List,
We have zLinux (SLES 10&11) and z/VSE (v. 4.2.2) guests under one z/VM instance
in z10, and the
guests should be connected to vlan 46 or 58.
VSEs are vlan unaware and support only layer 3.
zLinuxes are configured as vlan aware (and of course for layer 2).
Two vswitches are defined, vsw1 for zLinuxes and vsw2 for VSEs:
Define vswitch vsw1 rdev 200.p1 250.p1 ETHERNET
Define vswitch vsw2 rdev 204.p1 254.p1 IP vlan 58 porttype access nogvrp
One port of two OSA cards (OSA-Express3 dual-port cards) are connected to trunk
ports of physical
switches 1 and 2.
So, actually, all the guests are connected to the external LAN via one OSA port
and one physical switch.
VSESIMUL connects to vlan 58, VSESYS to vlan 46 and zlnx002 to vlan 58:
SET VSWITCH VSW2 GRANT VSESIMUL PORTTYPE ACCESS VLAN 58
SET VSWITCH VSW2 GRANT VSESYS PORTTYPE ACCESS VLAN 46
SET VSWITCH VSW1 GRANT ZLNX002
zlnx002:~ # ifconfig vlan58
vlan58 Link encap:Ethernet HWaddr 02:01:01:00:00:05

These connections work:
- VSESIMUL <-> VSESYS
- VSESIMUL <-> zlnx002
but this fails:
- VSESYS <-> zlnx002
So what might be wrong in our setup so that vlan 58 hosts connected to vsw1 and
vlan 46 hosts
connected to vsw2 cannot talk to each other?
I have tried to figure this out, but actually I don't know in general which
parts are involved in
VSESYS <-> zlnx002 connection out of the "maximum path"
VSESYS <-> VSW2 <-> OSA adapter (rdev 254-256) <-> physical switch <-> OSA
adapter (rdev 250-252)
<-> VSW1 <-> zlnx002
being a network amateur to be honest...
I attach the full vswitch status (sorry for long output).
Thanks in advance for any help.
