Information About WCCPv2
WCCPv2 specifies interactions between one or more Cisco NX-OS routers and one or more cache
engines. WCCPv2 transparently redirects selected types of traffic through a group of routers. The
selected traffic is redirected to a group of cache engines to optimize resource usage and lower response
times.
Cisco NX-OS does not support WCCPv1.
