AP123x & AP1251 second Ethernet port as downlink

Stellar AP's with 2 Ethernet ports (AP123x, AP1251), can we use the second Ethernet port as "downlink"? - as there is AP1201H with downlink feature, we hopefully can enable this on the two other models right?

HI, Only the AP1251 supports a downlink Ethernet port. On the AP123x both Ethernet ports are uplinks only.

ok, thanks
