322 CHAPTER 10: USING RSTP COMMANDS RSTP Configuration Commands This section describes how to use the Rapid Spanning Tree Protocol (RSTP) configuration commands on your Switch. display stp Syntax display stp [ interface interface_list ] display stp brief View Any view 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 } ] }&. For details about interface_type, interface_num and interface_name, refer to the port command in this manual. &: Indicates the preceding parameter can be input up to 10 times. Description Use the display stp command to view the status information of the current RSTP. Use the display stp brief command to view summary information of the STP state of the Switch. Related command: reset stp. Example To display the RSTP status information for GigabitEthernet1/0/2, enter the following: display stp interface GigabitEthernet1/0/2 Protocol mode: IEEE RSTP The bridge ID (Pri.MAC): 32768.00e0-fc00-5600 The bridge times: Hello Time 2 sec, Max Age 20 sec, Forward Delay 15 sec Root bridge ID(Pri.MAC): 32768.00e0-fc00-5600 Root path cost: 0 Bridge bpdu-protection: disabled Default path cost standard is dot1t Timeout factor: 3 Port 2 (Ethernet1/0/2) of bridge is DOWN Port spanning tree protocol: enabled Port role: Disabled Port Port path cost: 2000000 Port priority: 128 Designated bridge ID(Pri.MAC): 32768.00e0-fc00-5600 The Port is a non-edged port Connected to a non-point-to-point LAN segment
