In part III of this Cisco WLC Series, we’ll discuss IP and VLAN Planning, an unexceptional area in network design that often doesn’t get the level of treatement it deserves, in the context of wireless.
Any good IP and VLAN design needs to accomplish three goals.
- Able to support current needs
- Permits some degree of flexibility
- Creates a framework for security
These goals are no different for wireless. In the corporate network I support, the IP and VLAN Plan was established many years before wireless was given a serious seat at the table. Only by meeting the second goal that allows for flexibility, wireless was able to be overlayed with the wired network with enough degrees of separation to continue to meet the third goal of maintaining a security framework. Some of the decisions that go into a sustainable IP and VLAN Plan don’t require more than a few extra cycles of thought that readily pays for itself in unforseen ways.
