LINUX IFENSLAVE HANDSHAKE DRIVER DOWNLOAD

So you end up with a bond0 that is not configured according to its definition in the interfaces file. Ensure kernel support Before Ubuntu can configure your network cards into a NIC bond, you need to ensure that the correct kernel module bonding is present, and loaded at boot time. In this case, the bonding module is automatically loaded when the bond interface is brought up. This mode provides load balancing and fault tolerance. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the slaves in the bond such that different peers use different hardware addresses for the server.

Ensure kernel support Step 2: As another example, to combine eth0 and eth1 using the IEEE If the receiving slave fails, another slave takes over the MAC address of the failed linuc slave.

A general guideline is to: A different slave becomes active if, and only if, the active slave fails.

This probably causes the system to spawn a bond0 interface if it doesn’t exist yet. See Wikipedia for details.

This ifenslvae provides fault tolerance. Ethtool support in the base drivers for retrieving the speed and duplex of each slave. Transmit based on selectable hashing algorithm. Board index All times are UTC.

The receive load balancing is achieved by ARP negotiation. Finally, bring up your network again: Mode 1 active-backup Active-backup policy: Starting with Ubuntu 9.

Ethtool support in the base drivers for retrieving the speed of each linxu. In this case, the bonding module is automatically loaded when the bond interface is brought up. Mode 5 balance-tlb Adaptive transmit load balancing: I originally started with the configuration as shown in the post referenced where you provided some great input.

I expect this would create independent interfaces as soon as the system deems it necessary, and enslave them later when bond0 gets created. The outgoing traffic is distributed according to the current load computed relative to the speed on each slave.

From your traces, the wifi card doesn’t seem to be able to re-auth, it could be that the bond did not flip its MAC. The primary option affects the behavior of this mode. There is ifeenslave one route as expected – previous solutions defining the same IPs across eth0 and wlan0 create multiple routes and the routes are chosen based on priority eth0 wins by default. The bond0 is created kernel module loaded with the setup as desired showing eth0 is primary. Yet the problem with that might be that wlan0 is removable and might not be enslaved back if it is handshale in after bond0 is created.

This algorithm will place all traffic to a particular network peer on the same slave.
