SHE-GBOND-MIB: View SNMP OID List / Download MIB

The objects in this MIB module are used to manage the multi-pair bonded xDSL Interfaces, defined in ITU-T recommendations G.998.1, G.998.2. This MIB module contain information for a used bonding scheme specific as GBOND-ATM or GBOND-ETH. The following references are used throughout this MIB module: [G.998.1] refers to: ITU-T Recommendation G.998.1: 'ATM-based multi-pair bonding', January 2005. [G.998.2] refers to: ITU-T Recommendation G.998.1: 'Ethernet-based multi-pair bonding', January 2005. [WT-157] refers to: DSL Forum Technical Report: 'Management Framework for xDSL Bonding', January 2007. Naming Conventions: BCE - Bonding Channel Entity CO - Central Office CPE - Customer Premises Equipment GBS - Generic Bonding Sublayer SNR - Signal to Noise Ratio

This table should be used to build a bonding group.

A ifIndex with ifType atmbond(234) will represent a GBondPort of bondingtype atm. A ifIndex with ifType ethbond(500) will represent a GBondPort of bondingtype eth. Note: The ifType ethbond is currently not defined by IANA and this value is a proprietary define!

The list of bonded interfaces. Each entry consist of three octets which consist of two octets for ifIndex and one octet for channelnumber like [16-bit ifIndex, 8-bit channelnumber]. The first two octets representing the ifIndex of the bonded interface. A single interface could only be one time member of this list. The third octet, represents a valid channelnumber because the maximum number of channels per interface is 2. Bonding of multiple channels from the same physical interface in one group is not allowed. A ifIndex-channelnumber couple could be always member of only one bond in the NE. Important Note: Only existing ifIndex-channelnumber combinations could be configured. The VCI setting of VccTp connections which are transported via the selected channels should have a restricted value range (32..255) to support needed SID numbering for atm bonding. The current available chipset HW and chipset firmware has additional restrictions for the amount of ifIndex numbers, which could be bonded in one group. These are: 1. All ifIndeces has to be placed on the same IU board. 2. A maximum number of 4 interfaces/channels could be bonded in one group. 3. On one IU board only Indeces which are members of the same group could be bonded. 4. Additional restriction for board IU_SHDSL48:IFX (only ethbond possible). On this IU board only Indeces which are members of the same group of always 4 consecutive ports could be bonded. Out of these groups the following bonds are possible: 1-2 and 3-4, 1-2-3 or 1-2-3-4 5. Additional restriction for board IU_VDSL48:IFX (only ethbond possible). Only ports which are members of the same group out of 8 consecutive ports could be bonded. These groups are: Group1(1,2,5,6) and Group2(3,4,7,8). Out of these groups the following bonds are possible: 1-2,5-6,3-4,7-8,1-2-5,3-4-7,1-2-5-6,1-4-7-8 6. Additional restriction for board IU_ADSL72:CGH (only atmbond possible). Only ports out of 8 consecutive ports could be bonded. Out of these groups the following bonds are possible: 1-2,3-4,5-6,7-8,1-2-3,5-6-7,1-2-3-4,5-6-7-8 R2.8 will only support ethbond for IU_SHDSL48:IFX!!

Describes if it is an ATM or Ethernet bond. Depending on this parameter, only interfaces which support the requested bonding type could be added to the sheGBondPortStackAssignedIfList for this bondingport. Note: The used ifTypes for new created Gbond-port in the ifTable are atmbond(234) and ethbond(500). The value ethbond(500) is a proprietary defined value, because there is no official definition from IANA available up to now!

Table for Configuration of G.Bond GBS ports. Entries in this table MUST be maintained in a persistent manner

An entry in the G.Bond Port Configuration table. Each entry represents an G.Bond port indexed by the ifIndex. Note that an G.Bond GBS port runs on top of a single or multiple BCE port(s), which are also indexed by ifIndex and channelnumber.

A Discovery Code of the G.Bond port (GBS). A unique 6 octet long code used by the Discovery function. This object MUST be instantiated for the -O subtype GBS before writing operations on the sheGBondRemoteDiscoveryCode (Set_if_Clear and Clear_if_Same) are performed by BCEs associated with the GBS. The initial value of this object for -R subtype ports after reset is all zeroes. For -R subtype ports, the value of this object cannot be changed directly. This value may be changed as a result of writing operation on the sheGBondRemoteDiscoveryCode object of remote BCE of -O subtype, connected to one of the local BCEs associated with the GBS. Discovery MUST be performed when the link is Down. Attempts to change this object MUST be rejected (in case of SNMP with the error inconsistentValue), if the link is Up or Initializing. NOTE: NE will always ignore any setting for this parameter and IU select a valid code during handshake phase.

