RE: Additional IOA connection

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

We have two Ethernet line .1 & .2.  Our router has to routes to our VIP
which is not in the same subnet.  The router has given .1 a lower metric
than .2.  Each line is plugged into a different switch.  Basically inbound
traffic is sent via .1 and outbound go via .2.  That is IBM's load
balancing.   We only use about .1 % of the bandwidth on each Ethernet line
so I cannot say how it would work on a heavy environment.  Also if you are
using dumb hubs, upgrade to a switches.  Ones capable of full duplex.  Are
you running your adapter at 100M Full Duplex?  Can make a world of
difference.

Subject: Additional IOA connection


We have been experiencing a tremendous amount of telnet sessions dropping
and tcp/ip connections breaking to our NT servers since we've gone live
with V4R5 and migrated to an 830 2-way.  We have approximately 350
interactive users, 80 tcpip connections used by Datamirror's Transformation
server product, and 30 ODBC users.  Rochester has looked and looked at our
system and all they can say is our problem is 'network congestion'.  One
suggestion has been to add another IOA and define another ethline.  I'd
like to try this but I can't find any GOOD examples in the Information
Center or the books on CD for this scenario.  Could anyone who has done
this please share HOW they did it?  I've read the short write-up on
duplicate route-based load balancing and load balancing with virtual IP,
but I don't see HOW I can 'tell' my IP traffic which line to use.  In other
words, I want to restrict my telnet traffic to one ethline and all other ip
traffic to the other ethline.  Am I dreaming?  Can this be done?  Many
thanks for your help.
