Seven Nic binding modes

Author: User

There are seven Nic binding modes:
1. mode = 0 round-robin
2. mode = 1 active-backup
3. mode = 2 load balancing (xor)
4. mode = 3 fault-tolerance (broadcast)
5. mode = 4 lacp
6. mode = 5 transmit load balancing
7. mode = 6 adaptive load balancing
 
(1) Round-robin policy, with the pattern code 0. This policy transmits data packets sequentially until the last device. This mode provides load balancing and fault tolerance capabilities.
 
(2) Active-backup policy. The mode code is 1. This policy only allows one device to process data. When it goes down, it will be replaced by backup, which only provides Fault Tolerance capabilities.
 
(3) XOR policy, with the pattern Code 2. This policy selects the transmission device based on the MAC address's exclusive or operation results to provide load balancing and fault tolerance capabilities.
 
(4) Broadcast policy. The mode code is 3. This policy transmits all data through all devices to provide Fault Tolerance capabilities.
 
(5) IEEE 802.3ad Dynamic link aggregation (IEEE 802.3ad Dynamic link aggregation), with the pattern code 4. This policy shares the same transmission speed by creating an aggregation group. The switch must also support the 802.3ad mode to provide fault tolerance.
 
(6) Adaptive transmit load balancing. The mode code is 5. This policy distributes the sent data to each device based on the current load and processes the received data by the currently used device. The channel combination in this policy does not require dedicated switch support, and provides load balancing and fault tolerance capabilities.
 
(7) Adaptive load balancing, with the pattern Code 6. In IPV4, this policy includes the load balancing policy transmitted by the adapter. The load received by ARP negotiation is completed. The channel and the driver intercept the requests sent by ARP in the local system, overwrite the original address of the sub-device with the hardware address of one of the devices.
 
Bonding modes:
Balance-rr
Transmissions are supported Ed and sent out sequentially on each bonded slave interface. This mode provides fault tolerance and load balancing.
Active-backup
Only one slave in the bond is active. Another bonded slave interface is only used if the active bonded slave interface fails. This mode provides fault tolerance.
Balance-xor
Transmission is based on the following equation: [(the source MAC address XORd with the destination MAC address) modulo (slave count)]. this selects the same slave for each destination MAC address. this mode provides fault tolerance and load balancing.
Broadcast
Transmits everything on all slave interfaces. This mode provides fault tolerance.
802.3ad
IEEE 802.3ad Dynamic link aggregation. creates aggregation groups that share the same speed and duplex settings. utilizes all slaves in the active aggregator according to the 802.3ad specification. requires a switch that supports IEEE 802.3ad Dynamic link aggregation.
Balance-tlb
Channel bonding that does not require any special switch support. the outgoing traffic is distributed according to the current load (computed relative to speed) on each slave. incoming traffic is already ed by the current slave. if the processing ing slave fails, another slave takes over the MAC address of the failed locking slave. this mode provides fault tolerance and load balancing.
