◆
A secure port has the following restrictions:
■
It cannot be used as a member of a static or dynamic trunk.
■
It should not be connected to a network interconnection device.
◆
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.
◆
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 129 ).

is detected:
■

■
Trap : Send an SNMP trap message.
■
Shutdown : Disable the port.
■
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)
The maximum address count is effective when port security is enabled
or disabled, but can only be set when Security Status is disabled.
