Usage Guidelines for the bump Command
If you configure implicit bumping, bumped traffic is sent to the PVC configured to handle the next lower
precedence level. When the original PVC that bumped the traffic comes back up, the traffic that it is
configured to carry is restored to it. If no other positive forms of the
bump
command are configured, the
bump implicit
command takes effect.
If you configure a PVC with the
bump explicit
command, you can specify the precedence level or MPLS
EXP level to which traffic is bumped when that PVC goes down, and the traffic is directed to a PVC
mapped with that precedence or MPLS EXP 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 precedence 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.
