Enter system view
Perform the mCheck
operation
II. Perform the mCheck operation in Ethernet port view
Follow these steps to perform the mCheck operation in Ethernet port view:
Enter system view
Enter Ethernet port view
Perform the mCheck
operation

1.5.3 Configuration Example

# Perform the mCheck operation on Ethernet 1/0/1.
1) Perform this configuration in system view
<Sysname> system-view
[Sysname] stp interface Ethernet 1/0/1 mcheck
2) Perform this configuration in Ethernet port view
<Sysname> system-view
[Sysname] interface Ethernet 1/0/1
[Sysname-Ethernet1/0/1] stp mcheck

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.
