Chapter 33 Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create a table map:
Command
Step 1
configure terminal
Step 2
table-map table-map-name
Step 3
map from from-value to to-value
Step 4 default {default-value | copy | ignore}
Step 5
end
Step 6 show table-map [table-map-name]
Step 7 copy running-config startup-config
To delete a table map, use the no table-map table-map-name global configuration command.
This example shows how to create a DSCP-to-CoS table map. A complete table would typically include
additional map statements for the higher DSCP values. The default of 4 in this table means that
unmapped DSCP values will be assigned a CoS value of 4.
Switch(config)# table-map dscp-to-cos
Switch(config-tablemap)# map from 1 to 1
Switch(config-tablemap)# map from 2 to 1
Switch(config-tablemap)# map from 3 to 1
Switch(config-tablemap)# map from 4 to 2
Switch(config-tablemap)# map from 5 to 2
Switch(config-tablemap)# map from 6 to 3
Switch(config-tablemap)# default 4
Switch(config-tablemap)# end
Switch# show table-map dscp-to-cos

Purpose
Enter global configuration mode.
Create a table map by entering a table-map name and entering table-map
configuration mode.
Enter the mapping values to be included in the table. For example, if the
table map is a DSCP-to-CoS table map, the from-value would be the
DSCP value and the to_value would be the CoS value. Both ranges are
from 0 to 63.
Enter this command multiple times to include all the values that you want
to map.
Set the default behavior for a value not found in the table map.
• Enter a default-value to specify a certain value. For example, in a
DSCP-to-CoS table map, this would be a specific CoS value to apply
to all unmapped DSCP values. The range is from 0 to 63.
Enter copy to map unmapped values to an equivalent value. In a
•
DSCP-to-CoS table map, this command maps all unmapped DSCP
values to the equivalent CoS value.
Enter ignore to leave unmapped values unchanged. In a
•
DSCP-to-CoS table map, the switch does not change the CoS value
of unmapped DSCP values.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
