Port Security and Port Types
You can configure port security only on Layer 2 interfaces. Details about port security and different types of interfaces or ports are as follows:
* Access ports — You can configure port security on interfaces that you have configured as Layer 2 access ports. On an access port, port security applies only to the access VLAN.
* Trunk ports — You can configure port security on interfaces that you have configured as Layer 2 trunk ports. VLAN maximums are not useful for access ports. The device allows VLAN maximums only for VLANs associated with the trunk port.
* SPAN ports — You can configure port security on SPAN source ports but not on SPAN destination ports.
* Ethernet Port Channels — Port security is not supported on Ethernet port channels.
