Juan,
Local acknowledgement is only available for DLSw+ Lite (LLC2)
and TCP. This is because they are the only two encapsulations available
that can guarantee transport. HDLC, SDLC, and IP are not reliable
transports, therefore cannot provide local acknowledgement to hosts
running DLSw+. If they did offer local ack, you run the possibility of
packets being dropped over the WAN while the originating host has
already gotten an acknowledgement for the packet.

Subject: DLSW & local llc2 ack
Hi all:
Anyone can clarify if dlsw provides local ack to llc2 session to all the
encapsulation types'
Or this is only for dlsw TCP encapsulated and Dlsw Lite? I've read this
doc

fibm_c/bcfpart2/bcfdlsw.htm#1002277
, but i'm not sure.
