The Bridge MIB module for managing devices that support IEEE Std 802.1Q. This MIB module is derived from the IETF BRIDGE-MIB, RFC 4188. Unless otherwise indicated, the references in this MIB module are to IEEE Std 802.1Q-2014. Copyright (C) IEEE (2014). This version of this MIB module is part of IEEE802.1Q; see the draft itself for full legal notices.

A table that contains generic information about every Bridge component. All writable objects in this table MUST be persistent over power up restart/reboot.

A list of objects containing information for each Bridge component.

The component identifier is used to distinguish between the multiple virtual Bridge instances within a PBB. In simple situations where there is only a single component the default value is 1.

The MAC address used by this Bridge when it is referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this Bridge. However, it is only required to be unique. When concatenated with ieee8021SpanningTreePriority, a unique BridgeIdentifier is formed, which is used in the Spanning Tree Protocol. This object may not be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1). The value of this object MUST be retained across reinitializations of the management system.

The number of ports controlled by this bridging entity.

Indicates the component type(s) of this Bridge. The following component types are possible: iComponent(1) - An S-VLAN component of a Backbone Edge Bridge which performs encapsulation of customer frames. bComponent(2) - An S-VLAN component of a Backbone Edge Bridge which bundles backbone service instances into B-VLANs. cVlanComponent(3) - A C-VLAN component of an enterprise VLAN Bridge or of a Provider Bridge used to process C-tagged frames. sVlanComponent(4) - An S-VLAN component of a Provider Bridge. dBridgeComponent(5) - A VLAN unaware component of an IEEE 802.1Q Bridge. erComponent (6) - An Edge Relay component of an EVB Station. tComponent (7) - A TPMR component in a Backbone Edge Bridge. This object may not be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1). The value of this object MUST be retained across reinitializations of the management system. Enumeration: 'sVlanComponent': 4, 'iComponent': 1, 'bComponent': 2, 'tComponent': 7, 'cVlanComponent': 3, 'dBridgeComponent': 5, 'erComponent': 6.

Indicates the optional parts of 802.1Q that are implemented by this device and are manageable through this MIB. Capabilities that are allowed on a per-port basis are indicated in ieee8021BridgeBasePortCapabilities. dot1dExtendedFilteringServices(0), -- can perform filtering of -- individual multicast addresses -- controlled by MMRP. dot1dTrafficClasses(1), -- can map priority to -- multiple traffic classes. dot1qStaticEntryIndividualPort(2), -- dot1qStaticUnicastReceivePort & -- dot1qStaticMulticastReceivePort -- can represent non-zero entries. dot1qIVLCapable(3), -- Independent VLAN Learning (IVL). dot1qSVLCapable(4), -- Shared VLAN Learning (SVL). dot1qHybridCapable(5), -- both IVL & SVL simultaneously. dot1qConfigurablePvidTagging(6), -- whether the implementation -- supports the ability to -- override the default PVID -- setting and its egress status -- (VLAN-Tagged or Untagged) on -- each port. dot1dLocalVlanCapable(7) -- can support multiple local -- Bridges, outside of the scope -- of 802.1Q defined VLANs. This object may not be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1). The value of this object MUST be retained across reinitializations of the management system. Bits: 'dot1dExtendedFilteringServices': 0, 'dot1dLocalVlanCapable': 7, 'dot1qConfigurablePvidTagging': 6, 'dot1qSVLCapable': 4, 'dot1qIVLCapable': 3, 'dot1qStaticEntryIndividualPort': 2, 'dot1dTrafficClasses': 1, 'dot1qHybridCapable': 5.

The value true(1) indicates that Traffic Classes are enabled on this Bridge. When false(2), the Bridge operates with a single priority level for all traffic. This object may be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1). The value of this object MUST be retained across reinitializations of the management system.

The administrative status requested by management for MMRP. The value true(1) indicates that MMRP should be enabled on this device, in all VLANs, on all ports for which it has not been specifically disabled. When false(2), MMRP is disabled, in all VLANs and on all ports, and all MMRP packets will be forwarded transparently. This object affects both Applicant and Registrar state machines. A transition from false(2) to true(1) will cause a reset of all MMRP state machines on all ports. This object may be modified while the corresponding instance of ieee8021BridgeBaseRowStatus is active(1). The value of this object MUST be retained across reinitializations of the management system.

