Link Aggregation Groups
This chapter provides information on how to configure a Link Aggregation Group (LAG). For LAGcontrol,
FortiSwitch supports the industry-standard Link Aggregation Control Protocol (LACP).
FortlSwitch supports LACPprotocol in active and passive modes.
In active mode, you can optionally specify the mininum and maximum number of active members in a trunk
group.
FortlSwitch supports flap guard protection for switch ports in a LAG.
Configuring the Trunk and LAG Ports
It is important to configure the trunk to prevent loops.
Using the web-based manager:
1.
Go to Switch > Port > Trunk and select Create Trunk.
2. Give the trunk an appropriate name.
3.
Set Mode to either static, lacp-active or lacp-passive.
4.
Add the required ports to the Members list.
5.
Select OK.
Using the CLI:
config switch trunk
edit <trunk name>
set description <description_string>
set mode {lacp-active | lacp-passive | static}
set member-withdrawal-behaviour {block | forward}
set lacp-speed {fast | slow}
set bundle [enable|disable]
set min_bundle <integer>
set max_bundle <integer>
set port-selection-criteria
{src-ip | src-mac | dst-ip |dst-mac | src-dst-ip |src-dst-mac}
end
end
