Problem: So I was working on implementing WCCP redirection for networks to get TCP accelerated between two data centers and I ran into a problem. The problem was that subnets behind the core switches were not getting WCCP redirected into the WAAS units. So I wonder why? It’s matching the redirect-list ACL and shows up [...]
WCCPv1: ———————— 1. Only single router can participate in a cluster of WCCP-capable devices 2. Intercepts and redirects HTTP and HTTPS 3. Does not allow load balancing WCCPv2: ———————— 1. Supports multiple routers can redirect to clusters and devices, allows for load balancing. 2. Support for non HTTP and HTTPS protocols such as other TCP [...]
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 [...]
