Chapter 33 Configuring QoS
Configuring QoS
Beginning in privileged EXEC mode, follow these steps to create a table map:
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
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
table-map
table-map-name
Create a table map by entering a table-map name and entering table-map
configuration mode.
Step 3
map from
from-value
to
to-value
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.
Step 4
default
{
default-value
|
copy
|
ignore
}
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.
Step 5
end
Return to privileged EXEC mode.
Step 6
show table-map
[
table-map-name
]
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
