The vlan-id argument ranges from 1 to 4094.DescriptionUse the flush enable command to enable flush update.Use the undo flush enable command to disable flush update.By default, flush update is enabled for smart link groups and VLAN 1 is used for flush message transmission.Note that, you need to configure different control VLANs for different smart link groups.Related commands: smart-link flush enable.Examples# Enable flush update for smart link group 1.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1] flush enableportSyntaxport interface-type interface-number { master | slave }undo port interface-type interface-numberViewSmart link group viewDefault Level2: System levelParametersinterface-type interface-number: Port type and port number. This must be an Ethernet port.master: Specifies a port as the master port.slave: Specifies a port as the slave port.DescriptionUse the port command to assign the specified port as the master or slave port of the current smart link group.Use the undo port command to remove the specified port from the smart link group.Note that:z Disable STP and RRPP on the ports you want to add to the smart link group, and make sure that the ports are not member ports of any aggregation group or service loopback group. On the otherhand, you cannot enable STP or RRPP on a smart link group member port or assign a smart linkgroup member port to an aggregation group or service loopback group.z You can assign a port to a smart link group with the port smart-link group command in Ethernet port view.Related commands: port smart-link group.Examples# Configure GigabitEthernet1/1/1 as the slave port of smart link group 1.<Sysname> system-view[Sysname] interface gigabitethernet 1/1/1[Sysname-GigabitEthernet1/1/1] undo stp enable[Sysname-GigabitEthernet1/1/1] quit[Sysname] smart-link group 1[Sysname-smlk-group1] protected-vlan reference-instance 0[Sysname-smlk-group1] port gigabitethernet 1/1/1 slaveport smart-link groupSyntaxport smart-link group group-id{ master | slave }undo port smart-link group group-idViewEthernet port viewDefault Level2: System levelgroup-id: Smart link group ID, in the range of 1 to 6.master: Specifies the port as the master port.slave: Specifies the port as the slave port.DescriptionUse the port smart-link group command to configure the current port as a member of the specified smart link group.Use the port smart-link group command to remove the port from the specified smart link group.Note that:z Disable STP and RRPP on the ports you want to add to the smart link group, and make sure that the ports are not member ports of any aggregation group or service loopback group. On the otherhand, you cannot enable STP or RRPP on a smart link group member port or assign a smart linkgroup member port to an aggregation group or service loopback group.z You can assign a port to a smart link group with the port command in smart link group view.Related commands: port.Examples# Configure GigabitEthernet1/1/1 as the master port of smart link group 1.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1] protected-vlan reference-instance 0[Sysname-smlk-group1] quit[Sysname] interface gigabitethernet 1/1/1[Sysname-GigabitEthernet1/1/1] undo stp enable[Sysname-GigabitEthernet1/1/1] port smart-link group 1 masterpreemption delaySyntaxpreemption delay delay-timeundo preemption delayViewSmart link group viewDefault Level2: System levelParametersdelay-time: Preemption delay (in seconds), in the range of 0 to 300.Use the preemption delay command to set the preemption delay. When role preemption is enabled, after the preemption delay is set, the master port waits for some time before taking over, so as to collaborate with the switchover of upstream devices.Use the undo preemption delay command to restore the default.By default, the preemption delay is 1 second.Note that, the preemption delay configuration takes effect only after role preemption is enabled.Related commands: preemption mode.Examples# Enable role preemption and set the preemption delay to 10 seconds.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1] preemption mode role[Sysname-smlk-group1] preemption delay 10preemption modeSyntaxpreemption mode roleundo preemption modeViewSmart link group viewDefault Level2: System levelParametersrole: Configures the role preemption mode, which enables the master port to preempt the slave port in active state.DescriptionUse the preemption mode command to enable the role preemption mode.Use the undo preemption mode command to restore the default.By default, role preemption is disabled.Examples# Enable the role preemption mode.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1] preemption mode roleprotected-vlanSyntaxprotected-vlan reference-instance instance-id-listundo protected-vlan [ reference-instance instance-id-list]ViewSmart link group viewDefault Level2: System levelParametersreference-instance instance-id-list: Specifies the MSTIs to be referenced in the form of instance-id-list = {instance-id [ to instance-id ] }&<1-10>, where the range of the instance-id argument is as specified in the command configuring MSTIs and &<1-10> indicates that you can provide up to ten MSTIs or MSTI lists.DescriptionUse the protected-vlan command to configure protected VLANs for a smart link group by referencing MSTIs. You can use the display stp region-configuration command to view the VLANs mapped to the referenced MSTIs.Use the undo protected-vlan command to remove the specified protected VLANs from a smart link group by referencing the specified MSTIs. If no MSTI is specified, all the protected VLANs of the smart link group are removed.By default, no protected VLAN is configured for a smart link group.Note that:z Before assigning ports to a smart link group, configure protected VLANs for the smart link group.z You can remove all protected VLANs from a smart link group when the group is empty but not aftera member port is assigned to it.z Removing a smart link group also removes its protected VLANs.z If the VLAN(s) mapped to a referenced MSTI changes, the protected VLAN(s) change accordingly.z The VLANs that the member ports of a smart link group belong to must be configured as the protected VLANs of the smart link group.Related commands: smart-link group, display stp region-configuration in MSTP Commands in this manual.Examples# Configure the VLANs mapped to MSTIs 1 through 10 and MSTI 12 as the protected VLANs of smart link group 1.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1] protected-vlan reference-instance 1 to 10 12reset smart-link statisticsSyntaxreset smart-link statisticsViewUser viewDefault Level2: System levelParametersNoneDescriptionUse the reset smart-link statistics command to clear the statistics about flush messages.Examples# Clear the statistics about flush messages.<Sysname> reset smart-link statisticssmart-link flush enableSyntaxsmart-link flush enable [ control-vlan vlan-id-list]undo smart-link flush enable [ control-vlan vlan-id-list]ViewEthernet port view, OLT port viewDefault Level2: System levelParameterscontrol-vlan vlan-id-list: Specifies the control VLANs used for receiving flush messages. The vlan-id-list is expressed in the form of vlan-id-list = { vlan-id [ to vlan-id ] }&<1-10>, where the vlan-id argument ranges from 1 to 4094 and &<1-10> indicates that you can provide up to ten VLAN IDs or VLAN ID lists.DescriptionUse the smart-link flush enable command to configure a VLAN for receiving flush messages, that is, a receive control VLAN, on a port in Ethernet interface view or on all ports in system view.Use the undo smart-link flush enable command to disable flush message processing.By default, flush messages are not processed.Note that:z If no VLAN is specified, VLAN 1 applies.z This command cannot be used on member port of an aggregation group or service loopback group.Related commands: flush enable.Examples# Enable GigabitEthernet1/1/1 to process the flush messages received in VLAN 1.<Sysname> system-view[Sysname] interface gigabitethernet 1/1/1[Sysname-GigabitEthernet1/1/1] smart-link flush enable# Enable Olt1/0/1 to process the flush messages received in VLAN 1.<Sysname> system-view[Sysname] interface olt 1/0/1[Sysname-Olt1/0/1] smart-link flush enablesmart-link groupSyntaxsmart-link group group-idundo smart-link group group-idViewSystem viewDefault Level2: System levelParametersgroup-id: Smart link group ID, in the range of 1 to 6.DescriptionUse the smart-link group command to create a smart link group and enter smart link group view.Use the undo link-aggregation group command to remove a smart link group.Note that a smart link group with member ports cannot be removed.Examples# Create smart link group 1 and enter smart link group view.<Sysname> system-view[Sysname] smart-link group 1[Sysname-smlk-group1]。
