1.6 Configuring Guard Functions
1.6.1 Introduction
The following guard functions are available on an MSTP-enabled switch: BPDU guard,
root guard, loop guard, TC-BPDU attack guard, and BPDU drop.
I. BPDU guard
Normally, the access ports of the devices operating on the access layer are directly
connected to terminals (such as PCs) or file servers. These ports are usually
configured as edge ports to achieve rapid transition. But they resume non-edge ports
automatically upon receiving configuration BPDUs, which causes spanning tree
recalculation and network topology jitter.
