| Ieee8021CnControlChoice TEXTUAL-CONVENTION This controls what other object selects the CND defense mode and the Congestion Notification Priority Value (CNPV) alternate priority for a CNPV in an end station or Bridge component, or for a CNPV on a particular Port in an end station or Bridge component. It can take the following values: cpcAdmin(1) The CND defense mode and alternate priority are controlled by the administrative variables in the same table entry as this object. cpcAuto(2) This Port or all Ports' CND defense modes are controlled automatically, as indicated by ieee8021CnPortPriAutoDefenseMode, and the alternate priority by ieee8021CnComPriAutoAltPri. cpcComp(3) This CND defense mode and alternate priority are both controlled by ieee8021CnPortPriTable. | current | |||
| Ieee8021CnDefenseMode TEXTUAL-CONVENTION For a given Congestion Notification Priority Value (CNPV), a port can operate in one of four CND defense modes. The CND defense mode determines whether congestion notification is enabled or not, and if enabled, whether the port translates the CNPV to a non-CNPV value on input, and whether the port removes CN-TAGs on output. cptDisabled(1) The congestion notification capability is administratively disabled for this priority value and port. This priority is not a CNPV. The priority regeneration table controls the remapping of input frames on this port for this priority. CN-TAGs are neither added by an end station nor stripped by a Bridge. cptInterior(2) On this port and for this CNPV, the priority parameters of input frames are not remapped, regardless of the priority regeneration table. CN-TAGs are not added by an end station, and are removed from frames before being output by a Bridge. cptInteriorReady(3) On this port and for this CNPV, the priority parameters of input frames are not remapped, regardless of the priority regeneration table. CN-TAGs can be added by an end station, and are not removed from frames by a Bridge. cptEdge(4) On this port and for this CNPV, the priority parameters of input frames are remapped to an alternate (non-CNPV) value, regardless of the priority regeneration table. CN-TAGs are not added by an end station, and are removed from frames before being output by a Bridge. This mode is optional for an end station. | current | |||
| Ieee8021CnLldpChoice TEXTUAL-CONVENTION Specifies how to determine what index value is to be used as the index to lldpDestAddressTable, the table of destination MAC addresses, for both the destination addresses on transmitted LLDPDUs and on received LLDPDUs, found in the LLDP-MIB, either: cnlNone(1) No LLDP Congestion Notification TLV is to carry Per-priority CNPV indicators or Per-priority Ready indicators on this Port for this priority (or all Ports and all priorities, as appropriate to the managed object). cnlAdmin(2) The administrative LLDP instance selector in the same table entry as this object governs which LLDP instance will carry the Per-priority CNPV indicators and Per-priority Ready indicators for this priority in its Congestion Notification TLV on this Port (or all Ports and all priorities, as appropriate to the managed object). cnlComponent(3) ieee8021CnComPriLldpInstanceSelector governs LLDP instance selection for this Port and priority. | current |

Upon a restart of the system, the system SHALL, if necessary, change the value of this variable so that it references the row in the ifXTable with the same value of ifAlias that it referenced before the system restart. If no such row exists, then the system SHALL delete this row in the ieee8021CnErroredPortTable. | 1.3.111.2.802.1.1.18.1.2.1.3 | InterfaceIndex | read-only | current |
| ieee8021CnCompntPriTable OBJECT-TYPE Each row in this table supplies default values for one Congestion Notification Priority Value for a whole Bridge component or end station. Creating a row in this table makes the priority value of ieee8021CnComPriPriority a Congestion Notification Priority Value. Deleting a row in this table makes the value in the deleted ieee8021CnComPriPriority no longer a Congestion Notification Priority Value. A system SHALL NOT allow eight rows in this table to be created with the same value of ieee8021CnComPriComponentId; see the description of ieee8021CnComPriRowStatus. The contents of this table SHALL be maintained across a restart of the system. | 1.3.111.2.802.1.1.18.1.3 | not-accessible | current | |
| ieee8021CnCompntPriEntry OBJECT-TYPE One entry per Congestion Notification Priority Value per Bridge component or end station. | 1.3.111.2.802.1.1.18.1.3.1 | not-accessible | current | |
| ieee8021CnComPriComponentId OBJECT-TYPE The Bridge component within the system to which the information in this ieee8021CnCompntPriEntry applies.

