Port security is a feature on switches that limits and identifies the MAC addresses allowed on a specific port, preventing unauthorized devices from accessing the network. It works only on access ports, which connect end devices to the switch, and is not supported on EtherChannel, private VLAN, or 802.1X authenticator interfaces .
Port isolation prevents traffic between specific ports, even within the same VLAN, while still allowing access to uplinks or the Internet. This is useful in multi-tenant environments or for security segmentation .
