Disabling STP on a VLAN
Once all of the interface ports have been configured for a VLAN, you can disable STP for all members
of the VLAN with a single command.
To disable STP for a VLAN, 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 select the VLAN interface number.
switch(config)# interface vlan 55
3. Enter the spanning-tree shutdown command to disable the spanning tree protocol on VLAN 55.
switch(conf-if-vl-55)# spanning-tree shutdown
Configuring an interface port as a Layer 2 switch port
To configure the interface as a Layer 2 switch port, 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 0/1
3. Enter the switchport command to configure the interface as a Layer 2 switch port.
4. Enter the do show command to confirm the status of the DCB interface. For example
switch(conf-if-te-0/1)# do show interface tengigabitethernet 0/1
5. Enter the do show command to confirm the status of the DCB interface running configuration.
switch(conf-if-te-0/1)# do show running-config interface tengigabitethernet 0/1
Configuring an interface port as an access interface
Each DCB interface port supports admission policies based on whether the frames are untagged or
tagged. Access mode admits only untagged and priority-tagged frames.
To configure the interface as an access 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 0/1
3. Enter the switchport command to make the interface a Layer 2 switch port.
switch(conf-if-te-0/1)# switchport
4. Enter the switchport command again to configure the DCB interface as a VLAN.
switch(conf-if-te-0/1)# switchport access vlan 20
Configuring an interface port as a trunk interface
Each DCB interface port supports admission policies based on whether the frames are untagged or
tagged. Trunk mode admits only VLAN-tagged frames.
To configure the interface as a trunk interface, run the following steps in privileged EXEC mode.
