mpanlDlciLCoBumpPreference
mpanl Dlci L Co Bump Preference
This attribute specifies when bumping will occur during the route selection process. Bumping may occur when necessary or always. It will be necessary for a connection to bump if there is not enough resources for the connection to be established and these resources are occupied by a connection whose holdingPriority is lower (numerically higher) than the connection's setupPriority. A connection may also always bump in order to obtain the best route.