The object indicates the status of an entry, and is used to create/delete entries. The following objects MUST be set prior to making a new entry active: ieee8021BridgeBaseBridgeAddress ieee8021BridgeBaseComponentType ieee8021BridgeBaseDeviceCapabilities It is recommended that these three objects not be allowed to be modified while the corresponding instance of ieee8021BridgeBaseRowStatus object is active(1). The following objects are not required to be set before making a new entry active (they will take their defaults), and they also may be modified while the corresponding instance of this object is active(1): ieee8021BridgeBaseTrafficClassesEnabled ieee8021BridgeBaseMmrpEnabledStatus The value of this object and all corresponding instances of other objects in this table MUST be retained across reinitializations of the management system.

The underlying IfEntry indexed by this column MUST be persistent across reinitializations of the management system.

The number of frames discarded by this port due to excessive transit delay through the Bridge. It is incremented by both transparent and source route Bridges. Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).

The number of frames discarded by this port due to an excessive size. It is incremented by both transparent and source route Bridges. Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).

Indicates the parts of IEEE 802.1Q that are optional on a per-port basis, that are implemented by this device, and that are manageable through this MIB. dot1qDot1qTagging(0), -- supports 802.1Q VLAN tagging of -- frames and MVRP. dot1qConfigurableAcceptableFrameTypes(1), -- allows modified values of -- dot1qPortAcceptableFrameTypes. dot1qIngressFiltering(2) -- supports the discarding of any -- frame received on a Port whose -- VLAN classification does not -- include that Port in its Member -- set. Bits: 'dot1qIngressFiltering': 2, 'dot1qDot1qTagging': 0, 'dot1qConfigurableAcceptableFrameTypes': 1.

Indicates the capabilities of this port. The corresponding instance of ieee8021BridgeBasePortType can potentially take any of the values for which the corresponding bit in this object is 1. The possible port types are as follows: customerVlanPort(0) - Indicates the port can be a C-TAG aware port of an enterprise VLAN aware Bridge. providerNetworkPort(1) - Indicates the port can be an S-TAG aware port of a Provider Bridge or Backbone Edge Bridge used for connections within a PBN or PBBN. customerNetworkPort(2) - Indicates the port can be an S-TAG aware port of a Provider Bridge or Backbone Edge Bridge used for connections to the exterior of a PBN or PBBN. customerEdgePort(3) - Indicates the port can be a C-TAG aware port of a Provider Bridge used for connections to the exterior of a PBN or PBBN. customerBackbonePort(4) - Indicates the port can be a I-TAG aware port of a Backbone Edge Bridge's B-component. virtualInstancePort(5) - Indicates the port can be a virtual S-TAG aware port within a Backbone Edge Bridge's I-component which is responsible for handling S-tagged traffic for a specific backbone service instance. dBridgePort(6) - Indicates the port can be a VLAN-unaware member of an 802.1Q Bridge. remoteCustomerAccessPort(7) - Indicates the port can be an S-TAG aware port of a Provider Bridge capable of providing Remote Customer Service Interfaces. stationFacingBridgePort(8) - Indicates the station-facing Bridge Port in a EVB Bridge. uplinkAccessPort(9) - Indicates the uplink access port in an EVB Bridge or EVB station. uplinkRelayPort (10) - Indicates the uplink relay port in an EVB station.

The port type. This value MUST be persistent over power up restart/reboot.

A boolean indicating whether the port is external. A value of true(1) means the port is external. A value of false(2) means the port is internal.

For a port running spanning tree, this object represents the administrative point-to-point status of the LAN segment attached to this port, using the enumeration values of IEEE Std 802.1AC. A value of forceTrue(1) indicates that this port should always be treated as if it is connected to a point-to-point link. A value of forceFalse(2) indicates that this port should be treated as having a shared media connection. A value of auto(3) 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. Manipulating this object changes the underlying adminPointToPointMAC. For a VIP, the adminPointToPointMAC parameter controls the mechanism by which the Default Backbone Destination parameter for the VIP is determined. For a backbone service instance that includes only 2 VIPs, the value may be set to forceTrue(1) which permits dynamic learning of the Default Backbone Destination parameter. For a backbone service instance that includes more than 2 VIPs, the value MUST be set to ForceFalse(2) or auto(3). When this object is set to forceTrue(1) for a VIP, the Default Backbone Destination parameter is modified by the subsequent M_UNITDATA.indications as specified in 6.10.1 (and described in 26.4.1). Whenever the parameter is set to forceFalse(2) or auto(3), the value for the Default Backbone Destination parameter is set to the Backbone Service Instance Group Address for the VIP-ISID. The value of this object MUST be retained across reinitializations of the management system. Enumeration: 'forceFalse': 2, 'forceTrue': 1, 'auto': 3.

