates to 1gbps.  Do these ports support 2.5gbps or 5.0gbps?

I can not find an only manual or detailed product description for the CBR2-T.

Without the ability to connect to my switch at a speed of at least 2.0gbps, I am not able to get the full benefit of my purchased connection speed.

That is for the CBR-T aka the CGA4131COM.  It is not the same unit as the CBR2-T (CGA4332COM).  For example the CBR-T has 8 ports and the CBR2-T has 6.

I also know the the CBR-T ports are only 1gbps capable.  

I am looking for information on the CBR2-T.

Thanks!

All you have to do is look at the back of the Modem. It tells you what each port it capable of

Unfortunately, that doesn't help anyone else here that would like to understand their modem better!

I'm a new Business customer with same model number (CBR2-T) and questions.


I'm also trying to optimize bandwidth via switch/router and network adapters.

I would like to start with reviewing hardware manual.

Please, share information here, if possible. Thanks in advance.

First 4 ports are 1Gbs and the last 2 are 2.5Gbs.
