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.
Explanation:
Usually, an IP Phone needs two MAC addresses, one for the voice vlan and one for the
access vlan. If you don’t want other devices to access this port then you should not set more
than two secure MAC addresses.
Below is an example for this configuration:(For more information about this, please read
