Description: Manages Zhone Technologies PPP link configuration, authentication credentials, and LCP/NCP negotiation.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ZHONE-COM-PPP-MIB?

ZHONE-COM-PPP-MIB is a Zhone Technologies enterprise MIB, from the same IP Software lineage in Minneapolis, MN, for managing Point-to-Point Protocol (PPP) links on Zhone access equipment, covering link configuration, authentication credentials, and LCP/NCP negotiation state. It exposes PPP link status alongside authentication settings such as PAP/CHAP and the negotiated Link/Network Control Protocol parameters for each PPP session. Its monitoring value is centered on software/link status: administrators poll LCP/NCP negotiation state to confirm a PPP link has come up cleanly, and check authentication status to catch a failed login that would prevent a subscriber or backhaul link from establishing. It implements the IETF PPP standard (RFC 1661 and related LCP/NCP RFCs) as its underlying protocol dependency. It is deployed on Zhone broadband/access equipment terminating PPP or PPPoE sessions from subscriber or backhaul connections, as modeled by the ZHONE-COM-PPP-MIB MIB.

IPNetwork Monitor allows you to monitor SNMP objects defined in ZHONE-COM-PPP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Zhone broadband/access equipment (PPP/PPPoE termination)

Monitoring Examples

An administrator would poll the PPP link's LCP/NCP negotiation state to confirm a session has successfully reached the Network-layer-up phase, and check the authentication status object to see whether PAP/CHAP authentication succeeded or is repeatedly failing for a given subscriber line. Repeated authentication failures on the same link would point to a credential mismatch on the CPE side. Because no sample objects were captured for this MIB, exact object/table names cannot be confirmed beyond what the short description indicates.

OIDs

OID symbolic	OID numeric	Type	Access	Description
pppInterfaceTable	1.3.6.1.4.1.5504.4.5.1		not-accessible	This table is used to configure attributes of a PPP interface that are not currently covered by the standard MIBs. This table is indexed by the ifIndex of the PPP interface. IANA iftype ppp is #23.
pppInterfaceEntry	1.3.6.1.4.1.5504.4.5.1.1		not-accessible	There is an entry in this table for every provisioned PPP interface. Rows are created by setting pppIfRowStatus to createAndGo(4). Rows are removed by setting pppIfRowStatus to destroy(6). When a row is created or deleted in this table, a row is also created or deleted in the pppLCPExtensionsTable in this MIB module and the pppLinkConfigTable and pppLqrConfigTable in RFC 1471. An entry will also be created/destroyed in the ifTable (RFC2233). The pppIfLowerIfIndex is required for row creation.
NUM pppIfLowerIfIndex	1.3.6.1.4.1.5504.4.5.1.1.1	InterfaceIndex	read-create	The ifIndex of the lower layer interface to which this PPP interface should be bound. Since PPP interfaces are always statically bound, this value can never be zero. Upon setting this field, the ifStack will be modified to reflect the appropriate binding. This object is required for row creation.
OID pppIfVpi	1.3.6.1.4.1.5504.4.5.1.1.2	AtmVpIdentifier	read-create	If this IP interface is on an ATM VC, the ATM VPI is specified here. If the IP interface is not an ATM VC, this field is ignored. The VPI value for a VPL or VCL. The value VPI=0 is only allowed for a VCL. For ATM UNIs supporting VPCs the VPI value ranges from 0 to 255. The VPI value 0 is supported for ATM UNIs conforming to the ATM Forum UNI 4.0 Annex 8 (Virtual UNIs) specification. For ATM UNIs supporting VCCs the VPI value ranges from 0 to 255. For ATM NNIs the VPI value ranges from 0 to 4095. The maximum VPI value cannot exceed the value allowable by atmInterfaceMaxActiveVpiBits defined in ATM-MIB.
OID pppIfVci	1.3.6.1.4.1.5504.4.5.1.1.3	AtmVcIdentifier	read-create	If this PPP interface is on an ATM VC, the ATM VCI is specified here. If the PPP interface is not an ATM VC, this field is ignored. The maximum VCI value cannot exceed the value allowable by atmInterfaceMaxActiveVciBits defined in ATM-MIB.
INT pppIfCallMode	1.3.6.1.4.1.5504.4.5.1.1.4	INTEGER	read-create	Indicates where the PPP call is initiated. noCall: No call is initiated inCall: Call is intiated remotely. outCall: Call is intiated locally.
INT pppIfFrameType	1.3.6.1.4.1.5504.4.5.1.1.5	INTEGER	read-create	The type of framing used if the link type is ATM or Frame Relay. If link type is atm, pppIfFrameType must be atmLLC or atmVc. If link type is frameRelay, pppIfFrameType must be frameRelay. If link type is any other value, pppIfFrameType must be none. Currently, only atmLLC and atmVC are supported.

ZHO pppIfRowStatus	1.3.6.1.4.1.5504.4.5.1.1.7	ZhoneRowStatus	read-create	Zhone convention to support row creation and deletion. pppIfLgId is required to create or destroy a row in this table.
pppLCPExtensionsTable	1.3.6.1.4.1.5504.4.5.2		not-accessible	This table is used to configure attributes not found in the pppLinkConfigTable defined in RFC 1471. This table is indexed by the ifIndex of the PPP interface to which these LCP attributes apply.
pppLCPExtensionsEntry	1.3.6.1.4.1.5504.4.5.2.1		not-accessible	There is an entry in this table for every provisioned PPP interface. Rows in this table are created or deleted when a row in the pppInterfaceTable is created or deleted using pppIfRowStatus. Therefore, objects in this table cannot be set in the same SNMP PDU as the objects used to create a row in the pppInterfaceTable.

U32 lcpExtMagicNumber	1.3.6.1.4.1.5504.4.5.2.1.7	Unsigned32	read-create	The number used in Magic Number negotiation. Magic number negotiation must be enabled using pppLinkConfigMagicNumber in RFC1471. When set to zero, a random number will be used for the magic number. This allows us to better prevent having two devices with the same magic number.
I32 lcpExtMaxPad	1.3.6.1.4.1.5504.4.5.2.1.8	Integer32	read-create	The number of padded bytes at the end of data.

Rows are created by setting ipIfPppEnabled in the ipInterfaceTable to 'true'. Rows are deleted by setting ipIfPppEnabled in the ipInterfaceTable to 'false'. Creating or deleting a row in this table will do the same in the pppIpConfigTable in rfc1473.mib.

A single subscriber may have multiple authenticated users. If this entry is only used for outgoing authentication, there may not be an associated subscriber. Therefore, the subId may be zero.

OCT pppAuthCHAPSecret	1.3.6.1.4.1.5504.4.5.5.1.9	OCTET STRING	read-create	The password used if we are authenticating with the CHAP protocol. Default value is the empty string. For security, an empty string will be returned on a GET.
INT pppAuthStatus	1.3.6.1.4.1.5504.4.5.5.1.10	INTEGER	read-create	Setting this object to 'invalid' causes the information for that entry to become invalidated. Calls using the authentication information from an invalidated entry will not be accepted or initiated. This allows an entry to be temporarily disabled without deleting it from the table.
