You can change the network configurations of a dedicated load balancer as needed.

Binding or Unbinding an IP Address

You can bind or unbind an IPv4 EIP, a private IPv4 address, or an IPv6 address, to or from a dedicated load balancer as required.

NOTE:

Load balancers without IPv4 EIPs cannot route requests over the public IPv4 network.
Load balancers without private IPv4 addresses cannot route requests over the private IPv4 network.
Load balancers without IPv6 addresses cannot route requests over the IPv6 network.
If you want to enable a load balancer to communicate with the Internet through a global EIP, you can bind a global EIP to the load balancer.

Changing an IP Address

Before changing the private IPv4 address or IPv6 address bound to a dedicated load balancer, note the following:

The new IPv4 IP address can be in the current subnet or a different subnet.
The new IPv6 IP address must be in a different subnet with IPv6 enabled.

Changing a Private IPv4 Address
Changing an IPv6 Address

Go to the load balancer list page.
On the displayed page, locate the load balancer and choose More > Change Private IPv4 Address in the Operation column.
In the Change Private IPv4 Address dialog box, select the subnet where the IP address resides and specify an IP address.
- To use an IP address in another subnet, if you select Automatically assign IPv4 address, an IPv4 address will be assigned to your load balancer.
- To use another IP address from the current subnet, specify an IP address.
Click OK.

Go to the load balancer list page.
On the displayed page, locate the load balancer and choose More > Change IPv6 Address in the Operation column.
In the Change IPv6 Address dialog box, select a different subnet where the IP address resides and specify an IP address.
The system will automatically assign an IPv6 address to the load balancer from the subnet you select.
Click OK.

Go to the load balancer list page.
On the displayed page, locate the load balancer and choose More > Change Private IPv4 Address in the Operation column.
In the Change Private IPv4 Address dialog box, select the subnet where the IP address resides and specify an IP address.
- To use an IP address in another subnet, if you select Automatically assign IPv4 address, an IPv4 address will be assigned to your load balancer.
- To use another IP address from the current subnet, specify an IP address.
Click OK.

Go to the load balancer list page.
On the displayed page, locate the load balancer and choose More > Change IPv6 Address in the Operation column.
In the Change IPv6 Address dialog box, select a different subnet where the IP address resides and specify an IP address.
The system will automatically assign an IPv6 address to the load balancer from the subnet you select.
Click OK.

Modifying the Bandwidth

If you set the Network Type of a load balancer to Public IPv4 network or IPv6 network, the load balancer can route requests over the Internet and you can modify the bandwidth used by the EIP bound to the load balancer as required. When you modify the bandwidth, traffic routing will not be interrupted.

NOTE:

When modifying bandwidth, you need to change the specifications of the dedicated load balancer to avoid speed limit due to insufficient bandwidth.
The EIP bandwidth defines the limit for clients to access the load balancer.

Go to the load balancer list page.
On the displayed page, locate the load balancer and click More in the Operation column.
Click Modify IPv4 Bandwidth or Modify IPv6 Bandwidth.
In the New Configuration area, modify the billing option and bandwidth and click Next.
You can select the bandwidth defined by the system or customize a bandwidth. The bandwidth ranges from 1 Mbit/s to 2,000 Mbit/s.
Confirm the new bandwidth and click Submit.
NOTE:

After you change the billing option and bandwidth, the price will be recalculated accordingly.

Adding or Removing an IPv6 Address to or from a Shared Bandwidth

If the IPv6 address of a load balancer is added to a shared bandwidth, the load balancer can route requests over the Internet.

You can add or remove an IPv6 address to or from a shared bandwidth.

NOTE:

If the IPv6 address of a load balancer is removed from a shared bandwidth, the load balancer can only route requests within a VPC.

Go to the load balancer list page.
On the displayed page, locate the load balancer and click More in the Operation column.
1. Adding an IPv6 address to a shared bandwidth
  1. Click Add to IPv6 Shared Bandwidth.
  2. In the Add to IPv6 Shared Bandwidth dialog box, select the shared bandwidth to which you want to add.
    If no shared bandwidths are available, assign one as prompted.
2. Removing an IPv6 address from a shared bandwidth
  1. Click Remove from IPv6 Shared Bandwidth.
  2. In the displayed dialog box, confirm the shared bandwidth you want to remove.
Click OK.
