Brocade FastIron Ethernet Switch Platform and Layer 2 Switching Configuration Guide - Manual (Page 361)

NOTE
IP subnet VLANs are not the same thing as IP protocol VLANs. An IP protocol VLAN sends all IP
broadcasts on the ports within the IP protocol VLAN. An IP subnet VLAN sends only the IP subnet
broadcasts for the subnet of the VLAN. You cannot configure an IP protocol VLAN and an IP subnet
VLAN within the same port-based VLAN. This note also applies to IPX protocol VLANs and IPX network
VLANs, and to AppleTalk protocol VLANs and AppleTalk cable VLANs.
Default VLAN
By default, all the ports on a FastIron device are in a single port-based VLAN. This VLAN is called the
DEFAULT-VLAN and is VLAN number 1. FastIron devices do not contain any protocol VLANs or IP
subnet, IPX network, or AppleTalk cable VLANs by default.
The following figure shows an example of the default Layer 2 port-based VLAN.
