WLC acting as a router??

[JPavonM]

Hi there,

We have one doubt about a question a customer has made us. Is it possible to create 2 WLAN, associate them to corresponding VLAN, but only trunking the management VLAN to the switches?

This scenario is for the WLC like been a router, because the WLC knows two VLAN with their ip addressing scheme in one side, and in the other side it's connected to the DMZ with an untagged VLAN, different from the other two.

I think it's not possible to deploy an scenario like this, but I'm not 100% sure, even with another manufacturer, but this is not the case.

Any help would be appreciated.

The WLC doesn't not act as a router and only bridges traffic.  What you can do is define port 1 of the WLC as primary for the management interface and for the guest interface define port 2 as the primary.  Now you can define the management as port 1 as the primary and port 2 as the backup and use port 3 as the primary for guest and port 4 as the backup for guest.  Then on the trunk port on the switch, only allow the management vlan on port 1 and 2 and guest vlan for port 3 and 4 on the switch.  You will still need a router for the guest vlan as the WLC will not do any NAT translations.

Thanks,

Scott
