Please run 'network -restart' for the changes to take affect. 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 DR4000 system.

administrator@mydr4000 > network --setdns --suffix
storage.local --primary 10.25.20.21 --secondary 10.25.20.25
If no options are specified, the following prompts are shown:
administrator@mydr4000 > network --setdns
--suffix missing: suffix for the DNS entry
--primary missing: primary DNS server
If options are specified, but no values provided, the following prompts are
shown:
administrator@mydr4000 > network --setdns --suffix
--primary
--suffix requires a value : --suffix <dns suffix> suffix for
the DNS entry
--primary requires a value : --primary <ip address> primary
DNS server
--setbonding [--mode <ALB | 802.3ad>, --mtu <number>]
To configure or update the bonding mode or to set the MTU number to use
for a DR4000 system, enter the example commands string at the system
prompt:
administrator@mydr4000 > network --setbonding --mode ALB
--mtu 1750
Bond device operation successful. Please run 'network --
restart' for the changes to take affect.
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
