To configure new networking settings (or to change from those set using the Initial System Configuration Wizard), complete the following:

1.
Select System Configuration > Networking.
The Networking page is displayed. Select settings for hostname, IP Address, DNS, Bonding, or to view the Ethernet port settings (Eth0-Eth3) for the DR Series system.
◦
To configure hostname, skip to step 2.
◦
To configure IP addressing, skip to step 5.
◦
To configure DNS, skip to step 10.
2.
To change the current Hostname, select the Hostname tab and click Edit Hostname on the options bar.
The Edit Hostname dialog is displayed.
3.
Type a hostname in Hostname that meets the following supported character types and length:
◦
Alphabetic—allows A-Z, a-z, or a combination of upper and lower case alphabetic characters.
◦
Numeric—allows numerals zero (0) through 9.
◦
Special characters—allows only the dash (-) character.
◦
Length limit—hostnames cannot exceed the maximum length of 19 characters.
4.
Click Submit to set the new hostname for your system.
5.
To change the current IP address settings for the selected NIC bond or Ethernet port, select the Interfaces tab and click Edit Interfaces on the options bar.
The Edit Interface — <bond or Ethernet port number> dialog is displayed.
6.
Under IP Address, in Mode, select Static (to set static IP addressing for your system), or select DHCP (to set dynamic IP addressing for your system).
 
NOTE: To select the DHCP mode of IP addressing, select DHCP, and click Submit. The remaining substeps in this step only need to be completed if you selected the Static mode of IP addressing for the DR Series system.
a.
In New IP Address, type an IP address that represents the new IP address for your system.
b.
In Netmask, type an netmask address value that represents your system (the system IP address and netmask identify the network to which your system belongs).
c.
In Gateway, type an IP address for the gateway associated with your system.
7.
Under MTU, in MTU, enter the value you want to set as the maximum.
 
NOTE: Ensure that the value that you enter in MTU is the same for the clients, Ethernet Switch, and the appliance. The connection between the clients, the Ethernet switches, and the appliance will break if the MTU number is not the same on all the components.
 
NOTE: In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of payload (but in some cases, jumbo frames can carry up to 9000 bytes of payload). Many Gigabit Ethernet switches and Gigabit Ethernet network interface cards support jumbo frames. Some Fast Ethernet switches and Fast Ethernet network interface cards also support jumbo frames.

Some computer manufacturers use 9000 bytes as the conventional limit for jumbo frame sizes. To support jumbo frames used in an Internet Protocol subnetwork, both the host DR Series system (initiator or source) and the target DR Series system have to be configured for 9000 MTU.

Consequently, interfaces using a standard frame size and those using the jumbo frame size should not be in the same subnet. To reduce the chance of interoperability issues, network interface cards capable of supporting jumbo frames require specific configurations to use jumbo frames.

To verify that the destination system can support a specific frame size, use the DR Series system CLI command network --ping --destination <IP address> --size <number of bytes>.

For more information, contact Dell Support for assistance (for details, see Contacting Dell).

 
NOTE: Make sure that if you are using any Dell network switches that you take full advantage of the latest switch firmware upgrades and application notes. The application notes provide procedures that assist you in performing switch firmware upgrades and saving configuration files (for complete details, see support.dell.com/ and navigate to Drivers and Downloads for your system type).
 
NOTE: When setting or changing the MTU value, make sure that you verify that the Ethernet network switch is capable of supporting an MTU size that is equal to or larger than the value you are setting. Any mismatch in MTU values between the clients, Ethernet network switch, and the DR Series system appliance will make it inoperable.

Dell suggests that you observe standard best practices when deploying jumbo frames in networks, and recommends using jumbo frames with the DR Series system because this frame size typically provides the best performance. However, for networks that do not support jumbo frames, the DR Series system also supports using the standard frame size.

8.
Under Bonding, from the Bonding configuration list, select the appropriate bonding configuration.
 
NOTE: You may lose the connection to the system if you change the bonding configuration. Change the bonding configuration only if the system accepts the new bonding type.
◦
ALB—Configures adaptive load balancing (ALB), which is the default setting.
 
NOTE: ALB load balancing does not balance the load properly when your backup servers are on a remote subnet. This is because ALB uses the address resolution protocol (ARP) and ARP updates are subnet-specific. Because this is the case, ARP broadcasts and updates are not sent across the router. Instead, all traffic is sent to the first interface in the bond. To resolve this ARP-specific issue, make sure that your data source systems reside on the same subnet as the DR Series system.
◦
802.3ad—Configures dynamic link aggregation using the IEEE 802.ad standard.
 
CAUTION: If you change the existing bonding setting, the connection to the DR Series system may be lost unless you are sure that the system can accept this bonding type.
9.
Click Submit to have the DR Series system accept the new values (or click Cancel to display the Networking page).
The Updated IP Address dialog is displayed when the selection is successful (if you change the static IP address manually, you need to use this IP address in the browser when you log back into the DR Series system).
10.
To configure DNS settings for your system, select the DNS tab and click Edit DNS on the options bar.
The Edit DNS dialog is displayed.
11.
In Domain Suffix, type a domain suffix to use.
For example, acme.local. This is a required field.
12.
In Primary DNS, type an IP address that represents the primary DNS server for your system; this is a required field.
13.
For Secondary DNS, type an IP address that represents the secondary DNS server for your system; this is an optional field.
14.
Click Submit to have the DR Series system accept the new values (or click Cancel to display the Networking page).
The Updated DNS dialog is displayed when the selection is successful.

Networking Page and Ethernet Port Values

Networking Page and Ethernet Port Values

The Networking page displays the currently configured multiple Ethernet ports for the DR Series system in a series of panes. For 1–Gigabit Ethernet (GbE) ports in the DR4000 system this could be Eth0, Eth1, Eth2, and Eth3, and in the DR4100 system this could be Eth0, Eth1, Eth2, Eth3, Eth4, and Eth5. For 10-GbE/10-GbE SFP+ NICs, this means that the two ports are bonded together into a single interface. For example, the DR Series system port configuration is as follows:

In a 1-GbE NIC configuration: the DR4000 system supports up to four 1–GbE ports, which consists of up to two internal LAN on Motherboard (LOM) ports and two ports on an expansion card that are bonded together. The DR4100 system supports up to six 1–GbE ports, which consists of up to four internal LOM ports on the network daughter card (NDC) and two ports on a PCI Express expansion card.
•
In a 10-GbE or 10-GbE SFP+NIC configuration: the DR4000 system supports up to two 10–GbE or 10–GbE SFP+ ports on an expansion card that are bonded together. The DR4100 system supports up to two 10-GbE or 10-GbE SFP+ ports that reside on the NDC that are bonded together.
 
NOTE: For more information on advanced networking options see the Command Line Interface Guide available at dell.com/support/manuals.

The ports for bonded NICs display: MAC address, port speed in megabtyes per second (MB/s), maximum speed, and duplex setting. The following example shows Ethernet port values for the four ports in a 1-GbE NIC bonded configuration on a DR4000 system:

Eth0:
