covergence in RSTP

Hi Experts ,

I know RSTP is mush faster than legacy STP or PVST because of its alternate
,,,back ports & a different algorithm to achive faster convergence in the
interswitch links & uplinks.

But I am little confused about its behaviour for edge ports i.e access
ports.

Yesterday I have done some tests ,,,.Observation is without enablings
portfast on acess ports ,if I am doing shut/noshut on that accessport
interface. convergence is slow and I am getting 10 packet drops b/w the
pings.

But with portfast enabled , convergence is faster and my gettig 2-3 packet
drop.

So, the question is if portfast is still required in RSTP ,then how will we
utilize its use in non-cisco environment .since portfast is cisco
propriteiry.....

Thanks,
Shekhar
