Parameter
interface interface_list: Specifies the Ethernet port list, including multiple
Ethernet ports. Expressed as
interface _list={ { interface_type
interface_num | interface_name } [ to { interface_type interface_num
| interface_name } ] }&<1-10>
.
For details about interface_type, interface_num and interface_name, refer
to the
port command in this guide.
&<1-10>: Indicates the preceding parameter can be input up to 10 times.

Related command: reset stp.
Example
To display the RSTP status information for Ethernet1/0/2, enter the following:
<4500>display stp interface Ethernet1/0/2
