Steve, I discussed this in the VSWITCH and VLAN Redpaper which you can find
at:

  http://www.redbooks.ibm.com/abstracts/redp3719.html

I'd be keen to hear what you think of it, so please let me know or use the
feedback e-mail address on the Redbooks site.

Cheers,
Vic Cross


An interesting finding and a question; you use the term "must" with respect
to configuring the PORTNAME option of DEFINE VSWITCH when it appears to be
optional parameter. I might be taking this out of context as the statements
made only refer to the placement of the PORTNAME parameter ("PORTNAME must
be the last parameter") but it reads like this parameter is not optional. I
find that it really isn't necessary to address the port name when defining a
functional switch but it might be prudent to do so. Is there any situation
that you can think of where not addressing the OSA port name in the switch
definition might trip someone up?

Also, when configuring the TCPIP service machines to autolog, I find it
helpful to put the MODIFY VSWITCH GRANT statements in SYSTEM CONFIG instead
of using CP SET VSWITCH GRANT from the profile of AUTOLOG1. This saved me a
lot of typing yesterday when AUTOLOG1 didn't start forcing me to manually
start the Controller service machines (still researching why AUTOLOG1 didn't
start). You do make mention of configuring access to the switch through CP
SET VSWITCH but not through MODIFY. Do you see a disadvantage to making use
of MODIFY from SYSTEM CONFIG in this manner?

The paper is well organized, well written and proved to be very helpful to
my configuration efforts. I found the general discussion on VLANs and how CP
implements them informative and complete. This is very good work.

Thanks Vic
