More Information About FastLink on Managed PowerConnect Switches

Spanning Tree Protocol (STP) was developed to prevent multiple open paths to the same switch (loops). The Spanning Tree Algorithm (STA) is used to calculate a loop-free network topology.

In some cases, it may be necessary to set certain ports to Fastlink. Fastlink disables spanning tree for that port only (as disabling Spanning Tree for the entire switch is generally not desirable). This is typically used to resolve timeout issues with DHCP clients that boot fast. Spanning Tree has a 30-second timeout period in which the port is set to blocking mode until the algorithm can ascertain if there are loops. When a DHCP client boots up while the port is still in blocking mode, the port can prevent the client from obtaining an IP address.
