@@ -5,31 +5,43 @@ The ``nics`` table and the ``confignetwork`` script can be used to automatically
To use ``confignetwork``, ``nicips``, ``nictypes``, ``nicnetworks`` and ``nicdevice`` attributes in ``nics`` table should be configured.
``nicdevice`` resolves relationships among physical_nics/BOND/VLAN/BRIDGE.
``nicdevices`` resolves relationships among physical_nics, BOND, VLAN, BRIDGE.
To use the nics table and confignetwork postscript to configure VLAN/BOND/BRIDGE on one or more nodes, here gives an example:
Following example will be used in the whole doc to describe how to use confignetwork postscript.
a. Physical nics are eth2 and eth3
b. Bonding eth2 and eth3 as bond0
c. From bond0, make 2 vlans: bond0.1 and bond0.2
d. Making bridge br1 using bond0.1, making bridge br2 using bond0.2, br1 ip is 10.0.0.1, br2 ip is 20.0.0.1
You should execute these steps:
Define configuration information for the BOND/VLAN/BRIDGE Adapters in the nics table

#. Using ``tabedit`` to edit the ``nics`` database table directly
The ``tabedit`` command opens the specified xCAT database table in a vi like editor and allows the user to edit any text and write the changes back to the database table.
