mpls experimental
To configure Multiprotocol Label Switching (MPLS) experimental (EXP) levels for a virtual circuit
(VC) class that can be assigned to a VC bundle and thus applied to all VC members of that bundle, use
the mpls experimental command in VC-class configuration mode. To remove the MPLS EXP levels
from the VC class, use the no form of this command.
To configure the MPLS EXP levels for a VC member of a bundle, use the mpls exper
imental command
in bundle-vc configuration mode. To remove the MPLS EXP levels from the VC, use the no form of this
command.
mpls experimental [ot

no mpls experimental
Syntax Description
Defaults Defaults to othe
r, that is, any MPLS EXP levels in the range from 0 to 7 that are not explicitly
configured.
Command Modes VC-class configuration for a VC class (config-vc-class)
Bundle-vc configuration for ATM VC bundle members (config-if-atm-member)
Command History
Usage Guidelines Assignment of MPLS EXP levels to VC bundle members allows you to create differentiated service
be
cause you can distribute the MPLS EXP levels over the different VC bundle members. You can map
a single level or a range of levels to each discrete VC in the bundle, thereby enabling VCs in the bundle
to carry packets marked with different levels. Alternatively, you can configure a VC with the mpls
experimental other command to indicate that it can carry traffic marked with levels not specifically
configured for it. Only one VC in the bundle can be configured with the mpls experimental other
command to carry all levels not specified. This VC is considered the default one.
To use this command in VC-class configuration mode, enter the vc
-class atm global configuration
command before you enter this command. This command has no effect if the VC class that contains the
command is attached to a standalone VC, that is, if the VC is not a bundle member.
other (Optional) Specifies any MPLS EXP levels in the range from 0 to 7 that are
n
ot explicitly configured. This is the default.
range (Optional) A single MPLS EXP level specified as a number from 0 to 7, or
a ra
nge of levels, specified as a hyphenated range.
