Note that a secure port has the following restrictions:
• It should not be connected to a network interconnection device.
• It cannot be configured as a member of a static trunk.
• It can be configured as an LACP trunk port, but the switch does not
allow the LACP trunk to be encabled.
NOTICE: A port that is already configured as a LACP or static trunk port
cannot be enabled as a secure port.

• Security Status — Enables or disables port security on the port.
(Default: Disabled)
• Intrusion Shutdown and Trap — Indicates the action to be taken
when a port security violation is detected:
– None: Indicates that no action should be taken. (This is the
default.)
Trap: Indicates that only an SNMP trap message be sent.
–
– Shutdown: Indicates that only the port should be disabled.
– Trap and Shutdown: Indicates that the port should be disabled
and an SNMP trap message sent.
NOTICE: If a port is disabled due to a security violation, it must be manually
re-enabled from the Ports/Port Configuration page. See "Switch 3248: Re-
