Command Usage
This command enables the attachment of multiple clients to a single
802.1X-enabled port.
If you use this command without the authentication keyword, only one of the
attached hosts must be successfully authorized for all hosts to be granted
network access. If the port becomes unauthorized, all attached clients are
denied access to the network.
If you use this command with the authentication keyword, each host must be
successfully authorized in order to grant network access. Please note that
packets are NOT encrypted, and after success full authentication filtering is
based on the source MAC address only.
For unauthenticated VLANs multiple hosts are always enabled.
Port security on a port cannot be enabled if the port if multiple hosts are
disabled or multiple hosts are enabled with authentication per host.
