Parameters
count-value: Specifies the maximum number of secure MAC addresses that port security allows on the
port. The value ranges from 1 to 1024. Make sure this value is no less than the number of MAC addresses
currently saved on the port.
Usage guidelines
In autoLearn mode, this command sets the maximum number of secure MAC addresses (both configured
and automatically learned) 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.
Examples
# Set the maximum number of secure MAC address port security allows on port Ten-GigabitEthernet
1/0/1 to 100.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port-security max-mac-count 100
