+# VPP Link Aggregation Control Protocol (LACP) implementation {#lacp_doc}
+
+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
+enslave interface <interface> to <bond-interface-name> [passive] [long-timeout]"
+
+3. Delete the bond interface
+delete bond {<interface> | sw_if_index <sw_idx>}
+
+4. Detach the slave interface from the bond
+detach interface <interface>
+
+### Configuration example
+
+create bond mode lacp
+set interface state BondEthernet0 up
+enslave interface TenGigabitEthernet7/0/0 to BondEthernet1
+enslave interface TenGigabitEthernet7/0/1 to BondEthernet1
+enslave interface TenGigabitEthernet5/0/0 to BondEthernet1
+enslave interface TenGigabitEthernet5/0/1 to BondEthernet1
+
+detach interface TenGigabitEthernet5/0/1
+
+delete bond BondEthernet0
