clear spanning-tree detected-protocols [interface <interface id>]
Use the clear spanning-tree detected-protocols command to restart the protocol migration process.
Syntax Description
interface <interface id> Optional. Specifies a valid interface to clear. Type clear spanning-tree
detected-protocols interface ? for a complete list of applicable interfaces.
Default Values
No default value necessary for this command.
Applicable Platforms
This command applies to the NetVanta 300, 1000, 1000R, 3000, 4000, and 5000 and Total Access 900
Series units.
Command History
Release 5.1 Command was introduced.
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 BPDU (bridge protocol data unit) 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
