LACP Protocol
=============
This document is to describe the usage of VPP Link Aggregation Control
Protocol (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 ]
[load-balance { l2 \| l23 \| l34 } [numa-only]]
2. Enslave the physical interface to the bond bond add [passive]
[long-timeout]”
3. Delete the bond interface delete bond { \| sw_if_index }
4. Detach the slave interface from the bond bond del
Configuration example
~~~~~~~~~~~~~~~~~~~~~
::
create bond mode lacp
set interface state BondEthernet0 up
bond add BondEthernet0 TenGigabitEthernet7/0/0
bond add BondEthernet0 TenGigabitEthernet7/0/1
bond add BondEthernet0 TenGigabitEthernet5/0/0
bond add BondEthernet0 TenGigabitEthernet5/0/1
::
bond del TenGigabitEthernet5/0/1
::
delete bond BondEthernet0
