Uplink1 vs Uplink2 ?

Hakim

Hello,

In a pfsense with an internal switch, I have 2 uplinks associated with port 9 (uplink2) and 10 (uplink1).

If I set a VLAN 1234 interface and if I add a pfsense switch VLAN 1234 with the following members:

I can access equipments in my 1234 VLAN.

But if I use the Uplink2 (port 9), instead of the Uplink1, than I cannot access my equipments in my 1234 VLAN anymore.

Since uplink1 and 2 belongs to the same lagg0, I thought any of the 2 could work... :-/

I suppose that I should add both, but I am also trying to understand how it works.

If anyone can explain or point me to a place explaining this (I already read the doc "Switch port overview" but did not find my answer).

Thanks for your help,
Hakim