For a port running spanning tree, this object represents 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. If adminPointToPointMAC is set to auto(2), then the value of operPointToPointMAC is determined in accordance with the specific procedures defined for the MAC entity concerned, as defined in IEEE Std 802.1AC. The value is determined dynamically; that is, it is re-evaluated whenever the value of adminPointToPointMAC changes, and whenever the specific procedures defined for the MAC entity evaluate a change in its point-to-point status. For a VIP, this object simply reflects the value of the corresponding instance of ieee8021BridgeBasePortAdminPointToPoint. The value will be true(1) if that object is forceTrue(1), and the value will be false(2) if the value of that object is either forceFalse(2) or auto(3).

Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).

The number of frames that have been transmitted by this port to its segment. Note that a frame transmitted on the interface corresponding to this port is only counted by this object if and only if it is for a protocol being processed by the local bridging function, including Bridge management frames. Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).

Count of received valid frames that were discarded (i.e., filtered) by the Forwarding Process.

A list of Default User Priorities for each port of a transparent Bridge. This is indexed by ieee8021BridgeBasePortComponentId and ieee8021BridgeBasePort.

The default ingress priority for this port. This only has effect on media, such as Ethernet, that do not support native priority. The value of this object MUST be retained across reinitializations of the management system.

The number of egress traffic classes supported on this port. This object may optionally be read-only. The value of this object MUST be retained across reinitializations of the management system.

This object identifies the rows in the PCP encoding and decoding tables that are used to remark frames on this port if this remarking is enabled.

If the Use_DEI is set to true(1) for the Port then the drop_eligible parameter is encoded in the DEI of transmitted frames, and the drop_eligible parameter shall be true(1) for a received frame if the DEI is set in the VLAN tag or the Priority Code Point Decoding Table indicates drop_eligible True for the received PCP value. If the Use_DEI parameter is false(2), the DEI shall be transmitted as zero and ignored on receipt. The default value of the Use_DEI parameter is false(2).

If a Bridge supports encoding or decoding of drop_eligible from the PCP field of a VLAN tag (6.7.3) on any of its Ports, then it shall implement a Boolean parameter Require Drop Encoding on each of its Ports with default value false(2). If Require Drop Encoding is True and the Bridge Port cannot encode particular priorities with drop_eligible, then frames queued with those priorities and drop_eligible true(1) shall be discarded and not transmitted.

Indication of whether the Service Access Priority Selection function is supported on the Customer Bridge Port to request priority handling of the frame from a Port-based service interface.

A list of Regenerated User Priorities for each received priority on each port of a Bridge. The regenerated priority value may be used to index the Traffic Class Table for each input port.

For untagged frames received from Ethernet media, this value is equal to the ieee8021BridgePortDefaultUserPriority value for the ingress port. For untagged frames received from non-Ethernet media, this value is equal to the ieee8021BridgeRegenUserPriority value for the ingress port and media-specific priority.

The Traffic Class the received frame is mapped to. The value of this object MUST be retained across reinitializations of the management system.

A table of MMRP control and status information about every Bridge Port. Augments the ieee8021BridgeBasePortTable.

MMRP control and status information for a Bridge Port.

The administrative state of MMRP operation on this port. The value true(1) indicates that MMRP is enabled on this port in all VLANs as long as ieee8021BridgeMmrpEnabledStatus is also true(1). A value of false(2) indicates that MMRP is disabled on this port in all VLANs: any MMRP packets received will be silently discarded, and no MMRP registrations will be propagated from other ports. Setting this to a value of true(1) will be stored by the agent but will only take effect on the MMRP protocol operation if ieee8021BridgeMmrpEnabledStatus also indicates the value true(1). This object affects all MMRP Applicant and Registrar state machines on this port. A transition from false(2) to true(1) will cause a reset of all MMRP state machines on this port.

The value of this object MUST be retained across reinitializations of the management system.

This table is a sparse augmentation of ifTable and controls the creation of the I-LAN Interface. An I-LAN Interface is used to create internal connections between Bridge Ports in a 802.1 device. An I-LAN Interfaces can be directly associated with a set of Bridge Ports. An I-LAN Interfaces can also be used as a stacking interface to relate other interfaces before association to Bridge Ports. For example, an I-LAN interface can be created to link traffic between a PIP and a CBP. In this case a CBP is created on the B-Component and the CBP's related IfEntry is stacked upon the IfEntry of the I-LAN. The PIP is stacked upon the I-LAN using the IfStackTable. Finally, a VIP is created on the I-Component and is associated with the PIP, thus completing the path from the I-Component's MAC relay to the CBP on the B-Component. Entries in this table MUST be persistent over power up restart/reboot.

Each entry consists of a Row Status to control creation.

This object is used to create and delete entries in this table and the Interface table.
