Set Ciscodp Port - Enterasys Matrix 2G4072-52 Configuration Manual

Discovery Protocols Command Set
Cisco Discovery Protocol
3.2.3.6

set ciscodp port

Use this command to set the status, voice VLAN, extended trust mode, and CoS priority for
untrusted traffic for the Cisco Discovery Protocol on one or more ports.
set ciscodp port { [status {disable | enable}] [ vvid {<vlan-id> | none | dot1p |
untagged}] [trust-ext {trusted | untrusted}] [cos-ext value] } <port-string>
The following points describe how the Cisco DP extended trust settings work on the Matrix device.
•
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 (with the trust-ext trusted
parameter of this command), 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 cos-ext
parameter of this command.
•
There is a one-to-one correlation between the value set with the cos-ext parameter and the
802.1p value assigned to ingressed traffic by the Cisco IP phone. A value of 0 equates to an
802.1p priority of 0. Therefore, a value of 7 is given the highest priority.
NOTE: The Cisco Discovery Protocol must be globally enabled using the set ciscodp
status command as described in
on individual ports.
