HDSL2-SHDSL-LINE-MIB: View SNMP OID List / Download MIB

This MIB module defines a collection of objects for managing HDSL2/SHDSL lines. An agent may reside at either end of the line; however, the MIB module is designed to require no management communication between the modems beyond that inherent in the low-level EOC line protocol as defined in ANSI T1E1.4/2000-006 (for HDSL2 lines) or in ITU G.991.2 (for SHDSL lines). Copyright (C) The Internet Society (2005). This version of this MIB module is part of RFC 4319; see the RFC itself for full legal notices.

This table supports overall configuration of HDSL2/SHDSL spans. Entries in this table MUST be maintained in a persistent manner.

This object provisions the number of repeaters/regenerators in this HDSL2/SHDSL span.

This object is a pointer to a span configuration profile in the hdsl2ShdslSpanConfProfileTable, which applies to this span. The value of this object is the index of the referenced profile in the hdsl2ShdslSpanConfProfileTable. Note that span configuration profiles are only applicable to SHDSL lines. HDSL2 lines MUST reference the default profile, 'DEFVAL'. By default, this object will have the value 'DEFVAL' (the index of the default profile). Any attempt to set this object to a value that is not the value of the index for an active entry in the profile table, hdsl2ShdslSpanConfProfileTable, MUST be rejected.

This object is a pointer to an alarm configuration profile in the hdsl2ShdslEndpointAlarmConfProfileTable. The value of this object is the index of the referenced profile in the hdsl2ShdslEndpointAlarmConfProfileTable. The alarm threshold configuration in the referenced profile will be used by default for all segment endpoints in this span. Individual endpoints may override this profile by explicitly specifying some other profile in the hdsl2ShdslEndpointConfTable. By default, this object will have the value 'DEFVAL' (the index of the default profile). Any attempt to set this object to a value that is not the value of the index for an active entry in the profile table, hdsl2ShdslEndpointAlarmConfProfileTable, MUST be rejected.

This table provides overall status information of HDSL2/SHDSL spans. This table contains live data from equipment. As such, it is NOT persistent.

This table supports retrieval of unit inventory information available via the EOC from units in an HDSL2/SHDSL line. Entries in this table are dynamically created during the line discovery process. The life cycle for these entries is as follows: - xtu discovers a device, either a far-end xtu or an xru - an inventory table entry is created for the device - the line goes down for whatever reason - inventory table entries for unreachable devices are destroyed As these entries are created/destroyed dynamically, they are NOT persistent.

An entry in the hdsl2ShdslInventoryTable. Each entry represents inventory information for a single unit in an HDSL2/SHDSL line. It is indexed by the ifIndex of the HDSL2/SHDSL line and the Hdsl2ShdslUnitId of the associated unit.

An entry in the hdsl2ShdslEndpointConfTable. Each entry represents a single segment endpoint in an HDSL2/SHDSL line. It is indexed by the ifIndex of the HDSL2/SHDSL line, the UnitId of the associated unit, the side of the unit, and the wire pair of the associated modem.

The side of the unit associated with this segment endpoint -- Network/Customer side -- as per the Hdsl2ShdslUnitSide textual convention.

The wire pair of the modem associated with this segment endpoint as per the Hdsl2ShdslWirePair textual convention.

This object configures the alarm threshold values to be used for this segment endpoint. The values are obtained from the alarm configuration profile referenced by this object. The value of this object is the index of the referenced profile in the hdsl2ShdslEndpointAlarmConfProfileTable, or NULL (a zero-length SnmpAdminString). If the value is a zero-length SnmpAdminString, the endpoint uses the default Alarm Configuration Profile for the associated span as per the hdsl2ShdslSpanConfAlarmProfile object in the hdsl2ShdslSpanConfTable. The default value of this object is a zero-length SnmpAdminString. Any attempt to set this object to a value that is not the value of the index for an active entry in the profile table, hdsl2ShdslEndpointAlarmConfProfileTable, MUST be rejected.
