Example
This example shows how to enable the Cisco DP function on port ge.0.5:
3.2.6.12 set port ciscodp trust-ext
Use this command to set the trusted status of one or more switch ports connected to a Cisco IP 
phone. Note the following points describing how the Cisco DP trust settings work.
A Cisco DP port trust status of trusted or untrusted is only meaningful when a Cisco IP phone is 
connected to a switch port and a PC or other device is connected to the back of the Cisco IP 
phone. 
A Cisco DP port state of trusted or untrusted only affects tagged traffic transmitted by the device 
connected to the Cisco IP phone. Untagged traffic transmitted by the device connected to the 
Cisco IP phone is unaffected by this setting. 
If the switch port  is configured to a Cisco DP trust state of trusted (via this command, set port 
ciscodp trust-ext
), this setting is communicated to the Cisco IP phone instructing it to allow the 
device connected to it to transmit traffic containing any CoS or Layer 2 802.1p marking. 
If the switch port is configured to a Cisco DP trust state of untrusted, this setting is 
communicated to the Cisco IP phone instructing it to overwrite the 802.1p tag of traffic 
transmitted by the device connected to it to 0, by default, or to the value specified by the 
command set port ciscodp cos-ext.
There is a one-to-one correlation between the value set by the set port ciscodp cos-ext 
command (
) and the 802.1p value assigned to ingressed traffic by the Cisco IP 
phone. A classify-value of 0 equates to an 802.1p priority of 0 which is given lower priority than 
an 802.1p priority of 7. Therefore, a classify value of 7 is given the highest priority.
