Frame Relay PVC Selection
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.)

Configuration Mode
Frame Relay VC-bundle-member configuration
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.
explicit
level
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.
implicit
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.
traffic
Specifies that the PVC accepts bumped traffic (the default condition). The
no
form stipulates that the PVC does not accept any bumped traffic.
