IP subnet, IPX network, and protocol-based VLANs within port-based
VLANs

If you plan to use port-based VLANs in conjunction with protocol-based VLANs, you must create the
port-based VLANs first. Once you create a port-based VLAN, then you can assign Layer 3 protocol
VLANs within the boundaries of the port-based VLAN. Generally, you create port-based VLANs to allow
multiple separate STP domains.

Suppose you need to provide three separate STP domains across an enterprise campus backbone.
The first STP domain (VLAN 2) requires a set of ports at each Layer 2 Switch location to be statically
mapped to IP only. No other protocols can enter the switches on this set of ports.

A second set of ports within STP domain VLAN 2 will be restricted to only IPX traffic. The IP and IPX
protocol VLANs will overlap on Port 1 of FSX-A to support both protocols on the same router interface.
The IP subnets and IPX network that span the two protocol VLANs will be determined by the FastIron
router configuration. The IP and IPX Protocol VLANs ensure that only the ports included in the each
Layer 3 protocol VLAN will see traffic from the FastIron router.
