Command History
Usage Guidelines This command sets the MPLS EXP value only in the topmost label. This command does not affect an IP
pa
cket. The MPLS field in the topmost label header is not changed.
Using This Command with the Enhanced Packet Marking Feature
If you are using this command as part of the Enhanced Packet Marking feature, you can use this
command to specify the qos-group packet-marking category to be used for mapping and setting the
differentiated services code point (DSCP) value.
mpls-exp-value Specifies the value used to set MPLS experimental bits defined by the
p
olicy map. Valid values are numbers from 0 to 7.
qos-group Specifies that the qos-
group packet-marking category is used to set
the MPLS EXP imposition value. If you are using a table map for
mapping and converting packet-marking values, this establishes the
“map from” packet-marking category.
table (Optional) Used in conjunction with the qos
-group keyword.
Indicates that the values set in a specified table map will be used to
set the MPLS EXP value.
table-map-name (Optional) Used in conjunction with the ta
ble keyword. Name of the
table map used to specify the MPLS EXP value. The name can be a
maximum of 64 alphanumeric characters.
