[tobymundy57]

Is packet manipulation, interconnection of distribution layer devices, access list filtering, redundancy between core devices only and high-speed backbone switching all responsibilities of the distribution layer?

"Is packet manipulation, interconnection of distribution layer devices, access list filtering, redundancy between core devices only and high-speed backbone switching all responsibilities of the distribution layer?"

(Generally, for all that, in a traditional 3 layer topology) no.

(@balaji.bandi provides a fine reference, which not only discusses "traditional" core, distribution and access, but many of the variations, too.)
