When I have a Polycom VOIP phone plugged into a Cisco switch and a laptop plugged into the Polycom phone I get the following.
1) The phone goes into the voice VLAN as expected.
2) The laptop goes into the data VLAN as expected.
3) When I run show mac-address-table
on the Cisco switch I get the Polycom's MAC address listed twice, as belonging to both VLAN's.
4) When I run show ip arp
on the Cisco switch I get two IP's and two MAC's listed for the Polycom phone and the laptop.
I have the following questions:
1) Given that the Polycom phone is just an Ethernet bridge why is it that the MAC detection fails to catch the laptop's MAC address?
2) How can I fix that if at all?
The bigger picture is that I am trying to get PacketFence to view and manage the two devices (the phone and the laptop) individually and the way it is it just does not seem to be possible.
Any help much appreciated.
