Deprecated the wwpLeosMstpPvstBpduReceivedNotification mib

The wwpLeosMstpNewRootNotification indicates that the sending agent has become the new root of the Spanning Tree for the specified XST (CIST or MSTI). This notification is generated when the Port Role Selection state machine invokes the updtRolesTree procedure and this procedure operation results in a calculation of a Root Priority Vector for the XST which results in a value indicating that the bridge itself has become the root bridge for the XST.

A wwpLeosMstpTopologyChangeNotification is sent by a bridge for the specified XST when the Topology Change state machine invokes the newTcWhile procedure which causes the tcWhile timer for the specified port and XST to change from a zero value to a non-zero value.

A wwpLeosMstpPortBackupNotification is sent whenever the MSTP state machine logic determines that a loop has occurred and the received vector information represents another port on the same device. This notification is sent when the updtRolesTree procedure determines that the designated bridge and designated port components of the port priority vector reflect another port on this bridge which results in the selectedRole parameter for the CIST to transition to BackupPort.

A wwpLeosMstpPvstBpduReceivedNotification is sent to indicate that one or more PVST BPDUs have been received on the port in the past 60 seconds. Each minute, all ports are checked for reception of one or more PVST BPDUs and this notification is generated if any PVST BPDUs have been received.

A wwpLeosMstpSelfLoopNotification is sent whenever device detects same cable connected to a port in a loop back. This determination is made by comparing the layer-2 address of the received frame with that of the bridge. This occurs before the frame data reaches the MSTP state machine logic. Also if loop-back blocking is enabled on the device then mstp will block this port (self disable).

A wwpLeosMstpPortOperEdgeNotification is sent whenever the MSTP state machine logic causes a change in the operEdge parameter associated with the specified port.

A wwpLeosMstpPortFlapNotification is sent whenever device detects a port flapping. This notification is generated under following criteria. If device detects port flapped more than once within 1 minute timer period and it has not sent notification within last 5 minutes then it will generate this notification.

A wwpLeosMstpBridgeRootPortLostNotification is sent whenever device detects that bridge root port is lost for a particular XST (CIST or MSTI). This notification is generated when a link has gone down and the role parameter for the CIST or any MSTI for that port is set to Root Port. This notification will indicate either the link failure or link partner MSTP disabled.

When this object is set to true the MSTP operation for the bridge is enabled. Setting this object to false disables bridge MSTP operations.

This object contains the value of the ForceVersion MSTP State Machine Performance Parameter. Enumeration: 'mstp': 3, 'stp': 0, 'rstp': 2.

This object represents the value of the FwdDelay MSTP State Machine Performance Parameter.

This object represents the value of the TxHoldCount MSTP State Machine Performance Parameter.

This object represents the value of the HelloTime MSTP State Machine Performance Parameter.

This object represents the value of the Max Age value used by the multiple spanning tree protocol.

This object represents the value of the MaxHops MSTP State Machine Performance Parameter.

This object specifies if loopback port blocking feature is enabled/disabled for the multiple spanning tree protocol. Values of true or false will enable or disable this feature, respectively.

The version of the Spanning Tree default Path Costs that are to be used by this Bridge. A value of 8021d1998(1) uses the 16-bit default Path Costs from IEEE Std. 802.1D-1998. A value of stp8021t2001(2) uses the 32-bit default Path Costs from IEEE Std. 802.1t. Enumeration: 'stp8021d1998': 1, 'stp8021t2001': 2.

For devices that contain multiple STP code-bases, this object allows the selection of the desired Spanning Tree Protocol code-base that is to be in effect. After a new value is selected a configuration save and device reboot must be performed for the new spanning tree code-base to take control over spanning tree operations within the device. The value of rstp(1) selects legacy RSTP code-base which is typically a highly optimized code-base intended for devices which are connected to other RSTP equipped devices. The value of mstp(2) selects the MSTP code-base which offers inherent backward compatibility for RSTP devices however this code-base is optimized for MSTP operations and may not be desirable when the device is operating in a network of only RSTP connected devices. Enumeration: 'mstp': 2, 'rstp': 1.

Table that contains configuration items for each port. This object has value similar to dot1dStpPortTable.

MSTP port information entry containing configuration items specific to a particular port on the Bridge.

This is the port number used as index in the table. The value of this port id is similar to dot1dStpPort.

When this object is set to true the mstp operation for this port is enabled. Setting this object to false disables mstp operations on this port.

The administratively configurable external path cost. This object sets the ExternalPortPathCost MSTP State Machine Performance Parameter when configured to use manual port path cost values. This is used as the CIST External Path Cost field for this port in BPDUs and used in vector calculations for this port. The default value for this object is system dependent.

The current operational external path cost for this port. Depending on the configuration, this may be the administratively configured external path cost or a value calculated by the system.

This attribute enables or disables dynamic calculation of the external path cost for the given port. Values of true or false will enable or disable this feature, respectively.

The administrative value of the Edge Port parameter. A value of true indicates that this port should be assumed as an edge-port and a value of false indicates that this port should be assumed as a non-edge-port. The default value for this object is system dependent.

The operational value of the Edge Port parameter. The object is initialized to the value of wwpLeosMstpPortAdminEdgePort and is set false on reception of a BPDU.

When set to true, this object forces a spanning tree migration check to initiate within the definitions of the spanning tree state machines per IEEE. Any other operation on this object has no effect and it always returns false when read.

The administrative point-to-point status of the LAN segment attached to this port. A value of forceTrue indicates that this port should always be treated as if it is connected to a point-to-point link. A value of forceFalse indicates that this port should be treated as having a shared media connection. A value of auto indicates that this port is considered to have a point-to-point link if it is an Aggregator and all of its members are aggregatable, or if the MAC entity is configured for full duplex operation, either through auto-negotiation or by management means. Enumeration: 'forceFalse': 1, 'forceTrue': 0, 'auto': 2.

The operational point-to-point status of the LAN segment attached to this port. It indicates whether a port is considered to have a point-to-point connection or not. The value is determined by management or by auto-detection, as described in the wwpMtpPortAdminPointToPoint object.

The value of the autoEdge parameter used by MSTP to determine whether the value of wwpLeosMstpPortOperEdgePort should be set to the value of wwpLeosMstpPortAdminEdgePort or if it should be set according to the logic defined in the Bridge Detection state machine.

The value of the restrictedRole parameter used by MSTP. When true, the port will not be selected as the root port for the CIST or any MSTI, even if it has the best spanning tree priority vector. Such a port will be selected as an alternate port after the root port has been selected. When false, this port is allowed to be selected as the root port.

The value of the restrictedTcn parameter used by MSTP. When true, the port will not propagate received topology change notifications and topology changes to other ports. When false, normal topology change notification propagation will occur on the port.

The configuration name that identifies the MST region and is used as one of the inputs in the computation of the MST Configuration Identifier. MSTP uses a fixed field of 32 characters when computing the MST Configuration Identifier and in MSTP BPDUs, when this object is set to a string of characters less than 32 in length, MST will fill in the remaining characters up to character number 32 with NULL octets (hex value 0x00). The default value for this object is the Bridge MAC address represented as an ASCII character string in canonical format, using upper-case hexadecimal letters and hyphens to represent the 48-bit Bridge MAC, with the remaining 15 characters containing the NULL octet (hex value 0x00).

The value of this object is used by MSTP as the Revision Level field transmitted in MSTP BPDUs and in the calculation of the MST Configuration Identifier.
