show spantree conflicts

Use the show spantree conflicts command to display the MAC address of the root switch in the instance, the time remaining before the VLAN joins the instance, and the number of seconds left before the entry expires and is deleted from the table.

show spantree conflicts vlan
Syntax Description

vlan

Variable that specifies the number of the VLAN.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

This command is available in MISTP or MISTP/PVST+ mode only.

When only one entry is printed (or when all the entries are associated to the same instance), the VLAN is mapped to that instance. If two or more entries are associated with different instances, then the VLAN has a conflict, is blocked, and is not mapped to any instance.

The time left timers associated with the mapping of a VLAN to a MISTP instance are started with the max age of the BPDU, and can be up to the maximum max age. The delay field can show "inactive" to indicate the MAC address is the same as the MAC address of the switch (for example, the switch is the root). In all the other cases, the entry is a number, and the timer restarts every time an incoming BPDU confirms the mapping.

The delay timer field can display:

•Number in seconds that represents the timer running; this timer can be up to the maximum forward delay. The timer is initialized with the fwd delay.

•If the timer is not running, "inactive" is displayed. This is displayed because the VLAN is already mapped to the instance or a conflict exists.

Examples

This example shows the output if there are no conflicts on VLAN 1:
Console> (enable) show spantree conflicts 1

Field

Description

BPDU-related parameters

port spanning tree

Status of whether Spanning Tree Protocol is enabled or disabled on the port.

state

Spanning tree port state (Disabled, Listening, Learning, Forwarding, or Blocking).

port_id

Port identifier of the associated port.

port number

Port number.

path cost

Contribution of the path through this root port. This applies to the total path cost to the root for this bridge.

message age (port/VLAN)

Age of the received protocol information recorded for a port and the value of the Max Age parameter (shown in parenthesis) recorded by the switch.

designated_root

MAC address of the designated spanningtree root bridge.

designated_cost

Cost of the path to the root offered by the designated port on the LAN to which this port is attached.

designated_bridge

Bridge identifier of the bridge assumed to be the Designated Bridge for the LAN associated with the port.

designated_port

Port identifier of the Bridge Port assumed to be the Designated Port for the LAN associated with the port.

top_change_ack

Value of the Topology Change Acknowledgment flag in the next configured BPDU to be transmitted on the associated port. The flag is set in reply to a Topology Change Notification BPDU.

config_pending

Boolean parameter set to record that a configured BPDU should be transmitted on expiration of the hold timer for the associated port.

port_inconsistency

Status of whether the port is in an inconsistent (PVID or port type) state or not.

PORT-based information and statistics

config bpdu's xmitted (port/VLAN)

Number of BPDUs transmitted from the port. The number in parentheses is the number of configured BPDUs transmitted by the switch for this instance of spanning tree.

config bpdu's received (port/VLAN)

Number of BPDUs received by this port. The number in parentheses is the number of configured BPDUs received by the switch for this instance of spanning tree.

tcn bpdu's xmitted (port/VLAN)

Number of TCN BDPUs transmitted on this port.

tcn bpdu's received (port/VLAN)

Number of TCN BPDUs received on this port.

forward trans count

Number of times the port state transitioned to FORWARDing state.

scp failure count

Number of SCP failures.

Status of Port Timers

forward delay timer

Status of the forward delay timer. This timer monitors the time spent by a port in the Listening and Learning States.

forward delay timer value

Current value of the forward delay timer.

message age timer

Status of the message age timer. This timer measures the age of the received protocol information recorded for a port.

message age timer value

Current value of the message age timer.

topology change timer

Status of the topology change timer. This timer determines the time period in which configured BPDUs are transmitted with the topology change flag set by the bridge when it is root following the detection of a topology change.

topology change timer value

Current value of the topology change timer.

hold timer

Status of the hold timer. This timer ensures that configured BPDUs are not transmitted too frequently through any bridge port.

hold timer value

Current value of the hold timer.

delay root port timer

Status of the delay root port timer. This timer enables fast convergence on linkup when the UplinkFast feature is enabled.

delay root port timer value

Current value of the delay root port timer.

