SET SWITCH SECURITYMODE
Syntax
set switch
securitymode=automatic|limited|secure|locked
Parameter
securitymode Specifies the switch’s security mode. Options are:
automatic Disables port security on the switch. A
switch operating in Automatic mode
does not restrict the number of MAC
addresses learned by the ports. The
switch continues to learn addresses so
long as there is available space in the
MAC address table. This is the default
setting.
limited Sets the switch to the Limited security
mode. This mode allows you to specify
a maximum number of MAC addresses
each port can learn. To specify a port
limit, use the SET SWITCH THRESHOLD
command.
secure Sets the switch to the Secure security
mode. In this mode the switch forwards
frames based only on static MAC
addresses. After activating this security
mode, you must enter the static MAC
addresses of the nodes with frames the
switch is to forward. To add static MAC
addresses, use the ADD SWITCH FDB
command.
locked Sets the switch to the Local All Ports
security mode. This mode causes the
switch to stop learning new dynamic
MAC addresses. The switch forwards
frames based only on static MAC
addresses and on those dynamic
addresses it has already learned.
