Specifying the maximum authenticated MACs allowed on a port


aaa port-access mac-based [e] <port-list> [addr-limit <1-256>]

Specifies the maximum number of authenticated MACs to allow on the port.

Default: 1


On switches where MAC authenticated and 802.1X operate concurrently, this limit includes the total number of clients authenticated through both methods.

The limit of 256 clients only applies when there are fewer than 16,384 authentication clients on the entire switch. After the limit of 16, 384 clients is reached, no additional authentication clients are allowed on any port for any method.
