Feature Information for WCCP
Feature Information
The WCCP Closed Services feature
permits WCCP services to be
configured so that WCCP always
intercepts traffic for such services
but, if no WCCP client (such as a
content engine) has registered to
receive this traffic, packets are
discarded.
This behavior supports
Application-Oriented Network
Services (AONS) applications,
which require traffic to be
transparently intercepted using
WCCP but do not want the packets
to be forwarded to their destination
if the WCCP client is unavailable
to perform its processing. (This is
contrary to the traditional use of
WCCP to assist caches where the
absence of a cache does not change
the behavior as observed by the
user.)
The ip wccp command was
modified by this feature.
The WCCP Increased Services
feature increases the number of
services supported by WCCP to a
maximum of 256 across all VRFs.
The following commands were
modified by this feature: ip wccp,
ip wccp check services all, ip
wccp outbound-acl-check, show
ip wccp.
