Configuring the Maximum Number of MAC Address Authentication Users Allowed to
Access a Port
You can configure the maximum number of MAC address authentication users for a port in order to
control the maximum number of users accessing a port. After the number of access users has
exceeded the configured maximum number, the device will not trigger MAC address authentication for
subsequent access users, and thus these subsequent access users cannot access the network
normally.
Follow these steps to configure the maximum number of MAC address authentication users allowed to
access a port:

Required
By default, the maximum number of
MAC address authentication users
allowed to access a port is 256.
z
If both the limit on the number of MAC address authentication users and the limit on the number of
users configured in the port security function are configured for a port, the smaller value of the two
configured limits is adopted as the maximum number of MAC address authentication users allowed
to access this port. Refer to Port Security in H3C WX3000 Series Unified Switches Switching
Engine Configuration Guide for the description on the port security function.
z
You cannot configure the maximum number of MAC address authentication users for a port if any
user connected to this port is online.
