Supported Phones
When you use SmartPorts with the ciscoipphone keyword, some of the QoS configuration requires
phone-specific configuration (trust-ext, ext-cos) which is supported only on the following phones: Cisco
IP Phone 7910, Cisco IP Phone 7940, Cisco IP Phone 7960, and Cisco IP Phone 7935. However, the
ciscoipphone keyword is not exclusive to these models only; any phone can benefit from all the other
QoS settings that are configured on the switch.
The Cisco SoftPhone is supported through the ciscoipsoftphone keyword.
CDP Dependencies
To configure the QoS settings and the trusted boundary on the Cisco IP Phone, you must enable CDP
version 2 or later on the port.
You need to enable CDP only for the ciscoipphone QoS configuration; CDP does not affect the other
components of the SmartPorts feature.
EtherChannel Considerations
The SmartPorts commands do not support channeling.
PFC/PFC2 Support
No PFC or PFC2 is required for the ciscoipphone keyword. A PFC or PFC2 is required for the
ciscosoftphone keyword.
Module Support
The ciscoipphone keyword is supported only on the 10/100 and 10/100/1000 Ethernet ports.
The ciscosoftphone keyword is supported on all Ethernet ports.
