Message Type: DCE
Severity: ERROR
Probable Cause: Indicates that the system has failed to allocate memory.
Recommended Action: Check the memory usage on the switch using the show process memory command.
Reload or power cycle the switch.
Message: <message>: <message>.
Message Type: DCE
Severity: ERROR
Probable Cause: Indicates that the system has failed to initialize.
Recommended Action: Reload or power cycle the switch.
Message: <message>: <message>.
Message Type: DCE
Severity: ERROR
Probable Cause: Indicates a connection, transfer, or receiving error in the socket.
Recommended Action: If this is a modular switch, execute the ha failover command. If the problem persists or if this is a compact switch, download a new firmware version using the firmware download command.
Message: Received BPDU on PortFast enable port. Shutting down Interface <message>
Message Type: DCE
Severity: ERROR
Probable Cause: Indicates that a port on which PortFast is enabled has received a bridge protocol data unit (BPDU). The port has been disabled.
Recommended Action: Disable the PortFast feature on the port using one of the following commands:
• For Rapid Spanning Tree Protocol (RSTP), execute the no spanning-tree edgeport command.
• For Spanning Tree Protocol (STP), execute the no spanning-tree portfast command.
After disabling the PortFast feature, execute the no shutdown command to re-enable the port.
Message: <message>.
Message Type: DCE
Severity: INFO
Probable Cause: Indicates that the Multiple Spanning Tree Protocol (MSTP) bridge mode has changed.
Recommended Action: No action is required.
Message: <Bridge mode information>. My Bridge ID: <Bridge ID> Old Root: <Old Root ID> New Root: <New Root ID>.
Message Type: DCE
Severity: INFO
Probable Cause:Indicates that the Multiple Spanning Tree Protocol (MSTP) bridge or bridge instance root has been changed.
Recommended Action: No action is required.
Message: MSTP instance <instance> is created.
Message Type: DCE
Severity: INFO
Probable Cause: Indicates that the specified Multiple Spanning Tree Protocol (MSTP) instance has been created.
Recommended Action: No action is required.
Message: MSTP instance <instance> is deleted.
Message Type: DCE
Severity: INFO
Probable Cause:Indicates that the specified Multiple Spanning Tree Protocol (MSTP) instance has been deleted.
Recommended Action: No action is required.
Message: VLAN <vlan_ids> is <action> on MSTP instance <instance>.
Message Type: DCE
Severity: INFO
Probable Cause:Indicates that the specified Multiple Spanning Tree Protocol (MSTP) instance has been modified.
Recommended Action: No action is required.
Message: MSTP instance <instance> bridge priority is changed from <priority_old> to <priority_new>.
Message Type: DCE
Severity: INFO
Probable Cause:Indicates that the specified Multiple Spanning Tree Protocol (MSTP) instance priority has been modified.
Recommended Action: No action is required.
Message: <Bridge mode information>: <vlan/instance and port> - STP state <state>
Message Type: DCE
Severity: INFO
Probable Cause:Indicates that the STP port state has been changed.
Recommended Action: No action is required.
Message: Could not restore spanning tree protocol settings from startup-config. Spanning tree is configured in shutdown state.
Message Type: DCE
Severity:ERROR
Probable Cause: Indicates that allocation of logical bridge ID has failed. The VCS cluster formation could be in progress.
Recommended Action: Wait for cluster formation to complete and then enable the Spanning Tree Protocol using the no spanning-tree shutdown command. You may have to execute the shutdown command followed by the no shutdown command from protocol spanning-tree submode.
Message: Could not restore spanning tree state for interface <ifName>.
Message Type: DCE
Severity:ERROR
Probable Cause: Indicates that allocation of logical port ID has failed. The VCS cluster formation could be in progress.
Recommended Action:Wait for cluster formation to complete and then enable the spanning tree on the interface. You may have to execute the spanning-tree shutdown command followed by the no spanning-tree shutdown command from interface submode.
Message: Could not restore spanning tree state for interface <ifName>. Maximum port count reached.
Message Type: DCE
Severity:ERROR
Probable Cause: Indicates that the system ran out of port ID space, probably due to stale entries in the system. The maximum port count for STP and PVST is 1 through 255, and for RSTP, MSTP, and RPVST the maximum port count is 1 through 4095.
Recommended Action: Shut down spanning tree on interfaces that are no longer required using the spanning-tree shutdown command and try the operation again.
