SMC Networks 16 10BASE-T, 100BASE-TX manual List below shows the default priority mapping

Priority Commands 4

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.

Table 4-60. Mapping IP Precedence Values

IP Precedence Value	0	1	2	3	4	5	6	7
CoS Value	0	1	2	3	4	5	6	7

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)#
