Example
The following example shows how to enable IP precedence mapping
globally:
Console(config)#map ip precedence
Console(config)#
map ip precedence (Interface Configuration)
This command sets IP precedence priority (i.e., IP Type of Service
priority). Use the no form to restore the default table.
Syntax
map ip precedence ip-precedence-value cos cos-value
no map ip precedence
• precedence-value - 3-bit precedence value. (Range: 0-7)
• cos-value - Class-of-Service value (Range: 0-7)
Default Setting
The list below shows the default priority mapping.
IP Precedence Value
CoS Value
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.
