Nicolas/All, Thanks for you replies. I am now able to achieve what I wanted.
Doing 'snoop vlan' from the parent interface showed me VLAN ID and the packets. The part I was missing was 'dladm create-vlan' and the plumbing that interface. I was assuming that, since I created vnet using 'ldm add-vnet vid=xxx', plumbing vnet will be automatically using tagged packets.

We were able to ping the thus created VLAN interfaces, but we were not able to 'snoop' and VLAN tags in the packets. 'snoop vlan' is still not supported in S10. Next we tried with Nevada. Here the PPA (interface+vid*1000+instance) did not work at all (obviously). Inside the LDOM, we were able to create vnet0 instead of say vnet20000 (vid 20) in Solaris 10. Still, we were not able to see any VLAN tags in the packets between the LDOMs.In OpenSolaris the "PPA hack" support for configuring VLANs was removed, VLANs data-links are now created with dladm(1M) create-vlan.(pinged through the VLAN interface IP addresses, or did a 'telnet ip')Where are we going wrong? Are we wrong to assume that we can 'snoop' the VLAN tags in the packets that flows between two VLAN tagged network interfaces? Would using two different systems instead of using two LDOMS make any difference? Thanks a lot.LDOMs require you to assign the VLANs to the vnets when you create them using the ldm(1M) add-vnet command. Once you've done this you should see tagged traffic if you snoop the vnet "physical" data-link directly from your guest domain. Then you can create configure your VLANs with the "PPA hack" if you are running a S10 domain, or with dladm create-vlan if you are running an OpenSolaris domain.See also the "Using VLAN Tagging With Logical Domains Software" of the LDOM user guide on docs.sun.com, which has all the details.[email protected] can also be used for LDOM-specific questions.Nicolas.-SivaPS: I am not subscribed to this mailing list.
