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.
