If Gateways are to be deployed with an OAM interface, complete the following steps.
- Add an additional interface to the VM (ETH2).
VMware: If a dedicated VNIC for Management/OAM is desired, add another vNIC of type vmxnet3. You must repeat the previous step, which is to click OK and then Edit Settings again so you can make a note of the vNIC MAC address.
KVM: If a dedicated VNIC for Management/OAM is desired, make sure you have a libvirt network named oam-network. Then add the following lines to your XML VM structure:
….. </controller> <interface type='network'> <source network='public_interface'/> <vlan><tag id='#public_vlan#'/></vlan> <alias name='hostdev1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x11' function='0x0'/> </interface> <interface type='network'> <source network='inside_interface'/> <alias name='hostdev2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x12' function='0x0'/> </interface> <interface type='network'> <source network='oam_interface'/> <vlan><tag id='#oam_vlan#'/></vlan> <alias name='hostdev2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x13' function='0x0'/> </interface> <serial type='pty'> <source path='/dev/pts/3'/> <target port='0'/> <alias name='serial0'/> </serial>
- Configure the network-config file with the additional interface.
