We are trying to move the IP connection on our Z/800 from a
Cisco CIP connection to an OSA Express GB ethernet connection.
Currently we have a single CLAW link from a CIP router into a Z/VM stack
All of the other TCP/IP stacks are being reached by routes
from Z/VM across real CTC (for LPARS), virtual CTC (within VM) or
IUCV links.
We are trying to eliminate point to point connections by moving to
a combination of OSA links to each LPAR, Hipersockets between
LPARS and Vswitches within LPARS.
We have set up a new test routing structure within the Z/800
that looks like this.
Single two port OSA Express GB ethernet adapter on CHPIDs 00 and 01.
Device addresss in IOCP for CHPID 00 are A000-A00e
Device addresss in IOCP for CHPID 01 are b000-b00e
The main TCP/IP stack in each LPAR has a direct link to the OSA on
CHPID 0.
The tcp/ip stacks in the LPARs are all linked across a
single HiperSocket (chpid EC)
The third LPAR also
contains a VSWITCH with two guest VM TCP/IP machines defined
with the statements shown at the end of this note.
Since we are testing without an external connection to the OSA,
we set up a route from one of the VSWITCH Lan guests to the Hipersockets
path to test connectivity from the virtual LAN to the other LPARS.
It appears that all paths are now functional. (at least reachable)
We are now ready to connect this configuration to a CISCO Catalyst 4006
switch and a Catalyst 6509 router.
The networking folks haven't worked with an OSA before and wanted
to know if there is documentattion describing the configuration
of the CISCO equipment to define the following connections:
1. Connect the three direct OSA links (137.216.4.10, 4.11 and 4.12)
to the external network.
2. Connect the virtual LAN to the external network
(Initially as VLAN unaware)
Any pointers for them would be appreciated.
