line. Scrambling may be applied at the cell level, at the frame level or at cell and frame level. The scrambling configuration can only be modified for a wan interface.

cell-in-receive-only applies only for a wan interface. In this case, the cells are descrambled when received, and are not scrambled when transmitted. cell-in-transmit-only can only be set for a wan interface. In this case, the cells are not descrambled when received, and are scrambled when transmitted.″

interfaceMaxBandwidth OBJECT-TYPE SYNTAX INTEGER

ACCESS read-write STATUS mandatory

DESCRIPTION

″For a SSI port: the maximum bandwidth usable on this port.

Out of this defined bandwidth: at most 85% are usable for the reserved bandwidth connections and at least 15% are usable for the non reserved bandwidth connections.

The interfaceMaxBandwidth must not exceed the physical bandwidth of this port: interfaceMediaSpeed. The minimum valid value to set for the interfaceMaxBandwidth is 60000 bps, which is the bandwidth requested to set a non-reserved bandwidth connection on this ssi link.

The interfaceMaxBandwidth must be equal on each side of an SSI link to avoid route computation deadlocks. The default value is equal to interfaceMediaSpeed.

For a port which is not a SSI port, the maximum bandwidth cannot be changed and remains equal to interfaceMediaSpeed.

The interfaceMaxBandwidth is given in bits per second. The interfaceMaxBandwidth can be modified only when the
