From the command reference for the "bandwidth" command:
"Besides specifying the amount of bandwidth in kbps, you can assign
bandwidth as a percentage of the available bandwidth. During periods of
congestion, the classes are serviced in proportion to their configured
bandwidth percentages. Available bandwidth is equal to the interface
bandwidth minus the sum of all bandwidths reserved by Resource Reservation
Protocol (RSVP), IP RTP Priority, and low latency queueing (LLQ). "
