Usually, Spanning TreeProtocol (STP) is used to implement link redundancy backup in the network. However, STP is notsuitable for users with a high demand for convergence time. Smart Link can achieve active/standby linkredundancy backup and fast convergence to meet the user demand.Smart Link has the following features:z Active/standby backup for dual-uplink networkingz Simple configuration and operationBasic Concepts in Smart LinkSmart link groupA smart link group consists of two member ports, one master port and one slave port. Normally, only oneport (master or slave) is active, and the other port is blocked, that is, in the standby state. When linkfailure occurs on the port in active state, the smart link group will block the port automatically and turnstandby state to active state on the blocked port.Figure 1-1 Network diagram of Smart LinkIn Figure 1-1, GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 on Switch A are two member ports of asmart link group.
