Use this command to enable or disable the Spanning Tree span guard function.

set spantree spanguard { enable | disable }

Usage
When enabled, this prevents an unauthorized bridge from becoming part of the active Spanning
Tree topology. It does this by disabling a port that receives a BPDU when that port has been
defined as an edge (user) port (as described in “ set spantree adminedge ” on page 6 ‐ 60). This port
will remain disabled until the amount of time defined by the set spantree spanguardtimeout (“ set
spantree spanguardtimeout ” on page 6 ‐ 38) has passed since the last seen BPDU or the port is
manually unlocked (as described in “ clear / set spantree spanguardlock ” on page 6 ‐ 39).
enable | disable Enables or disables the span guard function.
