4-2064
Example
The following example shows how to enable IP precedence mapping globally:
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.
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:
Console(config)#map ip precedence
Console(config)#
Table4-66 Mapping IP Precedence Values
IP Precedence Value 01234567
CoS Value 01234567
Console(config)#interface ethernet 1/5
Console(config-if)#map ip precedence 1 cos 0
Console(config-if)#
