According to the network folks the OSA card is plugged into a trunk port
and the native VLAN id is 147.
We are on z/VM 520 so as you say the default VLAN must be the same as the
native VLAN.
Thanks.

What release of VM on you on? In 5.3.0, we separated the default VLAN and
the native VLAN. Prior to 5.3.0, the default VLAN is the same as the
native VLAN. In this case, defining the VSWITCH to default to VLAN 147
means that 147 is the native VLAN (or untagged set). Most likely, the
OSA card is plugged into an access port on the physical switch and traffic
coming into the VSWITCH for 147 is not tagged. Once you change the
default on the VSWITCH that untagged traffic is associated with the new
default (which does not equal 147) and is then not delivered to the guest
(granted VLAN 147). A conversation with your networking folks is
probably in order. In most situations, we recommend that if you want to
use VLANs on your VSWITCH plug your OSA card into a trunk port on the
physical switch. Then define your VSWITCH to default to the native VLAN
id of the physical switch.

Another VSWITCH question
Thanks for the replies to my previous question.
Our network folks have configured their 6509 connection to our OSAs with 1
VLAN - 147.
If I define my VSWITCH with a default VLAN ID of 147 and then "grant
IPSTACK VLAN 147" - all is OK - I can PING etc.
However if I define the VSWITCH with a different VLAN ID I cannot PING
etc.
I assume that the switch will tag any packets coming from IPSTACK with
VLAN
147 so I should always be able to PING etc even if the default VLAN is not
147.
What's the problem here? Me?
Thanks.
