edit the SIP<MAC>.cnf

network_port2_type = Hub/Switch

 (Optional) Configures the device type that is connected to port 2 of 
the phone.

Valid values are Hub/Switch and PC. Default is Hub/Switch.
Note If the value is PC, port 2 can be connected only to a PC. If you 
are not sure about the connection, use the Hub/Switch default value. 
Specifying the PC option and then connecting port 2 to a switch results 
in spanning-tree loops and network confusion.