VLAN-based information and statistics

spanningtree type

Type of spanning tree (IEEE, IBM, CISCO).

spanningtree multicast address

Destination address used to send out configured BPDUs on a bridge port.

bridge priority

Part of the bridge identifier and is taken as the most significant part bridge ID comparisons.

bridge mac address

Number of the port that caused the topology change.

topology change

Number of times configured BPDUs have been transmitted by the bridge on the LANs for which the bridge is the designated bridge.

topology change time

Time period for which BPDUs are transmitted with the topology change flag set by the bridge when it is the root following the detection of a topology change. It is equal to the sum of the bridge's Max Age and Forward Delay parameters.

topology change detected

Number of topology changes that have been detected by or notified to the bridge.

Number of reported port BPDU counts.

msg age expiry count

Number of message age expires.

link loading

Status of whether the link is oversubscribed.

bpdu in processing

Status of whether the BPDU is under processing.

num of similar bpdus to process

Number of similar BPDUs to process that are received on a specific port.

received_inferior_bpdu

Status of whether the port received an inferior BPDU or in response to an RLQ BPDU.

next state

Port state before it is actually set by spanning tree, to facilitate other tasks in using the new value.

src mac count:

Number of BPDUs with the same source MAC address.

total src mac count

Number of BPDUs with all the source MAC addresses.

curr_src_mac

Source MAC address of the configured BPDU received on a particular port.

next_src_mac

MAC address from the different source.

channel_src_mac

Source MAC address of the channel port. It is used to detect channel misconfiguration and avoid spanning tree loops.

channel src count

Number of times channel_src_mac gets changed and if the limit is exceeded, a channel misconfiguration is detected.

channel ok count

Boolean flag which records the channel status.

show tech-support

Use the show tech-support command to display system and configuration information that you can provide to the Cisco Technical Assistance Center (TAC) when reporting a problem.

show tech-support [{module mod} | {port mod/port}] [vlan vlan] [mistp-instance instance]
[mst instance] [memory] [config]
Syntax Description

module mod

(Optional) Keyword and variable that displays the module number of the switch port.

port mod/port

(Optional) Keyword and variable that specify the module number and port number of the switch port.

vlan vlan

(Optional) Keyword and variable that specify the VLAN; valid values are from 1 to 1001 and from 1025 to 4094.

mistp-instance instance

(Optional) Keyword and variable that specify the MISTP instance number; valid values are from 1 to 16.

mst instance

(Optional) Keyword and variable that specify the MST instance number; valid values are from 0 to 15.

(Optional) Keyword that displays switch configuration.

Defaults

By default, this command displays the output for technical-support-related show commands. Use keywords to specify the type of information to be displayed. If you do not specify any parameters, the system displays the time, as well as all configuration, memory, module, port, instance, and VLAN data.

Command Types

Switch command.

Command Modes

Normal.

Caution Avoid running multiple show tech-support commands on a switch or multiple switches on the network segment. Doing so may cause spanning tree instability.

Usage Guidelines

The show tech-support command output is continuous; it does not display one screen at a time. To interrupt the output, press Ctrl-C.

The show tech-support command may time out if the configuration file output takes longer to display than the configured session timeout time. If this happens, enter a set logout timeout value of 0 to disable automatic disconnection of idle sessions or enter a longer timeout value.

The show tech-support command output is continuous; it does not display one screen at a time. To interrupt the output, press Ctrl-C.

If you specify the config keyword, the show tech-support command displays the output of these commands:

•show config

•show flash

•show log

•show microcode

•show module

•show port

•show spantree active

•show system

•show test

•show trunk

•show version

•show vlan

Note If MISTP is running, the output from the show spantree mistp-instance active and show spantree summary mistp-instance commands are displayed instead of the output from the show spantree active and show spantree summary commands.

Note If MST is running, the output from the show spantree mst and show spantree summary mst commands are displayed instead of the output from the show spantree active and show spantree summary commands.

If you specify the memory keyword, the show tech-support command displays the output of these commands:

•ps

•ps -c

•show cam static

•show cam system

•show flash

•show memory buffers

•show microcode

•show module

•show proc

•show proc mem

•show proc cpu

•show system

•show spantree active

•show version

If you specify a module, port, or VLAN number, the system displays general system information and information for the component you specified.
