    I have an Aruba Instant AP setup.

    I setup three SSIDs, one for each vlan: Internal(vlan 1), DMZ(vlan 3) and Guest(vlan 7).

     

    The aruba is connected to a switch. Connected to a trunk port. It has vlan 3 Untagged and vlans 1 and 7 Tagged.

     

    On the Aruba. I have the DMZ(3) set to the default vlan and it connects to the internet, but the Internal(1) and Guest(7) do not.

    I created a DHCP scope for vlan 1 and vlan 7 and they do pull the correct IP addresses.

     

    Are there any settings I'm missing?

    Any port can only be a member of One tagged VLAN. However a port can be a member of multiple untagged VLANs.

    Totally wrong. It's the contrary!

     

    Any port can be an untagged member of one and only one VLAN, however a port can (also) be a tagged member of other multiple VLANs.

    I stand corrected. My deepest apologies.

    That is how I have it set up. Only one Untagged with multiple Tagged on the port the aruba is connected to. Only the Untagged passes traffic successfully.

    mgcook,

    Have you seen this thread? It talks about VC assisgned DHCP addressing.
