The Bridge MIB Extension module for managing Priority and Multicast Filtering, defined by IEEE 802.1D-1998, including Restricted Group Registration defined by IEEE 802.1t-2001.
Copyright (C) The Internet Society (2006). This version of this MIB module is part of RFC 4363; See the RFC itself for full legal notices.
Indicates the optional parts of IEEE 802.1D and 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 dot1dPortCapabilities.
dot1dExtendedFilteringServices(0), -- can perform filtering of -- individual multicast addresses -- controlled by GMRP. dot1dTrafficClasses(1), -- can map user 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.
dot1dTrafficClassesEnabled
1.3.6.1.2.1.17.6.1.1.2
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
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.
The value of this object MUST be retained across reinitializations of the management system.
dot1dGmrpStatus
1.3.6.1.2.1.17.6.1.1.3
EnabledStatus1 = enabled2 = disabledA simple status value for the object. · Integer32
The administrative status requested by management for GMRP. The value enabled(1) indicates that GMRP should be enabled on this device, in all VLANs, on all ports for which it has not been specifically disabled. When disabled(2), GMRP is disabled, in all VLANs and on all ports, and all GMRP packets will be forwarded transparently. This object affects both Applicant and Registrar state machines. A transition from disabled(2) to enabled(1) will cause a reset of all GMRP state machines on all ports.
The value of this object MUST be retained across reinitializations of the management system.
Table details
dot1dTpHCPortTable
1.3.6.1.2.1.17.4.5
Index: dot1dTpPort
A table that contains information about every high- capacity port that is associated with this transparent bridge.
The port number of the port for which this entry contains Transparent bridging management information.
dot1dTpHCPortInFrames
1.3.6.1.2.1.17.4.5.1.1
Counter64 (0..18446744073709551615)
Reference: ISO/IEC 15802-3 Section 14.6.1.1.3
The number of frames that have been received by this port from its segment. Note that a frame received 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.
dot1dTpHCPortOutFrames
1.3.6.1.2.1.17.4.5.1.2
Counter64 (0..18446744073709551615)
Reference: ISO/IEC 15802-3 Section 14.6.1.1.3
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.
dot1dTpHCPortInDiscards
1.3.6.1.2.1.17.4.5.1.3
Counter64 (0..18446744073709551615)
Reference: ISO/IEC 15802-3 Section 14.6.1.1.3
Count of valid frames that have been received by this port from its segment that were discarded (i.e., filtered) by the Forwarding Process.
dot1dTpPortOverflowTable
1.3.6.1.2.1.17.4.6
Index: dot1dTpPort
A table that contains the most-significant bits of statistics counters for ports that are associated with this transparent bridge that are on high-capacity interfaces, as defined in the conformance clauses for this table. This table is provided as a way to read 64-bit counters for agents that support only SNMPv1.
Note that the reporting of most-significant and least-significant counter bits separately runs the risk of missing an overflow of the lower bits in the interval between sampling. The manager must be aware of this possibility, even within the same varbindlist, when interpreting the results of a request or asynchronous notification.
Indicates the parts of IEEE 802.1D and 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 GVRP. 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.

Reference: ISO/IEC 15802-3 Section 6.4
A list of Regenerated User Priorities for each received User Priority on each port of a bridge. The Regenerated User Priority value may be used to index the Traffic Class Table for each input port. This only has effect on media that support native User Priority. The default values for Regenerated User Priorities are the same as the User Priorities.

dot1dTrafficClassPriority
1.3.6.1.2.1.17.6.1.2.3.1.1
Integer32 (0..7)
The Priority value determined for the received frame. This value is equivalent to the priority indicated in the tagged frame received, or one of the evaluated priorities, determined according to the media-type.

For untagged frames received from non-Ethernet media, this value is equal to the dot1dRegenUserPriority value for the ingress port and media-specific user priority.

dot1dPortGmrpStatus
1.3.6.1.2.1.17.6.1.4.1.1.1
EnabledStatus1 = enabled2 = disabledA simple status value for the object. · Integer32
The administrative state of GMRP operation on this port. The value enabled(1) indicates that GMRP is enabled on this port in all VLANs as long as dot1dGmrpStatus is also enabled(1). A value of disabled(2) indicates that GMRP is disabled on this port in all VLANs: any GMRP packets received will be silently discarded, and no GMRP registrations will be propagated from other ports. Setting this to a value of enabled(1) will be stored by the agent but will only take effect on the GMRP protocol operation if dot1dGmrpStatus also indicates the value enabled(1). This object affects all GMRP Applicant and Registrar state machines on this port. A transition from disabled(2) to enabled(1) will cause a reset of all GMRP state machines on this port.
The value of this object MUST be retained across reinitializations of the management system.
dot1dPortGmrpFailedRegistrations
1.3.6.1.2.1.17.6.1.4.1.1.2

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