Is the native VLAN of the switch really 485? When the guest VLAN is the same
as the specified native VLAN, the frame is sent untagged. That will cause the
switch to apply the port default VLAN, which is the native VLAN unless it has
been overridden.
In most cases, the native VLAN is 1.

Subject: [IBMVM] Create z/VM Layer 2 VLAN / VSwitch
Hi,
i am not a networking expert, but need to build a layer 2 vlan in z/VM
5.4. Linux is Suse SLES 11 SP1.
I was told to use layer 2 for VLAN 485 so i used these commands to create
vswitch / vlan
DEFINE VSWITCH VMT1VSW0 RDEV E606 E706 CONTROLLER * ETHERNET VLAN 485
native 485
DEFINE LAN VMT1LN01 OWNERID SYSTEM TYPE QDIO ETHERNET MAXCONN INFINITE
UNRESTRICTED ACCOUNTING OFF
the Linux guest nic is defined in the directory
NICDEF 9000 TYPE QDIO DEVICES 3 LAN SYSTEM VMT1LN01 MACID E32200
So after defining / starting everything my system looks like this:
q vmlan

i also performed the proper RACF definitions for vlan 0485 (UACC(UPDATE))
+ refresh
nic defined in the linux guest using yast with proper ip address.
but i can not get any ping to work from / to the linux system. i know this
is also related to the routes which are not changed at the moment, but i
should be able to see a ping comming in using tcpdump, or not ?!?
any hint what is wrong in my configuraiton?!?
