issSwitchModeType

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
