2019-09-06bonding: add weight support for active-backup modeSteven Luong1-1/+19
Not all interfaces have the same characteristics within the bonding group. For active-backup mode, we should do our best to select the slave that performs the best as the primary slave. We already did that by preferring the slave that is local numa. Sometimes, this is not enough. For example, when all are local numas, the selection is arbitrary. Some slave interfaces may have higher speed or better qos than the others. But this is hard to infer. One rule does not fit all. So we let the operator to optionally specify the weight for each slave interface. Our primary slave selection rule is now 1. biggest weight 2. is local numa 3. current primary slave (to avoid churn) 4. lowest sw_if_index (for deterministic behavior) This selection rule only applies to active-backup mode which only one slave is used for forwarding traffic until it becomes unreachable. At that time, the next "best" slave candidate is automatically promoted. The slaves are sorted according to the preference rule when they are up. So there is no need to find the next best candidate when the primary slave goes down. Another good thing about this rule is when the down slave comes back up, it is selected as the primary slave again unless there is indeed a "better" slave than this down slave that were added during that period. To set the weight for the slave interface, do this after the interface is enslaved set interface bond <interface-name> weight <value> Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I59ced6d20ce1dec532e667dbe1afd1b4243e04f9
2019-07-19bonding: add support for numa-only in lacp modeZhiyong Yang1-1/+5
If numa-only is set, Only slaves on local numa node transmit pkts if have at least one, otherwise the bond interface works as usual. CLI change: create bond mode lacp [load-balance { l2 | l23 | l34 } {numa-only}] [hw-addr <mac-address>] [id <if-id>] The new member "u8 numa_only;" is also added to bond_create_if_args_t.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+163
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
