hi , i want to ask about security in voice vlan .

plz have a look at command below :

===================

Switch(config-if)# switchport port-security maximum 20

Switch(config-if)# switchport port-security violation restrict

Switch(config-if)# switchport port-security mac-address sticky

Switch(config-if)# switchport port-security mac-address sticky 0000.0000.0002

Switch(config-if)# switchport port-security mac-address 0000.0000.0003

Switch(config-if)# switchport port-security mac-address sticky 0000.0000.0001 vlan voice

Switch(config-if)# switchport port-security mac-address 0000.0000.0004 vlan voice

Switch(config-if)# switchport port-security maximum 10 vlan access

Switch(config-if)# switchport port-security maximum 10 vlan voice

=======================

does the command :

#switchport port-security maximum 20

limit the maximum macs whatever it was  pc or phone to 20 ?

or

it just limit the max number of pc macs to 20 ?
