This option allows 6500/7600 to use hardware acceleration for WCCP packets in Layer 2. This method in theory allows you to utilize up to 3Gbps of traffic on a PFC2 card, perhaps even more with a PFC3B.

The device (eg: WAE or ACNS) needs to have layer 2 adjacency with the 6500 switch in order to take advantage of hardware redirection. If you do not have layer 2 direct adjacency, then most likely you will have to use the GRE tunneling method of WCCP to redirect transparently.
