NIC Bonding Flashcards
How would you configure NIC Bonding?
NIC bonding/teaming are the same thing. Is a process of combing or joining two or more physical NICs to make one logical NIC on the system.
With the purpose if one physical NIC fails the second physical NIC will kick in and ensure the server connection does not stop.
What is runner?
*Runners are the different modes of NIC/bonding.
*Also called teamd modes.
Can you say any two different modes of NIC Bonding?
*activebackup- most commonly used teamd mode. Is one physical card/link/port is active taking request and the other is backup inactive/passive.
*loadbalance is a mode if one NIC is less busy compared to the other it will send the traffic request to the less busy one disbruted evenly.
*roudrobin - in this mode traffic is sent across the ports/links of the logical NIC sequentially, doesn’t check if the port/links are busy or not, for high performance use round Robin, large traffic request are split in half and sent across the ports.
What do you mean by Activebackup NIC bonding?
Mode=1 This mode is based on Active-backup policy.
*one physical card/link/port is active taking requests and the other us backing up inactive/passive.
*the passive/inactive physical NIC becomes active when the first active NIC fails to route traffic .
*this mode promotes fault tolerance- one physical NIC can fail buy not all, ensures server is up 100%, no downtime, high upkeep cost, strong redundancy.
*also called active passive.
What is the loadbalance type of NIC Bonding?
*in this mode if one NIC is less busy compared to the other, it will send the traffic requests to the less busy one,distributes evenly.
*loadbalance checks which NIC is taking most request
*loadbalance checks the health of the NIC , if the health of a NIC is deteriorate it will send stop sending traffic to that NIC.
*in this mode all physical NICs you have are active/active.
