Command Mode Global configuration mode Usage Guidelines None Example Switch_config#backup-link-group 1 Switch_config# Related Command None 1.1.2 backup-link-group id preemption-mode forced {delay value} Syntax To set the port-based preemption mode for the backuplink group, run this command. backup-link-group id preemption-mode forced {delay value} To delete the port-based preemption mode for the backuplink group, run the following command: no backup-link-group id 1 Backuplink Configuration Commands Parameters Parameters Description Id Stands for the instance ID of the backuplink group. value Stands for the delay time. Default Value The backuplink group has not been set with the trait of port-based preemption by default. Command Mode Global configuration mode Usage Guidelines The command backup-link-group id preemption-mode forced {delay value} can be used to create BackupLink group directly.

Default Value The MonitorLink group is not configured by default. Command Mode This command is run in global configuration mode. Usage Guidelines None Example Switch _config# monitor-link-group 1 Switch_config# Related Command None 1.2 Port Configuration Commands 1.2.1 backup-link-group id active 3 Backuplink Configuration Commands Syntax To set a port to be an active port, run the following command: backup-link-group id active To cancel the primary port configuration of a port, run the following command: no backup-link-group id Parameters Parameters Description Id Stands for the instance ID of the backuplink group. Default Value The primary port is not configured by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines If the backuplink group is not established, it will be automatically created when you configure the backuplink group on a port directly. Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1#backup-link-group 1 active Switch_config_g0/1#exit Related Command backup-link-group id backup-link-group id backup 1.2.2 backup-link-group id backup Syntax To set a port to be a backup port, run the following command: backup-link-group id backup To cancel the edge port configuration of a port, run the following command: no backup-link-group id Parameters Parameters Description Id Stands for the instance ID of the backuplink group. 4 Backuplink Configuration Commands Default Value The backup port is not configured by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines If the backuplink group is not established, it will be automatically created when you configure the backuplink group on a port directly. Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1#backup-link-group 1 backup Switch_config_g0/1#exit Related Command backup-link-group id backup-link-group id active 1.2.3 share-load vlan vlanmap Syntax To set VLAN load balance for the backup port, run the following command: share-load vlan vlanmap To delete VLAN load balance for the backup port, run the following command: no share-load vlan Parameters Parameters Description vlanmap Stands for the VLAN value. Default Value VLAN load balance is not set for the backup port by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines This command can be set only on the backup port, that is, a port must be set to be a backup port before VLAN load balance is set on the port. 5 Backuplink Configuration Commands For different BackupLink groups, the same group VLAN can be configured, or they have overlapping VLAN segments. If there are overlapped VLAN segments, the system will classify these VLANs into different MSTs (STGs) and conduct operations toward a group of ports, the statuses of these ports in different MSTs vary. So, typically, when the load balancing VLAN group is configured, it is better to select the VLAN group without overlapping. Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1# share-load vlan 100-200 Switch_config_g0/1#exit Related Command backup-link-group id backup-link-group id backup 1.2.4 backup-link-group mmu transmit Syntax To set MMU transmission for the ports of the backuplink group, run the following command: backup-link-group mmu transmit To delete MMU transmission for the ports of the backuplink group, run the following command: no backup-link-group mmu Parameters None Default Value The MMU transmission function for the ports of the backuplink group is not set by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines Only the ports of the backuplink group can be set to transmit, that is, the ports must be set to active or backup. Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1#backup-link-group mmu transmit Switch_config_g0/1#exit 6 Backuplink Configuration Commands Related Command backup-link-group id 1.2.5 backup-link-group mmu receive Syntax To set MMU reception for ports, run the following command: backup-link-group mmu receive To delete MMU reception for ports, run the following command: no backup-link-group mmu Parameters None Default Value The MMU reception function for the ports is not set by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines The ports that are set to receive are not necessarily the ports of the backuplink group. Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1#backup-link-group mmu receive Switch_config_g0/1#exit Related Command None 1.2.6 monitor-link-group id uplink Syntax To set a port to be an uplink port, run the following command: monitor-link-group id uplink To cancel the uplink port configuration, run the following command: no monitor-link-group id Parameters Parameters Description 7 Backuplink Configuration Commands Id Stands for the instance ID of the monitorlink group. Default Value The uplink port is not configured by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines If the MonitorLink group port role is directly configured for the port in the case that the MonitorLink group is not established, the system will automatically create the MonitorLink group . Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1# monitor-link-group 1 uplink Switch_config_g0/1#exit Related Command monitor-link-group id monitor-link-group id downlink 1.2.7 monitor-link-group id downlink Syntax To set a port to be a downlink port, run the following command: monitor-link-group id downlink To cancel the downlink port configuration, run the following command: no monitor-link-group id Parameters Parameters Description Id Stands for the instance ID of the monitorlink group. Default Value The downlink port is not configured by default. Command Mode The physical port configuration mode and the converged port configuration mode Usage Guidelines If the MonitorLink group port role is directly configured for the port in the case that the MonitorLink 8 Backuplink Configuration Commands group is not established, the system will automatically create the MonitorLink group . Example Switch_config#interface gigaEthernet 0/1 Switch_config_g0/1# monitor-link-group 1 downlink Switch_config_g0/1#exit Related Command monitor-link-group id monitor-link-group id uplink 1.3 Show 1.3.1 show backup-link-group id Syntax To display the information about the backuplink group, run the following command: show backup-link-group id Parameters Parameters Description Id Stands for the instance ID of the backuplink group. Default Value None Command Mode Monitoring mode, global configuration mode, node configuration mode or port configuration mode Usage Guidelines None Example Switch_config# show backup-link-group 1 Active Interface Backup Interface State Vlan State ------------------------------------------------------------------------------ GigaEthernet0/2 GigaEthernet0/4 Forward/Block Block/Block Share load vlan: 100-200,port[GigaEthernet0/4] vlan state: Forwarding Preemption Mode: No Preempt 9 Backuplink Configuration Commands Preemption Delay: 0 seconds Related Command None 1.3.2 show monitor-link-group id Syntax To configure the instance ID of the monitorlink group, run the following command. show monitor-link-group id Parameters Parameters Description Id Stands for the instance ID of the monitorlink group. Default Value None Command Mode Monitoring mode, global configuration mode, node configuration mode or port configuration mode Usage Guidelines None Example Switch_config#show monitor-link-group 1 uplink interface: GigaEthernet0/2 Forwarding downlink interface: GigaEthernet0/1 Forwarding GigaEthernet0/3 Forwarding Related Command None 10