A desired G.Bond port Data Rate in the upstream direction, in Kbps, to be achieved during initialization, under restrictions placed upon the member BCEs by their respective configuration settings. This object represents a sum of individual BCE upstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g. for an Ethernet service, the target data rate of 10Mbps SHALL allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). Note that the target upstream data rate may not be achieved during initialization (e.g. due to unavailability of required BCEs) or the initial bandwidth could deteriorate, so that the actual upstream data rate (sheGBondUpDataRate) could be less than sheGBondTargetUpDataRate. The value between 1 and 1000000 indicates that the total upstream data rate of the G.Bond port after initialization SHALL be equal to the target data rate or less, if the target upstream data rate cannot be achieved under the restrictions configured for BCEs. In case the copper environment allows to achieve higher upstream data rate than that specified by this object, the excess capability SHALL be either converted to additional SNR margin or reclaimed by minimizing transmit power. The value of 9999999 means that the target data rate is not fixed and SHALL be set to the maximum attainable rate during initialization (Best Effort), under specified spectral restrictions and with desired SNR Margin per BCE. This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes. Changing of the Target Upstream Data Rate MUST be performed when the link is Down. Attempts to change this object MUST be rejected (In case of SNMP with the error inconsistentValue), if the link is Up or Initializing. This object MUST be maintained in a persistent manner. NOTE: Not configurable for VDSL2 based GBOND interfaces.

A desired G.Bond port Data Rate in the downstream direction, in Kbps, to be achieved during initialization, under restrictions placed upon the member BCEs by their respective configuration settings. This object represents a sum of individual BCE downstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g. for an Ethernet service, the target data rate of 10Mbps SHALL allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). Note that the target downstream data rate may not be achieved during initialization (e.g. due to unavailability of required BCEs) or the initial bandwidth could deteriorate, so that the actual downstream data rate (sheGBondDownDataRate) could be less than sheGBondTargetDownDataRate. The value between 1 and 1000000 indicates that the total downstream data rate of the G.Bond port after initialization SHALL be equal to the target data rate or less, if the target downstream data rate cannot be achieved under the restrictions configured for BCEs. In case the copper environment allows to achieve higher downstream data rate than that specified by this object, the excess capability SHALL be either converted to additional SNR margin or reclaimed by minimizing transmit power. The value of 9999999 means that the target data rate is not fixed and SHALL be set to the maximum attainable rate during initialization (Best Effort), under specified spectral restrictions and with desired SNR Margin per BCE. This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes. Changing of the Target Downstream Data Rate MUST be performed when the link is Down. Attempts to change this object MUST be rejected (In case of SNMP with the error inconsistentValue), if the link is Up or Initializing. This object MUST be maintained in a persistent manner. NOTE: Not configurable for VDSL2 based GBOND interfaces.

This object configures the G.Bond port low upstream rate crossing alarm threshold. When the current value of sheGBondUpDataRate for this port reaches/drops below or exceeds this threshold, a sheGBondLowUpRateCrossing notification MAY be generated if enabled by sheGBondLowRateCrossingEnable. This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes. This object MUST be maintained in a persistent manner. NOTE: Not configurable for VDSL2 based GBOND interfaces.

This object configures the G.Bond port low downstream rate crossing alarm threshold. When the current value of sheGBondDownDataRate for this port reaches/drops below or exceeds this threshold, a sheGBondLowDownRateCrossing notification MAY be generated if enabled by sheGBondLowRateCrossingEnable. This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes. This object MUST be maintained in a persistent manner. NOTE: Not configurable for VDSL2 based GBOND interfaces.

Indicates whether sheGBondLowUpRateCrossing and sheGBondLowDownRateCrossing notifications should be generated for this interface. Value of true(1) indicates that the notifications are enabled. Value of false(2) indicates that the notifications are disabled. This object is valid for the -O subtype G.Bond ports and irrelevant for the -R subtypes. This object MUST be maintained in a persistent manner. NOTE: Not configurable for VDSL2 based GBOND interfaces.

An entry in the G.Bond Port Capability table. Each entry represents an G.Bond port indexed by the ifIndex. Note that a G.Bond GBS port runs on top of a single or multiple BCE port(s), which are also indexed by ifIndex and channelnumber.

