Priority Commands ((Layer 3 and 4)- Cont.)
Command Function
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
Mapping IP Precedence Values
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)#interface ethernet 1/5
Console(config-if)#map ip precedence 1 cos 0
Console(config-if)#
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 Prece-
dence or IP DSCP, and default switchport priority.
IP Precedence and IP DSCP cannot both be enabled. Enabling one of these
priority types will automatically disable the other type.
Example: The following example shows how to enable IP DSCP mapping
globally:
Console(config)#map ip dscp
Console(config)#
