Configuring a port to trust packet priority for priority
mapping
You can configure the device to trust a particular priority field carried in packets for priority mapping on
ports or globally.
When you configure the trusted packet priority type on an interface, use the following available
keywords:
•
dot1p
—Uses the 802.1p priority of received packets for mapping.
•
dscp
—Uses the DSCP precedence of received IP packets for mapping.
•
Trust no packet priority
—Uses the port priority as the 802.1p priority for mapping.
