Technical Tip: LACP support for entry level E-series
Description
Link Aggregation Control Protocol (LACP) is now supported on FortiGate and FortiWiFi-90E, 80E, 60E, 50E, and 30E.
Scope
FortiGate.
Solution
- Go to Network -> Interfaces.
- Select 'Create New' -> Interface.
- Set Type to '802.3ad Aggregate'.
- Configure the other settings as required.
- Select 'OK'.
Example:
To create a link aggregation interface from CLI:
configure system interface
edit "Aggregate Intf"
set vdom "root"
set type aggregate
set member "port 8" "port 10"
set device-identification enable
set lldp-transmission enable
set role lan
set snmp-index 13
next
end
To check the aggregate interface status:
FGT# diagnose netlink aggregate name "Aggregate Intf"

(A|I) - Aggregatable or Individual
(I|O) - Port In sync or Out of sync
(E|D) - Frame collection is Enabled or Disabled
(E|D) - Frame distribution is Enabled or Disabled
