Which platforms support GRE in hardware

Is there a document which summarises the devices which support GRE in hardware and the limitations ?

Am i correct in thinking the entry evel for h/w based GRE is the SUP32 PISA ?

Is there no hardware support for GRE in the 4500, even with 10Gb Sup ?

All assistance very gratefully received.

Re: Which platforms support GRE in hardware

On 6k, Sups running in PFC-3B mode and up will support GRE in hardware. Use "show platform hardware pfc mode" to verify.

On 4500, the sup7E has the capabilities for hardware support, but I dont think the software has yet been released to support GRE in hardware.  Last I can find, the software release was aimed at post-launch, which I believe just came recently in August or so.

Any idea about how i can confirm:

1: the fact that the sup 7e will support GRE in hardware (before buying a couple)

2: the fact that the code WILL be released and when ?
