Note: Always ensure that data source system (i.e. systems that send data to the DR4100) are located on the same subnet. Failure to do so will result in all traffic being sent to the first interface in the bond. This is because adaptive load balancing cannot properly load balance when data sources are located on a remote subnet. This is a result of ALB use of (ARP) which is subnet-specific and a router's inability to send ARP broadcast and updates. Figure 2 Adaptive load balancing By default, the DR4100 sets up bonding on its fastest interfaces. If the appliance is configured with NIC combo 3 (see Table 1) the 2x 10GB interfaces will become the new bond0. If the DR4100 is configured with combo 1, the 4x 1GB interfaces will become bond0. As of firmware 2.1 the default bond behavior can be changed by utilizing the auto_bonding_speed parameter. See below for usage example. To reset the default bond run the command: network --factory_reset [--auto_bonding_speed ] After resetting the interface the DR4100 will prompt you to enter a reboot command. Note: This command has to be issued from iDRAC, KVM or a local interface because it will disconnect any existing network connections. System -reboot 18 DR4100 Best Practice Guide | April 2014

Note:
Always ensure that data source system (i.e. systems that send data to the DR4100) are located on the same
subnet. Failure to do so will result in all traffic being sent to the first interface in the bond. This is because adaptive load
balancing cannot properly load balance when data sources are located on a remote subnet. This is a result of ALB use
of (ARP) which is subnet-specific and a router’s inability to send ARP broadcast and updates.

Adaptive load balancing
By default, the DR4100 sets up bonding on its fastest interfaces. If the appliance is configured with NIC combo 3 (
see
Table 1
) the 2x 10GB interfaces will become the new bond0. If the DR4100 is configured with combo 1, the 4x 1GB
interfaces will become bond0. As of firmware 2.1 the default bond behavior can be changed by utilizing the
auto_bonding_speed parameter. See below for usage example.
To reset the default bond run the command:
network --factory_reset [--auto_bonding_speed <1G|10G>]
After resetting the interface the DR4100 will prompt you to enter a reboot command
.
Note:
This command has to be issued from iDRAC, KVM or a local interface because it will disconnect any existing
network connections.
