Dell PowerVault DR2000v - Manual (Page 41)

network --setdns [--suffix <dns suffix>] [--primary <IPv4/IPv6 address>] [--secondary
<IPv4/IPv6 address>]
Description
Configures the domain name system (DNS) for a DR Series system, which includes the corresponding DNS suffix and a
primary name server IP address (and optionally, a secondary name server IP 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>]
Description
Configures or updates the bonding mode or sets the maximum transmission unit (MTU) number to use for a DR Series
system.
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).
