6.3.14 Clear protocol compatibility mode
[Syntax]
clear spanning-tree detected protocols [interface ifname]
[Keyword]
interface : Specifies the interface to clear
[Parameter]
ifname : Name of LAN/SFP port or logical interface
Interface to clear
[Input mode]
privileged EXEC mode
[Description]
Returns an interface that had been operating in STP compatibility mode to normal mode.
If "interface" is omitted, the status of all interfaces is cleared.
[Note]
If a STP BPDU is received, the interface that received it will operate in STP compatibility mode. However even if STP BPDU
is no longer received subsequently, the corresponding interface continues to operate in STP compatibility mode. In such cases,
you can execute this command to make the interface return from STP compatibility mode to normal mode.
[Example]
Return LAN port #1 from STP compatibility to normal mode.
