10.Spanning Tree Protocol Configuration

The Spanning Tree Algorithm can be used to detect and disable network loops,

and to provide backup links between switches, bridges or routers. This allows the

switch  to  interact  with  other  bridging  devices  (that  is,  an  STA-compliant  switch,

bridge  or  router)  in  your  network  to  ensure  that  only  one  route  exists  between

any  two  stations  on  the  network,  and  provide  backup  links  which  automatically

take over when a primary link goes down.

Managing Global Settings

Global settings apply to the entire switch.

Command Attributes

The following global attributes are fixed and cannot be changed:

> Bridge ID – The priority and MAC address of this device.

>  Designated  Root –  The  priority  and  MAC  address  of  the  device  in  the

Spanning Tree that this switch has accepted as the root device.

> Root Port – The number of the port on this switch that is closest to the root.

This switch communicates with the root device through this port. If there is no

root  port,  then  this  switch  has  been  accepted  as  the  root  device  of  the

Spanning Tree network.

>  Root  Path  Cost  –  The  path  cost  from  the  root  port  on  this  switch  to  the  root

device.

> Configuration Changes – The number of times the Spanning Tree has been

reconfigured.

> Last Topology Change – The time since the Spanning Tree was last reconfig-

ured.

The following global attributes can be configured:
