Create a Backbone Virtual Circuit
This article covers how to create a backbone virtual circuit. For information on our other virtual circuit options, see:
You need at least two provisioned ports to create a backbone connection. For more information, see Create a Port.
Create a backbone connection
Log in to the PacketFabric portal. From the dashboard, click Virtual Circuit under Create Services:
Select Backbone Connection.
Complete the following fields:
Select Source Interface
Select your source interface.
Click Toggle Details to view information about any virtual circuits already associated with that port.
Select Destination Interface
Select your destination interface.
Unlike when creating a dedicated point-to-point connection, the speed and optic do not have to match the source interface.
Select Pricing Plan
Select a billing account and then one of the following options:
- Long-haul Dedicated
- You are billed a set amount each month, regardless of how much data you transfer.
If you select this option, you are also asked to specify the speed and contract length.
IMPORTANT: At this time, we only limit the speeds you can select to the lowest speed between your source and destination interfaces. For example, if you are building a virtual circuit between a 1 Gbps port and a 10 Gbps port, you cannot select more than 1 Gbps as your speed.
However, you are ultimately responsible for not overburdening your ports (for example, creating three 10 Gbps virtual circuits between two 10 Gbps ports). Keep that in mind as you select a speed.
If you select a low speed and later decide you want more capacity, you can upgrade your virtual circuit. If you allocate too much capacity, you can later set or edit rate limits for the circuit.
You can view the speeds for each virtual circuit associated with a port from the port details page.
- Long-haul Usage-based
- You are billed based on how much data you transfer. This is a month-to-month plan.
- VC Description
- Provide a meaningful name for the virtual circuit.
- VC Parameters
- Specify a VLAN ID for both your source and destination interfaces or disable VLAN tagging. At least one end must have a VLAN tag.
You can manually enter the ID or click Next Available. If you click Next Available, we find the highest in-use VLAN ID and increment by one. For example, if the highest in-use ID is 15, this field autopopulates with 16. By default, these fields are already populated with the next available VLAN ID. You can always change VLAN IDs by editing the virtual circuit.
TIP: Expand Advanced Configuration Options below to review prior VLAN ID allocations.
IMPORTANT: If you are planning to provision multiple virtual circuits on the selected ports, you must keep VLAN tagging enabled for both ends.
Advanced Configuration Options
Optionally, you can limit your data transfer rates to below your port capacities.
Note that you are still billed by capacity, not your rate limit.
