• The precedence for priority mapping is IP Port, IP Precedence 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 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.

no map ip precedence
• precedence-value - 3-bit precedence value. (Range: 0-7)
• cos-value - Class-of-Service value (Range: 0-7)