Bonding Capability of the G.Bond port (GBS) link partner. This object has a value of true(1) when the remote GBS supports the same bonding scheme as the local port. A value of false(2) is returned when the remote GBS does not support the same bonding scheme. Ports whose peers cannot be reached because of the link state, SHALL return a value if unknown(0). This object maps to the WT-157 attribute aGroupPeerBndScheme.

Number of BCEs that can be aggregated by the local GBS. The number of BCEs currently assigned to a particular G.Bond port (sheGBondNumBCEs) is never greater than sheGBondCapacity. This object maps to the WT-157 attribute aGroupCapacity.

Number of BCEs that can be aggregated by the peer GBS port. Value of 0 is returned when peer Bonding Capacity is unknown (peer cannot be reached). This object maps to the WT-157 attribute aGroupRemoteCapacity.

This table provides overall status information of G.Bond ports, complementing the generic status information from the ifTable of IF-MIB. Additional status information about connected BCEs is available from the relevant line MIBs This table contains live data from the equibcent. As such, it is NOT persistent.

An entry in the G.Bond Port Status table. Each entry represents an G.Bond port indexed by the ifIndex. Note that an G.Bond GBS port runs on top of a single or multiple BCE port(s), which are also indexed by ifIndex and channelnumber.

A current G.Bond port operational Data Rate in the upstream direction, in bps. This object represents an estimation of the sum of individual BCE upstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g. for an Ethernet service, the target data rate of 10Mbps SHALL allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). Note that for symmetrical interfaces sheGBondUpDataRate == sheGBondDownDataRate == ifSpeed.

A current G.Bond port operational Data Rate in the downstream direction, in bps. This object represents an estimation of the sum of individual BCE downstream data rates, modified to compensate for fragmentation and encapsulation overhead (e.g. for an Ethernet service, the target data rate of 10Mbps SHALL allow lossless transmission of full-duplex 10Mbps Ethernet frame stream with minimal inter-frame gap). Note that for symmetrical interfaces sheGBondUpDataRate == sheGBondDownDataRate == ifSpeed.

G.Bond (GBS) port Fault Status. This is a bitmap of possible conditions. The various bit positions are: noPeer - peer PHY cannot be reached (e.g. no BCEs attached, all BCEs are Down etc.). peerPowerLoss - peer PHY has indicated impending unit failure due to loss of local power ('Dying Gasp'). bceSubTypeMismatch - local BCEs in the aggregation group are not of the same sub-type, e.g. some BCEs in the local device are -O while others are -R subtype. lowRate - sheGBondUpRate/sheGBondDownRate of the port has reached or dropped below sheGBondThreshLowUpRate/ sheGBondThreshLowUpRate. This object is intended to supplement ifOperStatus object in IF-MIB.

G.Bond port mode of operation (subtype). The value of 'subscriber' indicates the port is designated as '-R' subtype (all BCEs assigned to this port are of subtype '-R'). The value of the 'office' indicates that the port is designated as '-O' subtype (all BCEs assigned to this port are of subtype '-O'). The value of 'unknown' indicates that the port has no assigned BCEs yet or that the assigned BCEs are not of the same side (subTypeBCEMismatch). This object maps to the WT-157 attribute aGroupEnd.

Number of BCEs that is currently aggregated by the local GBS (assigned to the G.Bond port using ifStackTable). This number is never greater than sheGBondCapacity. This object SHALL be automatically incremented or decremented when a BCE is added or deleted to/from the G.Bond port using sheGbondPortStackTable. This object maps to the WT-157 attribute aGroupNumChannels

This notification indicates that the G.Bond port' upstream data rate has reached/dropped below or exceeded the low upstream rate threshold, specified by sheGBondThreshLowUpRate. This notification MAY be send for the -O subtype ports while the port is up, on the crossing event in both directions: from normal (rate is above the threshold) to low (rate equals the threshold or below it) and from low to normal. This notification is not applicable to the -R subtypes. It is RECOMMENDED that a small debouncing period of 2.5 sec, between the detection of the condition and notification, is implemented to prevent simultaneous LinkUp/LinkDown and sheGBondLowUpRateCrossing notifications to be sent. The adaptive nature of the G.Bond technology allows the port to adapt itself to the changes in the copper environment, e.g. an impulse noise, alien crosstalk or a micro-interruption may temporarily drop one or more BCEs in the aggregation group, causing a rate degradation of the aggregated G.Bond link. The dropped BCEs would then try to re-initialize, possibly at a lower rate than before, adjusting the rate to provide required target SNR margin. Generation of this notification is controlled by the sheGBondLowRateCrossingEnable object.
