This MIB object configures switching mode configuration at switch level. The switching mode configuration done at switch level will be applied on all the ports in the system including stacking ports. When configured as StoreForward(2), the switch operates in a store-and-forward mode and the switch checks each frame for cyclic redundancy check (CRC) errors before forwarding them to the network. Each frame is stored until the entire frame has been received and checked. Because the switch waits for forwarding the frame until the entire frame has been received and checked, the switching speed in Store-Forward switching mode is slower than the switching speed in Cut-Through switching modes. When configured any of the cut-through modes, the switch operates in Cut-Through switching mode and start forwarding the frame as soon as the switch has read the destination details in the packet header. A switch in Cut-Through mode forwards the data before it has completedreceiving the entire frame. The switching speed in Cut-Through mode is faster than the switching speed in Store-Forward switching mode. Switching mode configuration: CutThroughSameSpeed(1) : Cut-through forwarding between same speed ports StoreForward(2) : Store and forward switching mode CutThroughSlowToFast(3): Cut-through forwarding between slower to faster speed ports. CutThroughFastToSlow(4): Cut-through forwarding between faster to slower speed ports. NOTE: Few platforms supports extended Cut-Through mode for ports with mismatched speeds.(eg. slow-to-fast, fast-to-slow). Platforms which doesn't support extended Cut-Through mode, Cut-Through same speed shall be considered as Cut-Through switching mode
