Host-Managed VLAN Configuration
With this method, the user only adds a vNIC to the server on the chassis and
manages its VLAN configuration from the server using the native operating system
tools. To support host-managed VLANs, the vNIC must be created in trunk mode.
For information about trunk mode, see “Mode” on page 122.
This serves as an acknowledgement to the vNIC configuration software on the
chassis that the VLANs are configured from the host side and the Oracle Fabric
Interconnect should honor VLAN configuration requests coming from the host.
The Oracle Fabric Interconnect can thus allow tagged packets to go across this vNIC
which otherwise would get dropped when the vNIC is in access mode of operation.
The Oracle Fabric Interconnect-maintained vNIC configuration information is
updated as VLANs are configured on the host. This information can be displayed
using the show vlans command.
All host-managed VLANs are shown as hostManaged in the Type column of the
show vlans output.
The output of the show vlans command contains two address fields: admin-addr
and oper-addr. The admin-addr field is the VLAN’s IP address that is configured
on the Oracle Fabric Interconnect, and the oper-addr field is the VLAN’s IP
address configured on the host. If a VLAN is host-managed, the admin-addr shows
0.0.0.0.
Chassis-Managed VLAN Configuration
VLANs are configured from the Oracle Fabric Interconnect through the add vlan
and set vlan command sets. Currently only one chassis-managed VLAN can be
configured per vNIC.
