Usage Guidelines for the exp Command
Assignment of MPLS EXP levels to Frame Relay PVC bundle members allows you to create
differentiated service because you can distribute the levels over the various PVC bundle members. You
can map a single level or a range of levels to each discrete PVC in the bundle, thereby enabling PVCs in
the bundle to carry packets marked with different levels. Use the exp other command to indicate that a
PVC can carry traffic marked with EXP levels not specifically configured for other PVCs. Only one PVC
in the bundle can be configured using the exp other command.
All MPLS EXP levels must be accounted for in the PVC bundle configuration, or the bundle does not
come up. Note, however, that a PVC may be a bundle member but have no MPLS EXP level associated
with it. As long as all valid MPLS EXP levels are handled by other PVCs in the bundle, the bundle can
come up, but the PVC that has no MPLS EXP level configured does not participate in it.
The exp command is available only when tag-switching is configured on the interface with the
tag-switching ip command.
You can overwrite the EXP level configuration on a PVC by re-entering the exp command with a new
value.
The MPLS experimental bits are a bit-by-bit copy of the IP precedence bits. When Frame Relay PVC
bundles are configured for IP precedence and tag-switching is enabled, the precedence command is
replaced by the exp command. When tag-switching is disabled, the exp command is replaced by the
precedence command.
