Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 427)

The gigabitethernet rbridge-id/slot/port keyword is used only for the Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8. 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 no shutdown command to enable the DCB interface.
switch(conf-if-te-0/1)# no shutdown
4. Enter the spanning-tree command to enable guard root on a DCB interface.
switch(conf-if-te-0/1)# spanning-tree guard root
5. Enter the spanning-tree command to enable guard root for a specific VLAN.
switch(conf-if-te-0/1)# spanning-tree guard root vlan 10
Specifying the STP hello time (DCB)
From the DCB interface, use this command to set the time interval between BPDUs sent by the root
switch. Changing the hello time affects all spanning tree instances.
The max-age setting must be greater than the hello-time setting (refer to Specifying the bridge
maximum aging time on page 421). The range is 1 through 10 seconds. The default value is 2 seconds.
To specify the MSTP hello time on a DCB 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. 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 no shutdown command to enable the DCB interface.
switch(conf-if-te-0/1)# no shutdown
4. Enter the spanning-tree command to specify the hello time on a DCB interface.
switch(conf-if-te-0/1)# spanning-tree hello-time 5
5. Return to privileged EXEC mode.
switch(conf-if-te-0/1)# end
6. Enter the copy command to save the running-config file to the startup-config file.
switch# copy running-config startup-config
Specifying restrictions for an MSTP instance (DCB)
From the DCB interface, use this command to specify restrictions on the interface for an MSTP
instance.
To specify restrictions for an MSTP instance on a DCB interface, perform the following steps.
1. Enter the configure terminal command to access global configuration mode from privileged EXEC
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. The prompt for these ports is in the following format:
switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/1
3. Enter the no shutdown command to enable the DCB interface.
switch(conf-if-te-0/1)# no shutdown
