Hi all, Does anyone know whether there is any notable performance difference with WCCPv2 using L2 redirect vs GRE as a packet forwarding method on 7200s? (NPE-400, NPE-G1, NPE-G2)?
WCCPv2 is a heavy user of processor cycles on our 7200s so I'm looking at ways to reduce the impact without performing major heart surgery. Currently we use GRE but our WCCP-speaking systems (cisco WAAS) are L2 adjacent so L2 redirect is a feasible option. I'm not familiar enough with the guts of CEF to know whether this is likely to make a big difference, but I guess there has to be less work in re-writing a MAC header than completely encapsulating a packet. cheers, Dale _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
