Usage Guidelines On the Brocade VDX family of switches, VLANs are treated as interfaces from a configuration point
of view. By default, all the DCB ports are assigned to VLAN 1 (VLAN ID equals 1). Valid VLAN IDs
are as follows:
• On Brocade VDX 8770 switches: 1 through 4086 for 802.1Q VLANs (VLAN IDs 4087
through 4095 are reserved on these switches), and 4096 through 8191 for service or
transport VFs in a Virtual Fabrics context.
• On all other Brocade VDX switches: 1 through 3962 for 802.1Q VLANs (VLAN IDs 3963
through 4095 are reserved on these switches), and 4096 through 8191 for service or
transport VFs in a Virtual Fabrics context.
ATTENTION
Brocade Network OS supports PVST+ and Riposting. The PVST and R-PVST protocols are proprietary
to Cisco and are not supported.
