HA and LAG on LAN interfaces

fmde

Hello all,

Hope everyone is ok.

A quick (and probably dumy question), is that possible to set up 2 LAN interfaces in LAG mode in a HA infrastructure ?

To get something like this :

Thanks in advance and have a good day.

Hi, 
Yes, LAG + HA Pro can fulfill.
If Switch A & B support stacking (as a virtual switch), you can set LAG interface mode to 802.3ad(LACP).
Otherwise, set LAG interface mode to active-backup or balance-alb

Be aware, not all model support LAG interface.
As I know, USG310/1100/1900 support it.

Hi zyman2008,

Thanks for your reply.

There is a mistake on my dia, the switch A on the right side (WAN) is switch C... sorry.

Switch A and B don't support stacking unfortunately so active-backup mode was my first guest, thanks to confirm it

About the LAG support, I have 2 USG310 so all good.
