Don't think you can do this I'm afraid as it is in the nature of the ASICs imho. Apparently there may be a resurgence of cut-through switching through enhanced ASICs but I believe it's only store-and-forward at present.

Hello Friend,

If you want to use cut-through mode between interfaces within the same bridge group, use the cut-through command in interface configuration mode. To return to store-and-forward mode just use no form of this command.

Syntax:

cut-through [receive | transmit]

no cut-through

receive - (Optional) Selects cut-through switching technology on received data

transmit - (Optional) Selects cut-through switching technology on transmitted data

Example config:

SW(config)# interface fastethernet 3/0

SW(config-if)# bridge-group 10

SW(config-if)# cut-through

SW(config-if)# no shutdown

SW(config-if)# exit

SW(config)#

That's all!  Any other question? Hope will be helpful:)

Regards,

S.Vusal
