To TAG or not To TAG ....that is the question....

I've read all the 4400 series docs about five times over and some suggest to use untagged VLANs for the Management interface and others say to use tagged interfaces. Can anyone set me straight on the preferred method ???? Thanks!!!!

Re: To TAG or not To TAG ....that is the question....

There is no preferred method. It all comes back to the same point: "management interface" is not "management" in the sense of you managing the controller, but "management" in the sense of the controller managing the network.

Basically this means that your management interface should not be isolated in a "management VLAN" out of reach apart from Network admin machines, but should be reacheable from the network. Your APs will need it to discover the controller.

So some people say "therefore, leave it untagged", while some others say "no problem if you tag, as anyway you would tag most of your subnets, as long as all devices can be routed to it".
