Configuring or editing a network interface
The information that you enter when you configure an interface is used to populate the network information fields when you perform operations on the Flex Appliance Console.
To configure or edit a network interface
- Before you edit an existing network interface, first make sure that it is not in use by any application instances or for replication, as follows:
Navigate to the Paired appliances section of the Remote replication page. Verify that the interface is not listed under Local appliance network interface.
If the interface displays in this field, edit the replication network to use a different interface. See Editing the replication network.
Navigate to the Application instances section of the System topology page. Click on each of your application instances and verify that the interface is not listed in the IP address and interface pairs field.
If the interface is listed for one or more instances, edit the network of each instance to remove the interface. You may need to add a different IP address and interface pair if the interface that you want to edit is the only interface that is assigned to the instance. See Editing instance network settings.
For both of these settings, if you do not have another available configured interface, use this procedure to configure an interface with placeholder values that you can use until you complete the edits.
- On the Flex Appliance Console, click the Network interfaces icon in the left-side navigation bar to open the Network interfaces page.
It may take a few minutes to load.
- Do one of the following to enter network information:
Note:
If you configure a network interface with both IPv4 and IPv6 addresses, all instances that use the interface must also be configured with both IPv4 and IPv6 addresses.
If you want to use VLAN tagging, select the network interface and click Add VLAN Tag. Then enter a VLAN ID between 1 and 4,094 and at least one subnet and gateway pair. Use CIDR notation for the subnet and gateway. For example, 1.1.1.0/24.
Do not enter the same VLAN ID or subnet and gateway pair for more than one interface.
Note:
If you have more than one node, you must set the VLAN tag for each node.
If you do not want to use VLAN tagging, click the name of the network interface, and then enter at least one subnet and gateway pair in CIDR notation. For example, 1.1.1.0/24.
Do not enter the same subnet and gateway pair for more than one interface.
Note:
The following subnets are reserved for internal use and cannot be used for the network interfaces:
192.168.227.0/24 and fdf8:192:168:227::/120
192.168.228.0/24 and fdf8:192:168:228::/120
192.168.229.0/24 and fdf8:192:168:229::/120
192.168.230.0/24 and fdf8:192:168:230::/120
- Click OK.
