Create Networking for Additional Interfaces

SBC instance includes establishing networking to the primary management interface, wancom0. You create networking for all other interfaces after deployment. Azure requires that you stop an SBC instance before you create and attach additional network interfaces. If not, Azure displays an error during interface configuration.

At a minimum, create the SBC s0p0 and s1p0 interfaces. This results in having 3 interfaces for the instance, including wancom0. If you create only 3 interfaces for the instance, the default setup will be wancom0, wancom1 and s0p0 at first bootup. Use the ACLI command interface-mapping to remap the interfaces. If you need accelerated networking for higher performance on media interfaces, use the Azure CLI to create the network. See Create a network interface with accelerated networking. Note these two caveats:
  • Accelerated networking is not supported for management interfaces.
  • If enabled, accelerated networking must be enabled for all media interfaces.

Otherwise, when you select an instance from the portal, Azure displays an instance-specific navigation pane on the left side of the dialog. Begin each interface configuration as follows:

  1. Click the Settings, Networking link.
  2. At the top of the interface configuration dialog, click the Attach Network Interface link.
  3. Within the Attach Network Interface dialog, click the Create Network interface link.

Create Network interface

Configure the applicable Create Network interface fields, including:

  • Enter a distinguishable name in theName field.
  • Select the correct subnet from the Subnet dropdown field.
  • Set the Private IP assignment setting to Static.
  • Set the Private IP address to an address within the subnet.

Security Groups

The Create Network interface dialog includes the Network security group selection tool. By default, all network interfaces are set to deny all traffic. You assign security groups to each of the media interfaces to specify the traffic you want to allow. Assuming you have created these groups as a pre-requisite to instance deployment, you simply select the appropriate group from Create Network interface dialog.

Bear in mind that the SBC has its own traffic control configurations. Ensure that the Azure network interface and SBC configurations do not conflict.

Attach Network Interfaces to the SBC

Upon completing the configuration of the Create Network interface fields, you also attach them to your instance. Azure creates MAC addresses upon interface creation. Note these addresses so you can later verify they are attached to the correct SBC, as described below.

Restart the SBC

Start your instance after creating and attaching all interfaces. Use the instance's Serial Console to connect to the virtual COM1 serial port. After bootup, proceed with setting your SBC passwords from the SBC command line interface.
