Limiting the Number of Authenticated Hosts
You can limit the number of hosts that are authenticated at any one time by entering a command such as the following.
device(config-vlan-10-webauth)# host-max-num 300
You can specify from 0 through 8192 hosts. The default is 0. Specifying 0 means there is no limit to the number of hosts that can be authenticated. The maximum of 8192 is the maximum number of MAC addresses the device supports.
When the maximum number of hosts has been reached, the FastIron switch redirects any new host that has been authenticated successfully to the Maximum Host web page.
