One of the better books for CIP (Channel Interface Processor) configuration
is ISBN #1578700833, _Internetworking_SNA_With_Cisco_solutions_. This book
was written by George and Nancy Sackett, who also wrote some IBM
documentation a while back, I think.

Since this device is not on the equipment list for the R&S exam, I wouldn't
spend much time on it - However, it is a valuable bit of knowledge to have
with all the IBM mainframe shops out there.

FWIW, The CIP connects to a mainframe via an ESCON (Enterprise System
Connection - big fast fiber) or parallel (slower copper) connection. CIPs
can support up to 2 connections. From there, you can configure the CIP to
do APPN (not too familiar with that one), or LLC connections via a virtual
token ring and SRB, so the CIP can do what a 3745 (front-end processor)
does. Additionally, you can run this LLC traffic into DLSw+, and terminate
the other end on a serial custer controller (3174R, I think), or other
network. CIPs also support TN3270, so they can act as your TN3270 server.

On a mainframe running as a sysplex, with multiple LPARs (conceptually like
the mainframe version of a VLAN), you can use a single channel connection to
establish connectivity to all LPARs (Like a channel can provide routing for
multiple VLANs.)

This is probably more information than you ever wanted to know, but I think
it's interesting and worth looking over once - but this is coming from the
guy who configured VINES, Apollo, and XNS just for fun before lab...

If anyone would like some more information, drop me a line, and I'll drag
out the book I mentioned above and see what I can come up with....

steven,

I agree. One of the books I am reading, Network Design and Case Studies,
devotes an entire chapter on CIP. I am familar with the basic concept of
CIP, but have never configured it. I just didn't want to waste time on
something that would be impossible to be in the lab (impossible because
its not on the equipment list)
