Configuring the Priority of Incoming Data Frames
You can connect a PC or other data device to a Cisco IP Phone port. To process tagged data traffic (in IEEE
802.1Q or IEEE 802.1p frames), you can configure the switch to send CDP packets to instruct the phone how
to send data packets from the device attached to the access port on the Cisco IP Phone. The PC can generate
packets with an assigned CoS value. You can configure the phone to not change (trust) or to override (not
trust) the priority of frames arriving on the phone port from connected devices.
Follow these steps to set the priority of data traffic received from the non-voice port on the Cisco IP Phone:
