Configuring Physical Interfaces

After logging into the Data Domain UI, follow these steps to configure a physical interface:

1. Select Hardware > Ethernet > Interfaces.
2. Select an interface to configure.
3. Click Configure.
4. In the Configure Interface dialog box, determine how the interface IP address is to be set:
   • Use DHCP to assign the IP address: In the IP settings area, select Obtain IP Address using DHCP and choose either DHCPv4 for IPv4 access or DHCPv6 for IPv6 access.
     Note: If you choose to obtain the network settings through DHCP, you can manually configure the hostname at Hardware > Ethernet > Settings or with the "net set hostname" command. You must manually configure the hostname when using DHCP over IPv6.
   • Specify IP Settings manually: In the IP Settings area, select Manually configure IP Address. The IP Address and Netmask fields become active.
5. If you chose to manually enter the IP address, enter an IPv4 or IPv6 address. If you entered an IPv4 address, enter a netmask address.
   Note: You can assign just one IP address to an interface with this procedure. If you assign another IP address, the new address replaces the old address. To attach an additional IP address to an interface, create an IP alias.
6. Specify Speed/Duplex settings.
   Note: Speed and duplex cannot be set on DD3300, DD6400, DD6900, DD9400, and DD9900 systems.
7. Options:
   • Auto negotiate Speed/Duplex: Select this option to allow the network interface card to auto-negotiate the line speed and duplex setting for an interface.
   • Manually configure Speed/Duplex: Select this option to manually set an interface data transfer rate. Select the speed and duplex from the menus.
8. Specify the MTU (Maximum Transfer Unit) size for the physical (Ethernet) interface.
   • Click the Default button to return the setting to the default value.
   • Ensure that all your network components support the size set with this option.
9. Optionally, select Dynamic DNS Registration.
   Note: This option disables DHCP for this interface.
10. Click Next. The Configure Interface Settings summary page appears.
11. Click Finish and OK.

MTU Size Values

The MTU size must be set properly to optimize the performance of a network connection. An incorrect MTU size can negatively affect interface performance. Supported values for setting the maximum Transfer Unit (MTU) size for the physical (Ethernet) interface range from 600 to 9000 for IPv4, and 1280 to 9000 for IPv6. For 100 Base-T and gigabit networks, 1500 is the standard default.

Moving a Static IP Address

A specific static IP address must be assigned to only one interface on a system. A static IP address must be properly removed from one interface before it is configured on another interface.

1. If the interface that hosts the static IP address is part of a DD Boost interface group, remove the IP address from that group.
   Note: Add the new IP address back to the DD Boost interface group after this task is complete.
2. Select Hardware > Ethernet > Interfaces.
3. Remove the static IP address that you want to move.
   • Select the interface that is currently using the IP address you want to move.
   • In the Enabled column, select No to disable the interface.
   • Click Configure.
   • Set the IP Address to 0.
     Note: Set the IP address to 0 when there is no other IP address to assign to the interface. The same IP address must not be assigned to multiple interfaces.
   • Click Next, and click Finish.
4. Add the removed static IP address to another interface.
   • Select the interface to which you want to move the IP address.
   • In the Enabled column, select No to disable the interface.
   • Click Configure.
   • Set the IP Address to match the static IP address you removed.
   • Click Next, and click Finish.
   • In the Enabled column, select Yes to enable the updated interface.

Bonded Interface Creation

Create a bonded interface to support link aggregation or failover. The bonded interface serves as a container for the links to be aggregated or associated for failover.

Bonded Interface Configuration Guidelines

These guidelines apply to failover and aggregate bonded interfaces. There are additional guidelines that apply to either failover or aggregate interfaces but not both.

• The virtual-name must be in the form vethx where x is a number. The recommended maximum number is 99 because of name size limitations.
• You can create as many bonded interfaces as there are physical interfaces.
• Each interface used in a bonded interface must first be disabled. An interface that is part of a bonded interface is seen as disabled for other network configuration options.
• After a bonded interface is destroyed, the physical interfaces associated with it remain disabled. You must manually re-enable the physical interfaces.
• The number and type of cards installed determines the number of Ethernet ports available.
• Each physical interface can belong to one bonded interface.
• A system can support multiple mixed failover and aggregation-bonded interfaces, subject to the restrictions above.
• Bonded interfaces must be created from identical physical interfaces. For example, all copper, all optical, all 1 Gb, or all 10 Gb. However, 1 Gb interfaces support bonding a mix of copper and optical interfaces. This applies to bonded interfaces across different cards with identical physical interfaces.
• Failover links improve network resiliency.
• Aggregate links improve network performance and resiliency by using two or more network interfaces in parallel, thus increasing the link speed for aggregated links and reliability over that of a single interface.
• Remove functionality is available using the Configure button. Click a bonded interface in the list of interfaces on the Interfaces tab and click Configure. From the list of interfaces in the dialog box, clear the checkbox for the interface to remove it from bonding (failover or aggregate), and click Next.
• For a bonded interface, the bonded interface is created with the remaining secondary interfaces if the hardware for a secondary interface fails. If all the secondary interfaces fail, the bonded interface can no longer send and receive network traffic. This secondary interface hardware failure generates managed alerts, one per failed secondary interface.
  Note: The alert for a failed secondary interface disappears after the failed secondary interface is removed from the system. If new hardware is installed, the alerts disappear and the bonded interface uses the new secondary interface after the reboot.
• On DD3300, DD4200, DD4500, and DD7200 systems, the ethMa interface does not support failover or link aggregation.

Guidelines for Configuring a Bonded Interface for Link Aggregation

Link aggregation provides improved network performance and resiliency by using one or more network interfaces in parallel, thus increasing the link speed and reliability over that of a single interface. These guidelines are provided to help you optimize your use of link aggregation.

• It is recommended that you make interface changes only during scheduled maintenance downtime even though routing rules and gateways are reapplied after interface changes. Verify that the routing configuration is still correct after making interface changes.
• Enable aggregation on an existing bonded interface by specifying the physical interfaces and mode.
• Bring up the bonded interface and ensure that an IP address is on the interface or an associated interface. The bonded interface may have VLANs and/or aliases on it, each with an IP address, and therefore does not need an IP address directly on it to be fully functional.
• 1 GbE and 10 GbE interfaces cannot be aggregated together.
• 1 GbE copper and optical interfaces can be aggregated together.
• 10 GbE copper and optical interfaces cannot be aggregated together.

Creating a Bonded Interface for Link Aggregation

Create a bonded interface for link aggregation to serve as a container to associate the links that participate in aggregation.

1. Select Hardware > Ethernet > Interfaces.
2. In the Interfaces table, disable the physical interface where the bonded interface is to be added by clicking No in the Enabled column.
3. From the Create menu, select Virtual Interface.
4. In the Create Virtual Interface dialog box, specify a bonded interface name in the veth box.
5. In the Bonding Type list, select Aggregate.
6. In the Mode list, select a bonding mode.

   Options:

   • Round-robin: Transmit packets in sequential order from the first available link through the last in the aggregated group.
   • Balanced: Data is sent over interfaces as determined by the hash method selected.
   • LACP: Link Aggregation Control Protocol is similar to Balanced, except that it uses a control protocol that communicates to the other end and coordinates which links within the bond are available for use.
7. If you selected Balanced or LACP mode, specify a bonding hash type in the Hash list.
   • Options: XOR-L2, XOR-L2L3, or XOR-L3L4.
8. To select an interface to add to the aggregate configuration, select the checkbox that corresponds to the interface, and then click Next.
9. Enter an IP address, or enter 0 to specify no IP address.
10. Enter a netmask address or prefix.
11. Skip the Speed/Duplex options as they are ignored for bonding.
12. Specify the MTU setting.
    • Click Default to select the default value (1500).
    • Enter a different setting in the MTU box if needed.
13. Optionally, select Dynamic DNS Registration.
14. Click Next. The Configure Interface Settings summary page appears.
15. Click Finish and OK.

Guidelines for Configuring a Bonded Interface for Failover

Link failover provides improved network stability by identifying backup interfaces that can support network traffic when the primary interface is not operating. These guidelines are provided to help you optimize your use of link failover.

• A primary interface can be specified as part of the failover. If a primary interface removal is attempted from a failover, an error message appears.
• When the main secondary interface is used in a failover configuration, it must be explicitly specified and must also be a bonded interface to the bonded interface. If the primary interface goes down and multiple interfaces are still available, the next interface is randomly selected.
• All interfaces in a bonded interface must be on the same physical network. Network switches used by a bonded interface must be on the same physical network.
• The recommended number of physical interfaces for failover is greater than one. You can, however, configure one primary interface and one or more failover interfaces.

Creating a Bonded Interface for Link Failover

Create a bonded interface for link failover to serve as a container to associate the links that participate in failover.

1. Select Hardware > Ethernet > Interfaces.
