IOS SLB is old feature that was deprecated some time ago in
the IOS. The natural migration path was Cisco CSM, then ACE
service card, but then it was itself EoSed.

Right now it’s either F5 or Citrix for large-scale load
balancing. Or our beloved L3/L4 which you mentioned in 
previous post.

While Sup720 may still support it, 15.1Y and newer versions for
Sup2T don’t. This means: some commands may be there in the parser,
trick you in entering them, and then kill you with performance,
bugs, or simply do not work at all, which sometimes is blessing.
