hello, I have a problem when configuring the network at the LDOM level, on a SPARC-Enterprise-T5120 machine
The network goes through VLAN 503 (level, network tagget)
And I need to give network to the guest domain: madarrwebsol10
I hope someone can bring some light ....
Excuse my English ...

This way, tagging will be done by hypervisor vnet/vsw, not inside guest domain.
Guest domain will be in VLAN 503 exclusively.
Good practice would be to aggregate all four network ports into one aggr0 then use that for as net-dev.
You will get redundancy in case of failure, as well as combined bandwidth of 4 network ports.
Also, on that aggregated interface specify as many VLAN ids that are used in your environment when creating VSW.
The switch network ports should be configured as trunk.
You only need VLAN (dladm create-vlan) interface for the hypervisor IP address.
I would recommend using seperate VLAN id for hypervisor ip address (security wise).
Creating VSW with name of virtual machine is not proper naming.
Human is for instance : lab-vsw0, prod0-vsw or similar descriptive name.
You will use that virtual switch for other machines as well, so naming it after one ldom is not so straightforward.
Be careful about naming in Oracle VM server hypervisor, it will allow you to name anything you like as you like it.
When you have a lot of machines, naming policy will save you extra investigation what is mapped where (disks, vsw to ldom etc.)
I have a Sun T4-1 running Solaris 11.4 with a static IP 192.168.0.183. On this machine is a Solaris 10 LDOM with a static IP of 192.168.0.78. The other day I had to stop the LDOM to do a memory reconfigure. When I rebooted it I got an error that the IP 192.168.0.78 was already in use and so... (4 Replies)

Hi,
Our existing environment is having primary domain and 3 guest domains are running over it. See the attached image.
Now we want to add a new primary virtual switch and move LDOM3 to be connected with new primary switch.
So, I am not sure how to achieve this because. If I remove the... (7 Replies)
I have an Oracle VM set up with 1 virtual disk. I am trying to add 2 new disks to it. I was able to successfully add 1 (it appears when I run "format" in the VM) but when I add the second and third disks they do not appear in my VM.

Hi,
I have a question on web servers and network switches.
Why a network switch should support certificate management, that means generating public and private keys... installing a certificate etcetra.
