network --setdns [--suffix <dns suffix>] [--primary <IPv4/IPv6 address>] [--secondary <IPv4/IPv6 address>]

Syntax

network --setdns --suffix storage.local --primary 10.25.20.21 --secondary 10.25.20.25

network --setbonding --bondif <bondN> [--mode <ALB | 802.3ad>] [--mtu <supported MTU range 512 - 9000>]

Syntax

network --bondif bond1 --setbonding --mode ALB --mtu 1750

Result

Bond device operation successful. Please run 'network --restart' for the changes to take effect.

Note: ALB load balancing does not balance the load properly when the backup servers are on a remote subnet. This is because ALB uses the address resolution protocol (ARP) and ARP updates are subnet-specific. Because of this, 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 the data source systems reside on the same subnet as the DR Series system.

Note: When setting or changing the MTU value, make sure to verify that the Ethernet network switch is capable of supporting an MTU size that is equal to or larger than the value being set. Any mismatch in MTU values between the clients, the Ethernet network switch, and the DR Series system will make it inoperable. The relationship of jumbo frames to MTU is discussed in this topic.

Note: When using the DR Series system CLI --setbonding and --mtu commands, a warning dialog displays with the following message:

Incorrectly setting the MTU size will cause the DR4000 to not respond. You will 
need to log in to the system console and use the network --setbonding --bondif bond0 --mtu 1500 command 
to resolve the issue. Please verify that the switch is enabled and capable of supporting an MTU size 
that is equal to or larger than the value being set. Do you want to continue (yes/no) ?

CAUTION:

If the existing bonding setting is changed, the connection to the DR Series system may be lost unless you are sure that the DR Series system can accept this bonding type.

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 (NICs) also support jumbo frames.

Some computer manufacturers use 9000 bytes as the conventional limit for jumbo frame sizes. Internet Protocol (IP) subnetworks require that all hosts in a subnet have an identical MTU.

Consequently, interfaces that use a standard frame size and those that use a jumbo frame size should not be in the same subnet. To reduce the chance of interoperability issues, NICs capable of jumbo frames require special configurations to use jumbo frames. For more information, contact your Dell Support representative for assistance.

To verify that the destination system can support a specific frame size you want to attempt, use the following DR Series system CLI commands and specify the frame size in bytes using the following command as an example:

network --ping --destination <ip address> --size <number of bytes>

network --update

Syntax

 network --update [--bondif <bondN>]
                 [--nwif <ethN>]
                 [--mode < ALB | 802.3ad>]
                 [--name < DNS name >]
                 [--mtu  <Supported MTU range 512 - 9000>]


        --bondif   Bond interface to update.
        --nwif     Eth interface to update.
        --mode     Bonding mode to use.
        --name     DNS name for the interface.
        --mtu      Ethernet MTU to use (valid range is 512 - 9000).

For example, to update bond1 to use a different MTU parameter, run the command: network --update --bondif bond1 --mtu 5000

Result

WARNING: Incorrectly setting the MTU size will cause the DR appliance to not respond.

Please verify that the switch is enabled and capable of supporting an MTU size that is equal to or larger than the value being set.

Do you want to continue (yes/no) [n]? y

Interface update successful.
