Configuring Port Security
– 312 –
COMMAND USAGE
â—† A secure port has the following restrictions:
â–
It cannot be used as a member of a static or dynamic trunk.
â–
It should not be connected to a network interconnection device.
â—† The default maximum number of MAC addresses allowed on a secure
port is zero. You must configure a maximum address count from
1-1024 for the port to allow access.
â—† If a port is disabled (shut down) due to a security violation, it must be
manually re-enabled from the Interface > Port > General page
(page 125).
PARAMETERS
These parameters are displayed in the web interface:
◆ Port – Port number.
◆ Action – Indicates the action to be taken when a port security violation
is detected:
â–
None: No action should be taken. (This is the default.)
â–
Trap: Send an SNMP trap message.
â–
Shutdown: Disable the port.
â–
Trap and Shutdown: Send an SNMP trap message and disable the
port.
◆ Security Status – Enables or disables port security on the port.
(Default: Disabled)
◆ Max MAC Count – The maximum number of MAC addresses that can
be learned on a port. (Range: 0-1024, where 0 means disabled)
