S5248 Interface with 2 port numbers
Hi all,
I've noticed that my switch has 2 physical ports labeled with 2 port numbers each. One of the physical ports is labeled 49 and 50. The other 51 and 52. I have an SFP plugged in, and when I run the check media command port 49 and 50 both report the same serial number. I'm assuming this port can be used to split that physical port into 2 ports via a break out cable? I'm just wanting to plug a single device in, so my question is how do I configure this thing? I've tried searching on the subject but I'm not really sure what this feature is even called. Any help would be greatly appreciated.
I want to connect a firewall to the switch using port 49 (or 50 which seems to be the same) using a QSFP+ 40GBASE-SR4. Do I configure port 49 and disable 50? Do I just configure both 49 and 50? How does having 2 interfaces on a physical port work if you're not breaking it out into 2 interfaces?

BBeardPHC,
To answer the question as to why they have the same serial number, it is due to 49 and 50 being in the same port group, as seen here.
Now in regards to your other questions, I think your configuration will work but port 50 won't be useable unless you use a breakout cable, based on page 93 here
Let me know if this helps.

Hi @BBeardPHC,
It depends on the end device that the port connecting to, what cable are you using and what is the end device's port information? Port 49, 50, 51, 52 are QSFP28-DD.