| ieee8021CnComPriPriority OBJECT-TYPE The Congestion Notification Priority Value for which this row supplies default values. | 1.3.111.2.802.1.1.18.1.3.1.2 | IEEE8021PriorityValue | not-accessible | current |
| ieee8021CnComPriDefModeChoice OBJECT-TYPE Specifies how the default CND defense mode and alternate priority for this Congestion Notification Priority Value on all ports on this Bridge component or end station are to be chosen, either: cpcAdmin(1) Default CND defense mode is chosen by ieee8021CnComPriAdminDefenseMode, and alternate priority by ieee8021CnComPriAlternatePriority. cpcAuto(2) Default CND defense mode is chosen by ieee8021CnPortPriAutoDefenseMode, and alternate priority by ieee8021CnComPriAutoAltPri. This variable can be overridden by ieee8021CnPortPriDefModeChoice. | 1.3.111.2.802.1.1.18.1.3.1.3 | Ieee8021CnControlChoice {cpcAdmin(1), cpcAuto(2)} | read-create | current |
| ieee8021CnComPriAlternatePriority OBJECT-TYPE The Congestion Notification Priority Value to which an incoming frame is to be mapped, in spite of what the Priority Regeneration Table says, if 1) Congestion Notification is enabled and 2) the CND defense mode of the port is cptEdge. Deleting a row in this table does not alter the value of any other row's ieee8021CnComPriAlternatePriority. | 1.3.111.2.802.1.1.18.1.3.1.4 | IEEE8021PriorityValue | read-create | current |
| ieee8021CnComPriAutoAltPri OBJECT-TYPE The Congestion Notification Priority Value to which an incoming frame can be mapped, in spite of what the Priority Regeneration Table says, if 1) Congestion Notification is enabled, 2) the CND defense mode of the port is cptEdge, and 3) ieee8021CnComPriDefModeChoice contains the value cpcAuto(2). The value of this object is the next lower priority value than this row's ieee8021CnComPriPriority that is not a CNPV, or the next higher non-CNPV, if all lower values are CNPVs. The value of this object, and any consequent priority regeneration, is automatically updated by the managed system whenever a row in the ieee8021CnCompntPriTable is created or deleted. The value of this object is not dependent upon whether congestion notification is enabled or disabled for any priority or for the whole Bridge component or end station; it depends only upon whether the ieee8021CnCompntPriTable row exists. | 1.3.111.2.802.1.1.18.1.3.1.5 | IEEE8021PriorityValue | read-only | current |
| ieee8021CnComPriAdminDefenseMode OBJECT-TYPE The default CND defense mode for this Congestion Notification Priority Value on all ports on this Bridge component or end station.

This object can be overridden by ieee8021CnPortPriLldpInstanceChoice. | 1.3.111.2.802.1.1.18.1.3.1.8 | Ieee8021CnLldpChoice {cnlNone(1), cnlAdmin(2)} | read-create | current |
| ieee8021CnComPriLldpInstanceSelector OBJECT-TYPE Specifies a default value for which LLDP instance is to be used to provide the information for automatic configuration of ports' CND defense modes (ieee8021CnPortPriAutoDefenseMode). This object is ignored by the managed system if ieee8021CnComPriLldpInstanceChoice contains the value cnlNone (1). This object can be overridden by ieee8021CnPortPriLldpInstanceChoice and ieee8021CnPortPriLldpInstanceChoice. | 1.3.111.2.802.1.1.18.1.3.1.9 | LldpV2DestAddressTableIndex | read-create | current |
| ieee8021CnComPriRowStatus OBJECT-TYPE This object indicates the status of an entry, and is used to create/delete entries. A system SHALL NOT permit eight ieee8021CnComPriRowStatus objects, all with the same value of ieee8021CnComPriComponentId, to have the value active(1). An attempt to create or activate a row when there are already seven active rows SHALL result in that eighth row's ieee8021CnComPriRowStatus having the value notReady(3), and the return of an inconsistentValue error. | 1.3.111.2.802.1.1.18.1.3.1.10 | RowStatus | read-create | current |
| ieee8021CnPortPriTable OBJECT-TYPE Each row in this table supplies values for one port's Congestion Notification Priority Value (CNPV). Creating an entry in ieee8021CnCompntPriTable creates this entry, with the default values, on all ports in the Bridge component or end station. Deleting an entry in ieee8021CnCompntPriTable deletes this ieee8021CnCompntPriEntry on all ports in the Bridge component or end station. The contents of this table SHALL be maintained across a restart of the system, except as noted in the description of ieee8021CnPortPriIfIndex. | 1.3.111.2.802.1.1.18.1.4 | not-accessible | current | |

