I have a default VSWITCH defined and connected to my OSA express card. z/VM 5.2.
The following userids are coupled to the VSWITCH. Q vswitch detail output at
end of note.
TCPIP (142.214.154.50)
LINUX02 (142.214.154.42) (SLES10)
SLES10 (142.214.154.51) (SLES10)
LINUX04 (142.214.154.44) (SELS10)
LINWAS (142.214.154.45) (SLES9)
Gateway IP is 142.214.154.1
Mask is 255.255.255.128
>From LINUX04 I can ping TCPIP but not LINUX02 or SLES10
>From TCPIP I can ping all Linux systems
>From LAN (142.214.195.65-different subnet) I can ping all.
Problem: I can not ping from any of the linux guest to any other.
My route on linux is a follows:
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
142.214.154.0 * 255.255.255.128 U 0 0 0 eth0
link-local * 255.255.0.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default 142.214.154.1 0.0.0.0 UG 0 0 0
eth0LinuxSLES10Controller:~ #
My IFCONFIG is
ifconfig

I cant see why this shouldnt work
Now heres the scary part: I changed the routes file on LINUX02 to
Default 142.214.154.1 255.255.255.128
and recycled the network card. I was then able to ping LINUX04 and I think it
worked because it went out to the gateway. I was not able to ping LINUX02 from
a different subnet on the LAN so I changed back the route default to 0.0.0.0.
By doing this both LINUX04 and LINUX02 can ping each other but I still cannot
ping SLES10. Did VSWITCH record/map the IP address to the MAC address or
something? Do I need a fix?
Any comments/suggested are greatly appreciated.
Thanks Hans Rempel
