Chapter 7 Virtual LANs (VLANs) 119
These properties collectively define rules by which the Oracle Fabric Interconnect
operates and handles VLAN tagged and untagged frames.
When configuring a VLAN, you must set VLAN properties on the Ethernet port
before any vNICs are assigned to it.
If you are changing the VLAN settings of an Ethernet port that already has
configured vNICs bound to it, you must remove all the vNICs associated with the
terminating port before changing the settings. Otherwise, set commands fail. VLAN
properties are configured on an Ethernet port using the set ethernet-port
command. For additional information about the VLAN properties of an Ethernet
port, see “Ethernet Port” on page 120.
Be aware that the configuration of VLAN properties must match on both ends of the
physical connection. Any mismatch in configuration results in improper handling of
data traffic.
After the VLAN properties of the Ethernet port are configured, vNICs can be created
and terminated on the port with appropriate VLAN properties.
A vNIC’s VLAN properties are configured depending on the type of configuration
method chosen, either host managed or chassis managed.
Note – A VLAN can be configured for a Link Aggregation Group (LAG) as well as
an Ethernet port. Any VLAN properties configured to the LAG are set on all
Ethernet ports in the LAG group, the same as a single Ethernet port in a VLAN.
There are no special commands or configuration steps for configuring VLANs on a
LAG.
Host-Managed VLANs
Host-managed VLANs are configured and managed from the host server using the
native operating system tools. This method can help administrators by allowing
them to use traditional administrative tools and methods to configure the vNIC
accordingly. For more information about configuring host-managed VLANs, see
“Host-Managed VLAN Configuration” on page 124.
Chassis-Managed VLANs
Chassis-managed VLANs are configured and managed from the XgOS CLI. For
more information about configuring chassis-managed VLANs, see
“Chassis-Managed VLAN Configuration” on page 124.
