1G Copper SFP on M4300-8X8F Odd Behavior
I am having trouble with some 1G copper SFPs in a M4300-8X8F (XSM4316S) switch (I actually have two of these switches and both of them have the same problem with these SFPs) and was wondering if som...
Hi dentspen,
Welcome to the community!
Could you please run below CLI command when you insert the fiber module?(assume the port 1/0/1)
show fiber-ports optics 1/0/1
show fiber-ports optics-info 1/0/1
show fiber-ports optics-eeprom 1/0/1
show running-config interface 1/0/1
Regards,

I'm not sure if you wanted the information on the Copper SFP I am having problems with or the Fiber SFP+ that I mentioned, so I am going to provide the output for a port with a fiber SFP and a port with a copper SFP so that you can see both. I apologize for my confusion.
Port 1/0/1 (contains a 10G Fiber SFP+)
This is the type of SFP that DOES work

Hi dentspen,
Sorry to make you confusion.
I just want to get the info for the issue port. I mean please insert the fiber module and cable to the issue port, and then run the command to get the detailed info.
Thanks.
Thank you for your response, Retired_Member,
The issue I have is with a Copper Ethernet (RJ45) SFP module, not with a fiber module. I have plugged the copper module into port 1/0/2. Here are the outputs from the commands that you asked for:

Thanks for your helpOk, understand.
Just correct, SFP is only for Fiber module type, if it's copper, we just say copper cable(cat5 or cat6). And for copper cable, it's no speed concept, just based two device negotiate.
Any way, let's check with the copper port.
As all port of M4300-8X8F is support 10G speed, if you connect to 1G port, it also can up with 1G speed, but the light is orange, not green(only when up with 10G speed, it will show green).
So could you please run command as 'show port 1/0/2', and we can check the port speed.
