Command Reference Guide
clear spanning-tree detected-protocols
Use the clear spanning-tree detected-protocols command to restart the protocol migration process.
Variations of this command include:
clear spanning-tree detected-protocols
clear spanning-tree detected-protocols interface <interface>
Syntax Description
interface <interface>
Default Values
No default values are necessary for this command.
Command History
Release 5.1
Release A4.01
Functional Notes
The switch has the ability to operate using the rapid spanning-tree protocol or the legacy 802.1D version of
spanning-tree. When a bridge protocol data unit (BPDU) of the legacy version is detected on an interface,
the switch automatically regresses to using the 802.1D spanning-tree protocol for that interface. Issue the
clear spanning-tree detected-protocols command to return to rapid spanning-tree operation.
Usage Examples
The following example re-initiates the protocol migration process on Ethernet interface 0/3:
>enable
#clear spanning-tree detected-protocols interface ethernet 0/3
The following example re-initiates the protocol migration process on all interfaces:
>enable
#clear spanning-tree detected-protocols

Optional. Specifies a valid interface to clear. Specify an interface in the
format <interface type [slot/port | slot/port.subinterface id | interface id |
interface id.subinterface id | ap | ap/radio | ap/radio.vap]>. For example, for
a T1 interface, use t1 0/1; for an Ethernet subinterface, use eth 0/1.1; for a
PPP interface, use ppp 1; for an ATM subinterface, use atm 1.1; and for a
wireless virtual access point, use dot11ap 1/1.1. Type clear spanning-tree
detected-protocols interface ? for a complete list of applicable interfaces.
Command was introduced.
Command was expanded to include the Metro Ethernet Forum (MEF)
Ethernet interface.
