2 To configure Bonding settings for your system, click Edit Bonding on the
options bar.
The Edit Bonding dialog is displayed.
3 Select the Bonding configuration for the system, choose one of the options
from the Bonding config list:
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 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 your data source systems reside on the same subnet as
the DR4000 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
DR4000 system may be lost unless you are sure that the system can accept this
bonding type.
4 Click Submit to configure the bonding option for your system (or click
Cancel to display the Networking page).
The Updated Bonding dialog is displayed when the selection is successful.
5 To configure a maximum transmission unit (MTU) setting for your
system, click Edit MTU on the options bar.
The Edit MTU dialog is displayed.
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. Internet Protocol subnetworks require that all hosts
in a subnet have an identical MTU.
