Configuring Networking Settings

Configuring Networking Settings

You can configure the networking settings that were configured using the Initial System Configuration Wizard process for the DR Series system in the following tabs:

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.
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:
4.
Click Submit to set the new hostname for your system.
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.

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).

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.
ALB—Configures adaptive load balancing (ALB), which is the default setting.
802.3ad—Configures dynamic link aggregation using the IEEE 802.ad standard.
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:

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:

Eth1:

Eth2:

Eth3:

Managing the DR Series System Password

Managing the DR Series System Password

Resetting the Default System Password

You can manage the login password that is used when logging in to the DR Series system in two ways:

By modifying the existing login password using the Edit Password option in the System Configuration page. For more information, see Modifying the System Password.
By resetting the login password to its default value using the Reset Password option in the DR Series System Login page. For more information, see Resetting the Default System Password.

Modifying the System Password

Modifying the System Password

To configure a new password or to modify an existing password for logging in to the DR Series system, complete the following:

To change the system password, do one of the following:.
In the navigation panel, select System Configuration, the System Configuration page is displayed. Click Password Management.
In the navigation panel, select System Configuration > Password, the Password Management page is displayed.
2.
Click Edit Password.
The Edit Password dialog is displayed.
3.
In Current password, type the current password for the system.
4.
In New password, type the new system password.
5.
In Confirm password, retype the new password to confirm this as the new password replacing the existing system password.
6.
Click Change Password (or click Cancel to display the System Configuration page).
If successful, a Password change was successful dialog is displayed.
