VPP Link Aggregation Control Protocol (LACP) implementation

This document is to describe the usage of VPP LACP implementation.

LACP

The Link Aggregation Control Protocol (LACP) is an 802.3ad standard which provides a protocol for exchanging information between Partner Systems on a link to allow their protocol instances to reach agreement on the Link Aggregation Group to which the link belongs and enable transmission and reception for the higher layer. Multiple links may be bundled to the same Aggregation Group to form a high bandwidth transmission medium and create a fault-tolerant link.

Configuration

  1. Create the bond interface create bond mode lacp [hw-addr <mac-address>] [load-balance { l2 | l23 | l34 }]
  2. Enslave the physical interface to the bond bond add <bond-interface-name> <slave-interface> [passive] [long-timeout]"
  3. Delete the bond interface delete bond {<interface> | sw_if_index <sw_idx>}
  4. Detach the slave interface from the bond bond del <slave-interface>

Configuration example

1 create bond mode lacp
2 set interface state BondEthernet0 up
3 bond add BondEthernet0 TenGigabitEthernet7/0/0
4 bond add BondEthernet0 TenGigabitEthernet7/0/1
5 bond add BondEthernet0 TenGigabitEthernet5/0/0
6 bond add BondEthernet0 TenGigabitEthernet5/0/1
1 bond del TenGigabitEthernet5/0/1
1 delete bond BondEthernet0
