Syntax

content_copy zoom_out_map
show spanning-tree stp-buffer see-all
<stp-instance stp-instance-id routing-instance instance-name> 
<vlan vlan-id routing-instance instance-name>

Description

Display the configured STP (RSTP, MSTP, VSTP) interface parameters.

Options

none	Display STP (RSTP, MSTP, VSTP) interface role/state changes that are logged into internal memory called the buffer. Entries in the buffer depend on the user configuration.
`stp-instance` `stp-instance-id` `routing-instance` `instance-name`	(Optional) Display the STP buffer for the specified stp-instance and routing instance.
`vlan` `vlan-id` `routing-instance` `instance-name`	(Optional) Display the STP buffer for the specified vlan id and routing instance.

Required Privilege Level

Output Fields

Table 1 describes the output fields for the show spanning-tree stp-buffer see-all command. Output fields are listed in the approximate order in which they appear.

Table 1: show spanning-tree stp-buffer see-all Output Fields
Field Name	Field Description	Level of Output
`Global Events`	Displays events when PPMD RX/TX queues reach 70 % of their maximum queue size. The following indicates received queue status: GT — Greater than 70 % of their maximum queue size. LT — Less than 70 % of their maximum queue size.	none, `stp-instance`, `vlan`
`Per STP instance Information`	Information about every STP instance.	none, `stp-instance`, `vlan`
`Routing Inst`	Routing instance to which the STP instance belongs.	none, `stp-instance`, `vlan`
`STP Instance`	Instance number that uniquely identifies each STP session per routing-instance.	none, `stp-instance`
`Root Bridge`	Bridge priority and bridge ID of ROOT bridge in the topology.	none, `vlan`
`Root Port`	Information about ROOT port, if any, on the local bridge at the displayed timestamp.	none, `vlan`
`TC Received`	Time at which topology change was received and on which port.	none, `stp-instance`, `vlan`
`TC Generated`	Time at which topology change occurred and on which port.	none, `stp-instance`, `vlan`
`Port`	The interface where the event is occurring.	none, `stp-instance`, `vlan`
`State`	STP state of the port. The following are the types of state: Forwarding — Port forwards the traffic and is included in active topology and learns MAC addresses. Blocking — Port does not forward traffic and is not included in active topology. Does not learn MAC addresses.	none, `vlan`
`Role`	Role of the port. The following are the types of ports: Root — Port closest to the Root bridge. Designated — Port sends the best BPDU on the connected segment. Alternate — Port blocked for receiving more useful BPDUs from another bridge. Disabled — Port is disabled. Cannot send or receive BPDUs.	none, `stp-instance`, `vlan`
