And this one:

QUESTION 146
A question related to security violation mode which drop unknown packets and then sends trap.

A. inhibit
B. drop
C. restrict
D. shutdown
E. protect

Correct Answer: C

Should this one be D? only D send trap; and put the interface into err-disable state (which means the unknown packets are dropped too)

QUESTION 146

又仔细Google了一下，有的说C只计数，不送Trap，有的说C既计数又送Trap，前提是SNMP default送Trap：
“Restrict—A port security violation restricts data, causes the SecurityViolation counter to increment, and causes an SNMP Notification to be generated. The rate at which SNMP traps are generated can be controlled by the snmp-server enable traps port-security trap-rate command. The default value ("0") causes an SNMP trap to be generated for every security violation.”

所以结论是，还是选C吧：-D

Catalyst 6500 的说明手册上对于Restrit的描述根本没提发送SNMP Trap，只有Shutdown提了:

•protect—The PFC drops packets with unknown source addresses until you remove a sufficient number of secure MAC addresses to drop below the maximum value.

•restrict—The PFC drops packets with unknown source addresses until you remove a sufficient number of secure MAC addresses to drop below the maximum value and causes the security violation counter to increment.

•shutdown—Puts the interface into the error-disabled state immediately and sends an SNMP trap notification.
