This section describes adding a virtual switch to a domain, setting options for a virtual switch, and removing a virtual switch.
# ldm add-vsw [default-vlan-id=vlan-id] [pvid=[port-vlan-id]] [vid=vlan-id1,vlan-id2,...] [linkprop=phys-state] [mac-addr=num] [net-dev=device] [mode=sc] [mtu=size] [id=switch-id] vswitch-name ldom
default-vlan-id=vlan-id specifies the default virtual local area network (VLAN) to which a virtual switch and its associated virtual network devices belong to implicitly, in untagged mode. It serves as the default port VLAN id (pvid) of the virtual switch and virtual network devices. Without this option, the default value of this property is 1. Normally, you would not need to use this option. It is provided only as a way to change the default value of 1. See Using VLAN Tagging for more information.
pvid=port-vlan-id specifies the VLAN to which the virtual switch needs to be a member, in untagged mode. See Using VLAN Tagging for more information.
vid=vlan-id specifies one or more VLANs to which a virtual switch needs to be a member, in tagged mode. See Using VLAN Tagging for more information.
linkprop=phys-state specifies whether the virtual device reports its link status based on the underlying physical network device. When linkprop=phys-state is specified on the command line, the virtual device link status reflects the physical link state. By default, the virtual device link status does not reflect the physical link state.
Specify this option to use link-based IPMP. See Using Link-Based IPMP in Logical Domains Virtual Networking.
mac-addr=num is the MAC address to be used by this switch. The number must be in standard octet notation; for example, 80:00:33:55:22:66. If you do not specify a MAC address, the switch is automatically assigned an address from the range of public MAC addresses allocated to the Logical Domains Manager. See Assigning MAC Addresses Automatically or Manually for more information.
net-dev=device is the path to the network device over which this switch operates.
mode=sc enables virtual networking support for prioritized processing of Oracle Solaris Cluster heartbeat packets in a Logical Domains environment. Applications like Oracle Solaris Cluster need to ensure that high priority heartbeat packets are not dropped by congested virtual network and switch devices. This option prioritizes Oracle Solaris Cluster heartbeat frames and ensures that they are transferred in a reliable manner.
You must set this option when running Oracle Solaris Cluster in a Logical Domains environment and using guest domains as Oracle Solaris Cluster nodes. Do not set this option when you are not running Oracle Solaris Cluster software in guest domains, because you could impact virtual network performance.
mtu=size specifies the maximum transmission unit (MTU) of a virtual switch device. Valid values are in the range of 1500-16000.
id=switch-id is the ID of a new virtual switch device. By default, ID values are generated automatically, so set this property if you need to match an existing device name in the OS. See Virtual Device Identifier and Network Interface Name.
vswitch-name is the unique name of the switch that is to be exported as a service. Clients (network) can attach to this service.
ldom specifies the logical domain in which to add a virtual switch.
# ldm set-vsw [pvid=[port-vlan-id]] [vid=[vlan-id1,vlan-id2,...]] [mac-addr=num] [linkprop=[phys-state]] [net-dev=[device]] [mode=[sc]] [mtu=[size]] vswitch-name
mode= (left blank) stops special processing of Oracle Solaris Cluster heartbeat packets.
Otherwise, the command arguments are the same as described in Add a Virtual Switch.
# ldm rm-vsw [-f] vswitch-name
-f attempts to force the removal of a virtual switch. The removal might fail.
vswitch-name is the name of the switch that is to be removed as a service.
