Solution:
Because the XGS3-24242 is 1000Base-X force mode on port 13 ~ 24 in default value. In such circumstance, we would suggest to pre-setup the port(s) that is going to attach 10/100/1000Base-T copper in the CLI, please refer to example as below.
Example:
Set Port 13 ~ 24 that support 10/100/1000Base-T copper.
XGS3-24242(config)#interface ethernet 1/0/13-24 |
