When connecting SFPs on the EX4650 we may found some issues under the Mist management, we will treat a possible scenario here

• SFP works fine on other device
• Port lights work fine
• No ET interface is created from the CLI

When we reviewed the configuration, we found that under “Additional CLI Commands” there was a setting causing a conflict.

This setting prevents the ET interface from being created, which in turn prevents the port from functioning properly.

Once this setting was removed, the port worked as expected.
