6.2.1.55 set spantree spanguard
Use this command to enable or disable the Spanning Tree span guard function. 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 Section 6.2.2.20). This port will remain disabled until the amount of time defined
by the set spantree spanguardtimeout (Section 6.2.1.58) has passed since the last seen BPDU or
the port is manually unlocked (as described in Section 6.2.1.61).
