When you enable port security on an interface that is also configured with a voice VLAN, what is the maximum
number of secure MAC addresses that should be set on the port?
A.
No more than one secure MAC address should be set
B.
The default is set
C.
The IP phone should use a dedicated port, therefore only one MAC address is needed per port
D.
No value is needed if the switchport priority extend command is configured
E.
No more than two secure MAC addresses should be set
Answer E is not correct, because the default is set. The default is one and no more than one secure MAC addresses should be set automatically.
Answer B seems to be the best answer
After enable port security on an interface that is also configured with a voice VLAN, the maximum number of MAC addresses that should be set by default on the port is 1.
When you enable port security on this interface, you must set the maximum allowed secure addresses on the port to at least two. Otherwise the selected Violation Mode will be activated, because the switch doesn’t set the maximum number of Mac´s on the port automatically to two.
the “maximum number of secure MAC addresses” is in relation to the show port-security interface interface-id command.
In the following example the interface is also configured with a voice VLAN but still the default number of secure MAC addresses will be set :
show port-security interface interface-id
Port Security : Enabled
Port Status : Secure-down
Violation Mode : Shutdown
Aging Time : 0 mins
Aging Type : Absolute
SecureStatic Address Aging : Disabled
Maximum MAC Addresses : 1
Total MAC Addresses : 0
Configured MAC Addresses : 0
Sticky MAC Addresses : 0
Last Source Address:Vlan : 0000.0000.0000:0
Security Violation Count : 0
feedback is desired
I’m sorry I’ve misunderstood the question
the correct answer is E
No more than two secure MAC addresses should be set
Mr. Nurhani,
If u enable voice vlan and port security, the default allowed is 1 (it would not automatically set to 2). Therefore you need to set allowed the MAC to 2.
I hope it clears you.
