WLC 5508 : Physical port devoted for a specific VLAN / function?

holzhirt1 — Sun, 04 Jul 2021 06:49:57 GMT

Hello,

We have currently a WLC 5508 using 8 ports bundled into an etherchannel.

We would like to remove one physical from this etherchannel and use it for providing an access to Internet only,

Is it possible to create an virtual interface on the WLC that points only on this port?

If yes what could be the best option ? (we would like to have a physical separation for the Internet traffic only and encrypt the capwapp up to the WLC).

Thanks for your advices,

Regards

Im afraid not. Once you LAG all the ports become (1). Only want is to break LAG and go PORTS.

It is not possible. It's either all in a LAG or now at all.

The best way is to have an anchor WLC. This way you can tunnel traffic to a guest anchor WLC located in the DMZ.

Thanks for your answers,

That means we would lose the whole LAG even if we break one interface?

And if we agree to do that we can achieve this ? But load-balancing won't be effective on the 7 other ports correct?

Otherwise what would be suggested to ensure a good separation for such purpose ?(using a minimum devices in between)

When you break LAG then each port is its own, meaning that you would tie say your data vlan to port 1. The Swicth port going to port 1 could be a truck and the data vlan is configured on this switch port and tagging. You could then add port 2 as a back up shoud port 1 go down.

As far as load balance traffic. You would turn off etherchannel on the switch side, so no.

Normally if you have 3 WLANs you can tie 1 to each WLC port, 1 - data, 2 - voice, 3 - medical.

Ok but we can have port 1 into a trunk and pass several VLANs into it ?

Yes of course. You could tie all your WLANs to port 1 if you like. Make sure you truck the switch port and dont signify a vlan ID on the port in the WLC.

Thank you all for your support in that matter,

I have now a better view on what's technically possible,

Kind regards
