By default, the combined vSphere Replication appliance has one VM network adapter that is used by the vSphere Replication server for replication traffic, and by the vCenter Server for virtual machine management.
The IP address that is used for vSphere Replication management traffic is localhost 127.0.0.1. Because the default VM network adapter is used for different types of traffic, you can add a second adapter to the appliance, and configure vSphere Replication to use the second adapter only for incoming replication traffic.
Verify that the vSphere Replication virtual appliance is deployed and registered with the vCenter Server.
- Power off the vSphere Replication appliance and edit the VM Hardware settings to add a new VM NIC.
- Right-click the VM and select Edit Settings.
- From the New Device drop-down menu at the bottom of the Virtual Hardware tab, select Network, and click Add.
The new network adapter appears in the list of devices at the right.
- Expand the properties of the new network adapter to verify that Connect At Power On is selected.
You can assign a static MAC address or leave the text box empty to obtain an IP address automatically.
- Click OK to close the Edit Setting dialog box.
- Power on the vSphere Replication appliance.
- From the Summary tab of the vSphere Replication appliance, take a note of the IP address of the new network adapter.
You can click View all XX IP addresses to check the IP address of the new NIC.
- Use a supported browser to log in to the vSphere Replication VAMI.
The URL for the VAMI is https://vr-appliance-address:5480.
- On the VR tab, click Configuration.
- In the IP Address for Incoming Storage Traffic text box, enter the IP address of the new network adapter that you added.
- Click Apply Network Settings.
The vSphere Replication appliance uses the IP address that you assigned only for incoming replication traffic.
