3550 wccp road-map

[lunestadr]

Hi,

does anybody know if there is scheduled any enhancement to WCCP function on Catalyst3550 switches in upcoming sw releases?

I would like to have GRE redirection. These are the limitations I hope will be rectified:

Catalyst 3550 implementation of WCCP allows only Layer 2 redirection,

and not generic routing encapsulation (GRE). In addition, only TCP

port 80 may be redirected.

The connection of multiple Catalyst 3550 switches to multiple cache engines is not supported.

GRE redirection may not be supported because the layer 2 redirection is considered to be more efficient. The Web Content Communication Protocol (WCCP) Layer 2 (L2) Policy Feature Card (PFC) redirection feature allows Cisco Content Engines to perform a L2/MAC address rewrite redirection method when directly connected to compatible Cisco switches. The redirection processing is accelerated in the switching hardware, which makes this method more efficient than Layer 3 (L3) redirection with Generic Routing Encapsulation (GRE). L2 redirection takes place on the switch, and is not visible to the Multilayer Switch Feature Card (MSFC). The WCCP L2 PFC redirection feature requires no configuration on the MSFC. For more information read the following document.

Hi,

I'm aware of that the L2 redirection is more efficient. However, if you need to set up a redundant solution with two 3550 with HSRP, then the direct L2 connection poses problems.
