Configuring an interface to trust packet priority for
priority mapping
You can configure the switch to trust a particular priority field carried in packets for priority mapping
on interfaces.
When you configure the following 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.
• none—Uses the port priority as the 802.1p priority for mapping.
To configure the trusted packet priority type on an interface:
Step Command Remarks
