bump Command (Frame Relay VC-bundle-member)

To configure the bumping rules for a Frame Relay permanent virtual circuit (PVC) bundle member, use
the bump command in Frame Relay VC-bundle-member configuration mode.To specify that the PVC
bundle member does not accept any bumped traffic, use the no bump traffic command. (The no bump
explicit and no bump implicit commands have no effect.)

Usage Guidelines for the bump Command
Use the bump command to configure bumping rules for a discrete PVC bundle member. To change the
configured bumping rules for a PVC bundle member, override the current configuration with a new
bump command entry.
To return to the default condition of implicit bumping, use the bump implicit command.
If you configure implicit bumping, bumped traffic is sent to the PVC configured to handle the next lower
service level. When the original PVC that bumped the traffic comes back up, it resumes transmission of
the configured service level. When the bump explicit command is not configured, the bump implicit
command takes effect by default; however, the bump implicit command does not appear in the output
of the show running-config and show startup-config commands.

Specifies the precedence, MPLS experimental (EXP), or differentiated
services code point (DSCP) level to which traffic on a PVC is bumped when
the PVC goes down. For PVC bundles that use precedence or MPLS EXP
mapping, valid values for the level argument are from 0 to 7. For PVC
bundles that use DSCP mapping, valid values are from 0 to 63.
Applies the implicit bumping rule, which is the default, to a single PVC
bundle member. The implicit bumping rule stipulates that bumped traffic is
to be carried by a PVC that has the lower precedence level.
Specifies that the PVC accepts bumped traffic (the default condition). The
no form stipulates that the PVC does not accept any bumped traffic.