Upon a restart of the system, the system SHALL, if necessary, change the value of this object, and rearrange the order of the ieee8021CnPortPriTable, so that the value in ieee8021CnPortPriIfIndex references the row in the ifXTable with the same value for ifAlias that it referenced before the system restart. If no such entry exists in the ifXTable, then the system SHALL delete the row in the ieee8021CnPortPriTable. | 1.3.111.2.802.1.1.18.1.4.1.3 | InterfaceIndex | not-accessible | current |
| ieee8021CnPortPriDefModeChoice OBJECT-TYPE This object determines how the CND defense mode and alternate priority value of this port for this CNPV is to be selected, either: cpcAdmin(1) CND defense mode is controlled by ieee8021CnPortPriAdminDefenseMode, and alternate priority by ieee8021CnPortPriAlternatePriority. cpcAuto(2) CND defense mode is controlled by ieee8021CnPortPriAutoDefenseMode and alternate priority by ieee8021CnComPriAlternatePriority. cpcComp(3) CND defense mode and alternate priority are controlled by ieee8021CnComPriDefModeChoice. This variable can override ieee8021CnComPriDefModeChoice. | 1.3.111.2.802.1.1.18.1.4.1.4 | Ieee8021CnControlChoice | read-write | current |
| ieee8021CnPortPriAdminDefenseMode OBJECT-TYPE This object indicates the operator's choice for the CND defense mode in which this port is to operate for this CNPV whenever ieee8021CnPortPriDefModeChoice has the value cpcAdmin(1). This variable can override ieee8021CnComPriDefModeChoice. | 1.3.111.2.802.1.1.18.1.4.1.5 | Ieee8021CnDefenseMode | read-write | current |
| ieee8021CnPortPriAutoDefenseMode OBJECT-TYPE This object indicates in which the CND defense mode this port would operate for this CNPV as determined by the LLDP Congestion Notification TLV. | 1.3.111.2.802.1.1.18.1.4.1.6 | Ieee8021CnDefenseMode {cptInterior(2), cptInteriorReady(3), cptEdge(4)} | read-only | current |
| ieee8021CnPortPriLldpInstanceChoice OBJECT-TYPE Specifies how to determine the LLDP instance to be used for the Congestion Notification TLV, either: cnlNone(1) No LLDP Congestion Notification TLV is to carry Per-priority CNPV indicators or Per-priority Ready indicators on this Port for this priority. cnlAdmin(2) ieee8021CnPortPriLldpInstanceSelector governs which LLDP instance is to carry Per-priority CNPV indicators and Per-priority Ready indicators for this priority in its Congestion Notification TLV on this Port cnlComponent(3) ieee8021CnComPriLldpInstanceChoice governs LLDP instance selection for this Port and priority. This object can override ieee8021CnComPriLldpInstanceChoice. | 1.3.111.2.802.1.1.18.1.4.1.7 | Ieee8021CnLldpChoice | read-write | current |
| ieee8021CnPortPriLldpInstanceSelector OBJECT-TYPE This object determines which LLDP instance selector, if any, is used for automatic determination of the CND defense mode for this port and CNPV. This object can override ieee8021CnComPriLldpInstanceSelector. | 1.3.111.2.802.1.1.18.1.4.1.8 | LldpV2DestAddressTableIndex | read-write | current |
| ieee8021CnPortPriAlternatePriority OBJECT-TYPE The Congestion Notification Priority Value to which an incoming frame is to be mapped, in spite of what the Priority Regeneration Table says, if 1) Congestion Notification is enabled and 2) the port is acting in the cptEdge (4) CND defense mode. This object is ignored unless ieee8021CnPortPriDefModeChoice contains the value cpcAdmin (1). | 1.3.111.2.802.1.1.18.1.4.1.9 | IEEE8021PriorityValue | read-write | current |
| ieee8021CnCpTable OBJECT-TYPE Each row in this table supplies values for one Congestion Point (CP). This table is indexed by component, port (interface), and an arbitrary CP index. This arbitrary CP index is not necessarily the Congestion Point Identifier (CPID) carried in Congestion Notification Messages (CNMs). Creating an entry in ieee8021CnCompntPriTable can create an entry in this table, with the default values, on all ports in the Bridge component or end station. Because more than one Congestion Notification Priority Value (CNPV) can flow through a single CP, the creation of an entry in ieee8021CnCompntPriTable does not necessarily create a new entry in this table. An end station can have more than one CP for the same CNPV, so creating an entry in ieee8021CnCompntPriTable can create multiple entries in this table. Because each port in a Bridge component or end station can have a different relationship between CNPVs and CPs, the entries created or deleted on each port can be different. Deleting the last entry in ieee8021CnCompntPriTable for a CNPV passing through the CP controlled by this entry deletes the entry on some or all of the ports in the Bridge component or end station. Because each port in a Bridge component or end station can have a different relationship between CNPVs and CPs, the entries created or deleted on each port can be different. The relationship between ieee8021CnCpIndex values and CPs is an implementation dependent matter. The contents of this table SHALL be maintained across a restart of the system, except as noted in the description of ieee8021CnCpIfIndex. | 1.3.111.2.802.1.1.18.1.5 | not-accessible | current | |

