LACP – Link aggregation control Protocol

  • Previously fell under 802.3ad, but now (around 2020) falls under 802.1ax.
  • Provides layer two link redundancy
  • Creates more bandwidth in a very cost effective way
  • Ports must be same speed and in full duplex
  • Both switching mode (family ethernet-switching) and routed mode (family inet) is supported
# Example LACP configuration on EX series switch: 
set interfaces ge-0/0/0 ether-options 802.3ad ae0
set interfaces ge-0/0/1 ether-options 802.3ad ae0

set interfaces ae0 vlan-tagging 
set interfaces ae0 aggregated-ether-options lacp active periodic fast
set interfaces ae0 unit 0 family ethernet-switching interface-mode trunk
set interfaces ae0 unit 0 family ethernet-switching vlan members vlan10

set vlan vlan10 vlan-id 10
