Multiple VLANs on a single interface
Hi, I've got a problem whereby I'm connecting multiple APs to a Netgear ProSafe GS728TP switch, and there's a requirement for SSIDs with different VLANs, but to be used on the same interface. ...

Well, as I said: IEEE Industry Standards! Don't blame me for the vendors "hiding" the effective under some fancy UIs.

What I haven't seen so far is an example of multiple VLANs used at the same time on the same interface. Sure we can tag ports 1-5 as VLAN 10, then 6-12 as VLAN 11, but can we configure Ports 1-5 as VLAN 10 and VLAN 11?
There is nothing that stops you. On the UI I've shown above, select the VLAN, e.g. 1, 10, and 11 to configure the port memberships for .... zero rocket science. Look here another VLAN on the very same switch:
Be careful: The UI does allow what is called an asymmetrical VLAN config on ports and LAGs - so please avoid overloading the ports with multiple Untagged settings. Reminder, the PVID does define the VLAN incoming frames on a port resp. LAG are associated to.

What you've shown me does make sense! I think it took some time to wrap my head around the GUI features for enabling this.
What would be the maximum number of VLANs you would suggest before overloading the ports?
The max number of supported VLAN is defined by the switch model, see e.g. the GS728TPv2, GS728TPPv2, GS752TPv2, GS752TPP Data Sheet , stating "16K MAC, 512 ARP, 256 VLANs". Nothing to overload.
Okay, thanks for the help!
