Symbol MIB for MSTP

Specifies the maximum allowed hops for a BPDU in an MST region. This parameter is used by all the instances of the MST.

An indication of wheter the Bridge supports Spanning Tree Protocol. The bit nonStp(0) indicates, the Bridge doesn't support any Spanning Tree Protocol. The bit 'dot1d1998(1)' indicates the Spanning Tree Protocol specified in EEE 802.1D-1998, 'dot1w(2)' indicates the Rapid Spanning Tree Protocol specified in IEEE Std 802.1w, 'dot1d2004' indicates IEEE Std 802.1D-2004 and 'dot1s(4) means MSTP IEEE Std 802.1s. When the bridge supprts a non-listed version, the bit unknown(15) should be set. Bits: 'dot1w': 2, 'reserved14': 14, 'dot1s': 4, 'reserved10': 10, 'dot1q': 5, 'reserved12': 12, 'reserved13': 13, 'unknown': 15, 'dot1d2004': 3, 'reserved7': 7, 'reserved9': 9, 'reserved8': 8, 'reserved11': 11, 'nonStp': 0, 'reserved6': 6, 'dot1d1998': 1.

This object is relevant if the Bridges that can supply a number of versions of STP. For GET operation this object reflects the mode in which the Bridge works currently. If the Bridge works currently in the version, not listed here, the value unknown(4) must be returned. For SET operation the value unknown(15) must be rejected. Another value may be rejected too if the Bridge does not support correspond mode (see wsSwMstpVersionsSupported). The value forceNonStp(0) indicates, the Spanning Tree Protocol is disabled on the Bridge (or the Spanning Tree Protocol Emulation operates). Other possible values are described in IEEE Std 802.1s clause 12.8.1.3.e) Enumeration: 'forceDot1w': 2, 'unknown': 15, 'forceLegacyDot1d': 1, 'autoDot1s': 3, 'forceNonStp': 0.

Configuration Identificator Format Selector.

The configuration name that identifies the MST region and is used as one of the inputs in the computation of the MST Configuration Identifier.

This object identifies the MST revision that identifies the MST region and is used as one of the inputs in the computation of the MST configuration Identifier.

The computed Configuration Digest.

Regional root of the CIST.

External root cost of CIST.

The BPDU guard feature shuts down the port on receiving a BPDU on a BPDU-guard enabled port. This object associates a timer with the feature such that the port gets enabled back without manual intervention after a set interval. This interval can be configured by the user using object wsSwMstpErrdisableTimeoutInterval

Specifies the time interval in seconds after which a port for which wsSwMstpErrdisableTimeout is true, is brought back up.

Enabling the BPDU Filter feature ensures that PortFastenabled ports (edge ports for which dot1dStpPortOperEdgePort is true) do not transmit or receive any BPDUs

When the BPDU Guard feature is set for a bridge, all portfast-enabled ports (edge ports for which dot1dStpPortOperEdgePort is true) of the bridge that have bpdu-guard set to default shut down the port on receiving a BPDU. In this case, the BPDU is not processed.

Enabled interoperability with Cisco's version of MSTP

The operational value of the Cisco interoperability parameter. True if Cisco interoperability is administratively enabled and a Cisco BPDU is detected.

The global state of MSTP in the switch. The possible states are enabled, disabled and disabledWithBridgeForward Enumeration: 'disabled': 2, 'enabled': 1.

This table contains one entry for each instance of MSTP.

A conceptual row containing the status of the MSTP instance.

Uniquely identifies an instance. The entry of this table with index 0 presents always, represents CIST. However, a SET operation at the CIST index returns an error.

A string of octets containing one bit per VLAN. The first octet corresponds to VLANs with VlanIndex values 1 through 8; the second octet to VLANs 9 through 16 etc. The most significant bit of each octet corresponds to the lowest VlanIndex value in that octet. For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'. Empty (zero) most significant octes are not mandatory.

A string of octets containing one bit per VLAN for VLANS with VlanIndex values 1024 through 2047. The first octet corresponds to VLANs with VlanIndex values 1024 through 1031; the second octet to VLANs 1032 through 1039 etc. The most significant bit of each octet corresponds to the lowest VlanIndex value in that octet. For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'. Empty (zero) most significant octes are not mandatory.

A string of octets containing one bit per VLAN for VLANS with VlanIndex values 2048 through 3071. The first octet corresponds to VLANs with VlanIndex values of 2048 through 2055; the second octet to VLANs 2056 through 2063 etc. The most significant bit of each octet corresponds to the lowest VlanIndex value in that octet. For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'. Empty (zero) most significant octes are not mandatory.

A string of octets containing one bit per VLAN for VLANS with VlanIndex values 3072 through 4095. The first octet corresponds to VLANs with VlanIndex values 3072 through 3079; the second octet to VLANs 3080 through 3087 etc. The most significant bit of each octet corresponds to the lowest VlanIndex value in that octet. For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'. Empty (zero) most significant octes are not mandatory.

This table contains one entry for each VlanId.

Information regarding the instance to which each Vlan is mapped.

The VlanId for which this entry contains the instance mapped.

An integer with values ranging from 0 to 16 that identify the CIST/MSTI instance to which this VLAN is mapped

A table that contains generic information about every port that is associated with this bridge.

A list of information for each port of the bridge.

A unique value, greater than zero, for each Port. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re- initialization.

The value of the MAC Enabled parameter (6.4.2 of IEEE Std 802.1D, 1998 Edition). May be present if the implementation supports the MAC Enabled parameter.

The operational value of the MAC Enabled parameter (6.4.2 of IEEE Std 802.1D, 1998 Edition). May be present if the implementation supports the MAC Enabled parameter.

Optional and provided only by MSTP Bridges that support the automatic identification of edge ports.

The designated bridge for this port

If set to true, makes sure that the port on which it is enabled is a designated port. If the Root Guard enabled port receives a superior BPDU, it goes to a discarding state.

Enabling the Port BPDU Filter feature ensures that PortFastenabled ports (edge ports for which dot1dStpPortOperEdgePort is true) do not transmit or receive any BPDUs. When set to enabled or disabled, this configuration takes precedence over wsSwMstpPortfastBpduFilter. However, when setto default, the bridge level BPDU-filter configuration takes effect for the port. Enumeration: 'disabled': 1, 'default': 2, 'enabled': 0.

The operational value for Portfast BPDU Filter for this port

When the BPDU Guard feature is set for a bridge, all portfast-enabled ports (edge ports for which dot1dStpPortOperEdgePort is true) of the bridge that have bpdu-guard set to default shut down the port on receiving a BPDU. In this case, the BPDU is not processed. When set to enabled or disabled, this configuration takes precedence over wsSwMstpPortfastBpduGuard. However, when setto default, the bridge level BPDU-guard configuration takes effect for the port. Enumeration: 'disabled': 1, 'default': 2, 'enabled': 0.
