Dscp Command (Frame Relay Vc-Bundle-Member) - Cisco 10000 Series Configuration Manual

Frame Relay PVC Selection
If you configure a PVC with the bump explicit command, you can specify the service level to which
traffic is bumped when that PVC goes down, and the traffic is directed to a PVC mapped with that level.
If the PVC that picks up and carries the traffic goes down, the traffic is subject to the bumping rules for
that PVC. You can specify only one service level for bumping.
The PVC accepts bumped traffic by default. If the PVC has been previously configured to reject bumped
traffic, you must use the bump traffic command to return the PVC to its default condition.
To configure a discrete PVC to reject bumped traffic when the traffic is directed to it, use the no bump
traffic command.
When no alternative PVC can be found to handle bumped traffic, even when there are no packets of that
Note
traffic type present, the bundle is declared down. In the case where default (implicit) bumping is used
for all PVCs, the PVC that is handling the lowest service level can be configured to bump explicitly to
a PVC handling a higher service level.

Specifies the DSCP level or levels for this Frame Relay PVC bundle
member. Valid values are from 0 to 63.
You can configure a PVC bundle member with a single DSCP level (9),
multiple individual DSCP levels (25,35,45), a range of DSCP levels
(25-35), multiple ranges of DSCP levels (25-35,45-55), or a combination of
individual levels and level ranges (10,20,25-35,40,45-55,60).
Note This command is available when the PVC bundle match type is set
to dscp. By default, the PVC members are configured to reject
bumping when the match-type is dscp.
Specifies that this Frame Relay PVC bundle member handles all of the
remaining DSCP levels that are not explicitly configured on any other
bundle members.