| ieee8021CnCpComponentId OBJECT-TYPE The Bridge component within the system to which the information in this ieee8021CnCpEntry applies. If the system is not a Bridge, or if only one component is present in the Bridge, then this variable (index) MUST be equal to 1. | 1.3.111.2.802.1.1.18.1.5.1.1 | IEEE8021PbbComponentIdentifier | not-accessible | current |
| ieee8021CnCpIfIndex OBJECT-TYPE This object represents the port or aggregated port to which the entry applies. Upon a restart of the system, the system SHALL, if necessary, change the value of this object, and rearrange the order of the ieee8021CnCpTable, so that the value in ieee8021CnCpIfIndex references the row in the ifXTable with the same value for ifAlias that it referenced before the system restart. If no such entry exists in the ifXTable, then the system SHALL delete the row in the ieee8021CnCpTable. | 1.3.111.2.802.1.1.18.1.5.1.2 | InterfaceIndex | not-accessible | current |
| ieee8021CnCpIndex OBJECT-TYPE This object is an arbitrary integer indexing the entries in this table among the entries for the same component and interface.

Otherwise, it SHOULD be a small integer value. | 1.3.111.2.802.1.1.18.1.5.1.3 | Unsigned32 (1..4096) | not-accessible | current |
| ieee8021CnCpPriority OBJECT-TYPE This object indicates the lowest numerical Congestion Notification Priority Value that this entry's Congestion Point serves. | 1.3.111.2.802.1.1.18.1.5.1.4 | IEEE8021PriorityValue | read-only | current |
| ieee8021CnCpMacAddress OBJECT-TYPE This object indicates the MAC address used as the source address in Congestion Notification Message transmitted by this Congestion Point. | 1.3.111.2.802.1.1.18.1.5.1.5 | MacAddress | read-only | current |
| ieee8021CnCpIdentifier OBJECT-TYPE This object indicates the Congestion Point Identifier (CPID) transmitted in Congestion Notification Message by this Congestion Point. It is not specified whether the CPID reported in a CNM by a CP that serves multiple CNPVs does or does not have the same value for its different CNPVs. | 1.3.111.2.802.1.1.18.1.5.1.6 | OCTET STRING (SIZE(8)) | read-only | current |
| ieee8021CnCpQueueSizeSetPoint OBJECT-TYPE This object is the set point for the queue managed by this Congestion Point (CP). Congestion Notification Messages are transmitted to the sources of frames queued in this CP's queue in order to keep the total number of octets stored in the queue at this set point. | 1.3.111.2.802.1.1.18.1.5.1.7 | Unsigned32 (100..4294967295) | read-write | current |

| ieee8021CnCpDiscardedFrames OBJECT-TYPE The number of data frames discarded by the queue controlled by this Congestion Point due to queue congestion. Discontinuities in the value of this 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). | 1.3.111.2.802.1.1.18.1.5.1.10 | Counter64 | read-only | current |
| ieee8021CnCpTransmittedFrames OBJECT-TYPE The number of data frames passed on to the queue controlled by this Congestion Point that were not discarded due to queue congestion.

| ieee8021CnRpGroupTable OBJECT-TYPE Each row in this table supplies values for one or more Reaction Points (RPs). This table is indexed by component, port (interface), and an arbitrary RP index. Creating an entry in ieee8021CnCompntPriTable can create an entry in this table, with the default values, on all ports in the end station. An end station can have more than one RP for the same Congestion Notification Priority Value (CNPV), so creating an entry in ieee8021CnCompntPriTable can create multiple entries in this table. Because each port in a Bridge component or end station can have a different relationship between CNPVs and RPs, the entries created or deleted on each port can be different. Deleting the an entry in ieee8021CnCompntPriTable for a CNPV passing through the RP controlled by this entry deletes entries on some or all of the ports in the end station. Because each port in an end station can have a different relationship between CNPVs and RPs, the entries created or deleted on each port can be different. The relationship between ieee8021CnRpgIdentifier values and RPs is an implementation dependent matter.
