Frame Relay VC-bundle-member configuration
Usage Guidelines for the dscp Command
Assignment of DSCP levels to PVC bundle members allows you to create differentiated service because
you can distribute the DSCP levels over the various PVC bundle members. You can map a single DSCP
level or range of levels to each discrete PVC in the bundle, thereby enabling PVCs in the bundle to carry
packets marked with different DSCP levels. Use the dscp other command to configure a PVC to carry
traffic marked with DSCP levels not specifically configured on other PVCs. Only one PVC in the bundle
can be configured with the dscp other command.
This command is available only when the match type for the PVC bundle is set to dscp using the match
dscp command in Frame Relay VC-bundle configuration mode.
You can overwrite the DSCP level configuration on a PVC by re-entering the dscp command with a new
level value.
There is no default value for this command.
When the PVC bundle is set to dscp using the match dscp command, all PVCs in the bundle are reset to
remove any existing DSCP values. If one or more DSCP values are not specifically configured, the
bundle does not come up.
Note, however, that a PVC may exist in a bundle but have no DSCP value associated with it. As long as
all valid DSCP values are handled by one or more of the other PVCs in the bundle, the bundle can come
up, but the PVC that has no DSCP value configured does not participate in it.
A DSCP level can be configured on one PVC-bundle member per bundle. If you configure the same
DSCP level on more than one PVC within a bundle, the following message appears on the console:

exp Command

To configure Multiprotocol Label Switching (MPLS) experimental (EXP) levels for a Frame Relay
permanent virtual circuit (PVC) bundle member, use the exp command in Frame Relay
VC-bundle-member configuration mode. To remove the EXP level configuration from the PVC, use the
no form of the command.
exp {level | other}
no exp
Syntax Description
level
other
OL-7433-09
Specifies the MPLS EXP level or levels for a Frame Relay PVC bundle
member. Valid values are from 0 to 7. You can configure a PVC bundle
member with a single MPLS EXP level (0), multiple individual MPLS EXP
levels (0,2,3), a range of MPLS EXP levels (0-2), multiple ranges of MPLS
EXP levels (0-2,4-5), or a combination of individual levels and level ranges
(0,1,2-4,7).
Specifies that the Frame Relay PVC bundle member handles all of the
remaining MPLS EXP levels that are not explicitly configured on any other
bundle member PVCs.
