1-2 

 describes the available port security modes. 

Table 1-1 Description of port security modes 

noRestriction 

Port security is disabled on the port and access to the port is 
not restricted. 

In this mode, 
neither the 
NTK nor the 
intrusion 
protection 
feature is 
triggered. 

autolearn 

In this mode, a port can learn a specified number of MAC 
addresses and save those addresses as secure MAC 
addresses.  

When the number of secure MAC addresses reaches the 
upper limit, the port changes to work in secure mode and 
permits only frames whose source MAC addresses are 
secure MAC addresses or static MAC addresses configured 
by using the mac-address static command. 

secure 

In this mode, the port is disabled from learning MAC 
addresses.  

Only those packets whose source MAC addresses are 
security MAC addresses learned and static or dynamic MAC 
addresses can pass through the port. 

In either mode, 
the device will 
trigger NTK 
and intrusion 
protection 
upon detecting 
an illegal 
packet. 

userlogin 

In this mode, port-based 802.1x authentication is performed 
for access users. 

In this mode, 
neither NTK 
nor intrusion 
protection will 
be triggered.
