Configuring WCCP
Feature Information
The WCCP Layer 2
Redirection/Forwarding feature
allows directly connected Cisco
content engines to use Layer 2
redirection, which is more efficient
than Layer 3 redirection via GRE
encapsulation. You can configure
a directly connected Cache Engine
to negotiate use of the WCCP
Layer 2 Redirection/Forwarding
feature. The WCCP Layer 2
Redirection/Forwarding feature
requires no configuration on the
router or switch.
There are no new or modified
commands associated with this
feature.
The WCCP L2 Return feature
allows content engines to return
packets to WCCP routers directly
connected at Layer 2 by swapping
the source and destination MAC
addresses rather than tunneling
packets back to the router inside a
Layer 3 GRE tunnel.
There are no new or modified
commands associated with this
feature.
The WCCP Mask Assignment
feature introduces support for
ACNS/WAAS devices using mask
assignment as a cache engine
assignment method.
There are no new or modified
commands associated with this
feature.
