When configuring port security on a Cisco Catalyst switch port, what is the default action
taken by the switch if a violation occurs?
A.
protect (drop packets with unknown source addresses)
B.
restrict (increment SecurityViolation counter)
C.
shut down (access or trunk port)
D.
transition (the access port to a trunking port)
PortSecurity cannot be applied on trunk ports, can you ?
Trunk port security extends port security to trunk ports. It restricts the allowed MAC addresses or the
maximum number of MAC addresses to individual VLANs on a trunk port. Trunk port security enables
service providers to block the access from a station with a different MAC address than the ones specified
for that VLAN on that trunk port. When a trunk port security violation occurs, the trunk port is shut down
and an SNMP trap may be generated. Trunk port security is also supported on private VLAN trunk ports
