Here is the web site that was referenced below. I got in so I
thought I would bring it into the topic for others if they couldn't
get to it.
Here are some pointers which everyone who had tried and failed to
configure including me are these... i also over looked and anyone who
have posted before with tested result they also.
1- When configuring RSAP and LSAP dont use ODD # like 1,3,5,7... use
2,4,6
2- In scenrio 1 i used simple bridging and there is nothing to do
with bit-swapping
3- In scenrio 2 i used bridging b/w TR and ether so i needed
bit-swap. BUT REMEMBER THAT BITSWAP COMMAND IS FOR LAYER 3.... YES
LAYER THREE. It will not benefit in this SNA enviroment so when
giving RMACs i bit-swapped there... from 7<->e and 4<->2
4- In scenerio 3 i used dlsw+ between Ra and Rb and bridge on there
ethernet.Now REMEMBER
DLSW ALWAYS USED MAC-ADDRESS FORMAT LIKE TOKEN-RING THAT IS
CONNONICAL. So there are ethernets and when i use RMAC without bit
swap then it will not work as DLSW RULZ. So i bitswapped and WOW it
works... In the archieves they have tested it so that they always
have TR on ends so it works but it will not work if ether.
5- DLSW will not preserve VLAN property... bridge do. In my scenrio 1
and 2
when i do diff vlan i dont work as i was working on one 5000 switch
so
that was the only way to seperate, when i use direct cross-overs it
works and in DLSW both ethernets are from different VLANS and are
working nicely as the DLSW CIRCUIT is showing.
for ur convinence i have made BATCH commands just built the scenerio
as under and copy and paste it to console and u will know everything
in a min.
