  • 1.  8.10: Cannot get eth1 to be LAN

    Posted Jan 31, 2026 12:16 PM

    Hello,

    This is an iap325 running 8.10 and I'm trying to add eth1 to a bridge to be able to get wired dhcp on the same network/vlan as eth0, but I cannot get it to NOT show as WAN...? To simplify and try to understand, I have connected eth0 to an access-port, no trunking. Still does not work. What am I doing wrong?

    Have you tried setting the Eth1 as Downlink, and keep Eth0 as uplink? Be extra careful not to loop the L2 traffic.

    That is exactly what I'm trying do. It seems, whatever I do, eth1 shows up as WAN when "show uplink status". Specifying "no uplinik" in the profile I assign to eth1 has no effect. Also tried other variants. Running out of ideas...

    are you configuring it through CLI? what is the exact firmware version? also paste the output of "sh uplink status" and "sh uplink config"

    i suggest connect the E0 to a LAN switch with DHCP and confirm that the IAP works and then configure the E1 as downlink.

    I have a working setup with the ap, but now I want to add a cabled device that should get an ip from my router via dhcp. The ap has a static ip in the same network. Most of the config is done via cli.

    Here's some info:

    ap79# show ver:

    ArubaOS (MODEL: 325), Version 8.10.0.21 LSR

    ap79# show uplink status

    Uplink preemption             :enable

    Uplink preemption interval    :600

    Uplink enforce                :none

    Internet failover                        :disable

    Max allowed test packet loss             :10

    Internet check timeout (secs)            :10

    Setting uplink/downlink is an AP environment level setting, easiest done through the UI by editing the specific AP, navigating to the uplink option, and setting E1 to downlink.  Through the CLI you need to set the AP environment variable, which is not a configuration item, and then reboot the AP.

    ~ ap-env enet1_mode downlink

    ~ ap-env enet1_mode uplink

    I have an AP-305 running as a mesh point (wireless uplink) and the single Eth0 port serving as downlink to a PoE switch that provides power and connects to multiple downlink devices which all receive DHCP addresses.

    Beware, the downstream devices can time-out and revert to an APIPA 169.254 IP address if the mesh link isn't on line at boot-up... and they never retry at that point. I've had to make those devices static.

    None of my APs have a static address. Only the VC address is static. Despite recommendations, I've never had a problem using DHCP address reservations and it's much easier to manage addressing at the router. The VC is on a separate management VLAN. The mesh link trunks all VLANs and this isn't a problem (but does require CLI configuration).
