Did you mean "deployable" or "deplorable" ;o)

Rubens,

A briefing we had 18 months or so ago basically said:

  * SXH - initial release, to be released shortly (hahaha) some 12.2(33) 
features, each "version" will have 12 months support

  * SXI - major release, to be released later (hohoho) most features, 
will have the "extended" 24 months support that some SXF releases had

Information is scanty (non-existent?) but I suspect something like the 
following happened:

  * Work starts on SXH *and* SXI more or less simultaneously

  * Problems start in SXH train e.g. they start to slip, finding VSS, 
sup720-10g and 6708/6716 linecard hardware support are harder

  * SXH train gets even later - cisco add more manpower making it later 
still - eventually gets released in a pretty shabby state

  * Meanwhile all this time SXI has been working on the "other" features 
and ironically since it's had a later deadline, has been going slower 
and is more on-track

I personally doubt we will see much more of SXH. We'll probably see an 
SXH4, since there are known crash bugs in SXH3a, but I'd be surprised to 
see anything beyond that.

I wonder if people are interested in coordinating their testing and 
pooling results?
