This should be easy. I need to configure sub-interfaces.Here is the error message I am getting saying that only "unit 0 can be used for this type of encapsulation". I tried to setting flexible vlan tagging first on the physical interface and then got a different error message. I attached that error message as well.Thanks to those who have helped me already on other posts. I greatly appreciate it and am really grateful for this platform. FamFeld
