Description

Use this command to configure tagged or untagged data traffic that does not match any
classification rule on a trunk port, supporting service, or transport VFs in a Virtual Fabrics context.

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.

Enter no switchport trunk default-vlan vlan_id to remove the default VLAN configuration.

Examples

Create a transport VF in a Virtual Fabrics context:

switch(config)# interface vlan 6000

switch(config-vlan-6000)# transport-service 60

Classify all nonmatching traffic except native VLAN traffic to the transparent default VLAN:

switch(config-if-te-2/0/1)# switchport trunk default-vlan 6000
