Default Setting
The list below shows the default priority mapping.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• The precedence for priority mapping is IP Port, IP Precedence or IP DSCP,
and default switchport priority.
• IP Precedence values are mapped to default Class of Service values on a
one-to-one basis according to recommendations in the IEEE 802.1p standard,
and then subsequently mapped to the eight hardware priority queues.
• This command sets the IP Precedence for all interfaces.
Example
The following example shows how to map IP precedence value 1 to CoS value 0:
map ip dscp (Global Configuration)
This command enables IP DSCP mapping (i.e., Differentiated Services Code Point
mapping). Use the no form to disable IP DSCP mapping.
Syntax
[no] map ip dscp
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
• The precedence for priority mapping is IP Port, IP Precedence or IP DSCP,
and default switchport priority.

priority types will automatically disable the other type.
