Configure Additional Network Interfaces - confignetworkΒΆ
The confignetwork
postscript can be used to configure the network interfaces on the compute nodes to support Ethernet adapters, VLAN, BONDs, and BRIDGES. confignetwork
can be used in postscripts during OS privision, it can also be executed in updatenode
. The way the confignetwork
postscript decides what IP address to give the secondary adapter is by checking the nics
table, in which the nic configuration information is stored. In order for the confignetwork
postscript to run successfully, the following attributes must be configured for the node in the nics
table:
nicips
nictypes
nicnetworks
If configuring VLAN, BOND, or BRIDGES, nicdevices
in nics
table must be configured. VLAN, BOND or BRIDGES is only supported on RHEL.
nicdevices
- resolves the relationship among the physical network interface devices
The following scenarios are examples to configure Ethernet adapters/BOND/VLAN/Bridge.
Configure static install or application Ethernet adapters:
- Scenario 1: Configure Ethernet Network Interface
Configure BOND [RHEL]:
- Scenario 2: Configure Bond using two Ethernet Adapters
Configure VLAN [RHEL]:
- Scenario 3: Configure VLAN Based on Ethernet Adapter
- Scenario 4: Configure VLAN Based on Bond Adapters
Configure Bridge [RHEL]:
- Scenario 5: Configure Bridge Based On Ethernet NIC
- Scenario 6: Configure Bridge Based on Bond Adapters
- Scenario 7: Configure Bridge Based on VLAN
- Scenario 8: Configure Bridge Based on VLAN,VLAN use BOND adapter
