Example:
Set the maximum secure MAC address number for port 1 to 4.
Switch(Config)#interface Ethernet 1/1
Switch(Config-Ethernet1/1)# port-security maximum 4
7.6.1.3.6 port-security timeout
Command:port-security timeout <value>
no port-security timeout
Function:
Set the timer for port locking; the “
no port-security timeout
” command
restores the default setting.
Parameter: < value>
is the timeout value, the valid range is 0 to 300s.
Command mode:
Interface Mode
Default:
Port locking timer is not enabled by default.
Usage Guide:
The port locking timer function is a dynamic MAC address locking function.
MAC address locking and conversion of dynamic MAC entries to secure address entries
will be performed on locking timer timeout. The MAC address binding function must be
enabled prior to running this command.
Example:
Set port1 locking timer to 30 seconds.
Switch(Config)#interface Ethernet 1/1
Switch(Config-Ethernet1/1)# port-security timeout 30
7.6.1.3.7 port-security violation
Command:port-security violation {protect | shutdown}
no port-security violation
Function:
Configure the port violation mode. The “
no port-security violation
” restore the
violation mode to protect
Command Mode:
Port mode
Parameter:protect
refers to protect mode;
shutdown
refers to shutdown mode
Default:
The port violation mode is
protect
by default
Usage Guide:
The port violation mode configuration is only available after the MAC
address binding function is enabled. when the port secure MAC address exceeds the
security MAC limit, if the violation mode is
protect
, the port only disable the dynamic
MAC address learning function; while the port will be shut if at
shutdown
mode. Users
can manually open the port with
no shutdown
command.
Example:
Set the violation mode of port 1 to shutdown
Switch(Config)#interface Ethernet 1/1
Switch(Config-Ethernet1/1)#port-security violation shutdown
7.6.1.3.8 show port-security
Command: show port-security
Function:
Display the secure MAC addresses of the port.
