Oracle VMs and VLANs

UNIX Solaris

I've been given an IP address to assign to an ldom that is in a different subnet than the host, and I am looking for assistance in getting it online. I believe I need "VLAN tagging" as found in this link, but I do not understand all of the terminology.

My host machine is on subnet 10.25.112.x, and I have ldoms on the same subnet that are online and working properly. My new ldom has an IP address on the subnet 10.26.63.x.

host

root@sun10:/# ldm list-services
VSW
    NAME             LDOM             MAC               NET-DEV   ID   DEVICE     LINKPROP   DEFAULT-VLAN-ID PVID VID                  MTU   MODE   INTER-VNET-LINK
    primary-vsw0     primary          00:14:4f:fb:e8:b5 igb0      0    switch@0              1               1                         1500         on

LDOM same subnet

[root@vm-s1: /]# netstat -rn

LDOM different subnet

I don't fully understand the example they give in this link. In my situation is the 112 subnet the untagged VLAN?

I believe your switch port will have to be configured as trunk (the real switch port to which primary vsw is connected via igb0)

Before the change, be sure to inspect other ldom network configurations using the same vsw and actual switch port setup (trunk).

Then you change your vsw


ldm set-vsw pvid=1 vid=63 primary-vsw0 # assuming vlan id for 10.0.63.x is 63..

If you need more then 63, you will add them with comma [/icode]...vid=63,220,75[/icode]

Then you add your vnet device with additional vid=63 option per ldom (or multiple vids)

Configure route and ip address on ldom host for the new interface (as you did).
