Gents ,
I am looking for some clarification please . The doc CD says the following in reference to static Mac address’s in voice vlans .
When you enable port security on an interface that is also configured with a voice VLAN, you must set the maximum allowed secure addresses on the port to at least two plus the maximum number of secure addresses allowed on the access VLAN. When the port is connected to a Cisco IP phone, the IP phone requires up to two MAC addresses. The address of the IP phone is learned on the voice VLAN, and it might or might not be learned on the access VLAN. Connecting a PC to the IP phone requires additional MAC addresses
So lets say I am using DOT1Q Tagged frames and not DOT1P priority tagged frames
I have got 6 machines on this VLAN , (NO other phones. just PC’s) And there are two devices (phone and PC) on this port fa0/14
I would config as per , YES ?
Int fa0/14 Switchport port-security maximum 8 Switchport port-security mac-address 0000.0000.0000.0001 Switchport port-security mac-address 0000.0000.0000.0002
Many thanks
