Required 

By default, a port operates in 
noRestriction mode. In this 
mode, access to the port is not 
restricted. 

You can set a port security 
mode as needed. 

 

z 

Before setting the port security mode to autolearn, you need to set the maximum number of MAC 

addresses allowed on the port with the port-security max-mac-count command.  

z 

After you set the port security mode to autolearn, you cannot configure any static or blackhole 

MAC addresses on the port.  

z 

If the port is in a security mode other than noRestriction, before you can change the port security 

mode, you need to restore the port security mode to noRestriction with the undo port-security 

port-mode command. 

 

If the port-security port-mode mode command has been executed on a port, none of the following can 

be configured on the same port: 

z 

Maximum number of MAC addresses that the port can learn 

z 

Reflector port for port mirroring 

z 

Link aggregation

Be default, NTK is disabled on 
a port, namely all frames are 
allowed to be sent.
