Usage guidelines
In autoLearn mode, this command sets the maximum number of secure MAC addresses (both configured
and automatically learned) on the port. The maximum number set by this command cannot be smaller
than the current number of MAC addresses saved on the port.
In any other mode that enables 802.1X, MAC authentication, or both, this command sets the maximum
number of authenticated MAC addresses on the port. The actual maximum number of concurrent users
that the port accepts equals this limit or the authentication method's limit on the number of concurrent
users, whichever is smaller. For example, in userLoginSecureExt mode, if 802.1X allows less concurrent
users than port security's limit on the number of MAC addresses, port security's limit takes effect.
You cannot change port security's limit on the number of MAC addresses when the port is operating in
autoLearn mode.
Examples
# Set port security's limit on the number of MAC addresses to 100 on port GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 3/0/1
