Command Usage
• The command map ip precedence enables the feature on the switch. The command map ip precedence
precedence-value cos cos-queue maps IP Precedence values to port CoS queues.
• The precedence for priority mapping is IP Port, IP Precedence/DSCP/TOS, and default switchport priority.
• This command sets the IP Precedence priority for all interfaces.
• IP Precedence, IP DSCP, and IP TOS Priority cannot all be enabled at the same time. Enabling one of these priority
types automatically disables the others.
