1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the DCB interface type and slot/port number.
The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8 in VCS mode. The prompt for these ports is in the format:
switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/19
3. Enter the switchport command to place the DCB interface into trunk mode.
switch(conf-if-te-0/19)# switchport mode trunk
4. Specify whether all, one, or none of the VLAN interfaces are allowed to transmit and receive through
the DCB interface. Enter the one of the following commands as is appropriate for your needs.
Allowing only one VLAN to transmit/receive through the DCB interface
This example allows VLAN 30 to transmit/receive through the DCB interface.
switch(conf-if-te-0/19)# switchport trunk allowed vlan add 30
Allowing all VLANs to transmit/receive through the DCB interface
This example allows all VLANs to transmit/receive through the DCB interface.
switch(conf-if-te-0/19)# switchport trunk allowed vlan all
Excluding a VLAN from the DCB interface
This example allows all except VLAN 11 to transmit/receive through the DCB
interface.
switch(conf-if-te-0/19)# switchport trunk allowed vlan except 11
Blocking all VLANs from the DCB interface
This example allows none of the VLANs to transmit/receive through the DCB
interface.
switch(conf-if-te-0/19)# switchport trunk allowed vlan none
Disabling a VLAN on a trunk interface
To disable a VLAN on a trunk interface, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
2. Enter the interface command to specify the DCB interface type and slot/port number.
The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8 in VCS mode. The prompt for these ports is in the format:
switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/10
3. Enter the switchport command to place the DCB interface into trunk mode.
switch(conf-if-te-0/10)# switchport mode trunk none
4. Enter the switchport command again to remove the VLAN ranges from the trunk port.
switch(conf-if-te-0/10)# switchport trunk allowed vlan remove 30
