Port Configuration Chapter 2 Port Isolation Function Configuration Chapter 2 Port Isolation Function Configuration 2.1 Introduction to Port Isolation Function Port isolation is an independent port-based function working in an inter-port way, which isolates flows of different ports from each other. With the help of port isolation, users can isolate ports within a VLAN to save VLAN resources and enhance network security. -

LACP should be mutually exclusive to Security and 802.1x ports. If a port has already enabled these two protocols, it won’t be allowed to use LACP. The following prompt will show up if there is any incorrect configuration while creating a PortChannel.
