Point-to-Point Protocol {{bibref|RFC1661}}. This object contains the {{object|Interface}} table. {{numentries}} The Network Control Protocols (NCPs) that are supported by the device. {{enum}} Note that {{enum|IPv6CP}} is an IPv6 capability. AppleTalk Control Protocol {{bibref|RFC1378}} {{bibref|RFC1332}} {{bibref|RFC1552}} {{bibref|RFC2097}} {{bibref|RFC5072}} PPP interface table (a stackable interface object as described in {{bibref|TR-181i2|Section 4.2}}). Enables or disables the interface. This parameter is based on ''ifAdminStatus'' from {{bibref|RFC2863}}. The current operational state of the interface (see {{bibref|TR-181i2|Section 4.2.2}}). {{enum}} When {{param|Enable}} is {{false}} then {{param}} SHOULD normally be {{enum|Down}} (or {{enum|NotPresent}} or {{enum|Error}} if there is a fault condition on the interface). When {{param|Enable}} is changed to {{true}} then {{param}} SHOULD change to {{enum|Up}} if and only if the interface is able to transmit and receive network traffic; it SHOULD change to {{enum|Dormant}} if and only if the interface is operable but is waiting for external actions before it can transmit and receive network traffic (and subsequently change to {{enum|Up}} if still operable when the expected actions have completed); it SHOULD change to {{enum|LowerLayerDown}} if and only if the interface is prevented from entering the {{enum|Up}} state because one or more of the interfaces beneath it is down; it SHOULD remain in the {{enum|Error}} state if there is an error or other fault condition detected on the interface; it SHOULD remain in the {{enum|NotPresent}} state if the interface has missing (typically hardware) components; it SHOULD change to {{enum|Unknown}} if the state of the interface can not be determined for some reason. This parameter is based on ''ifOperStatus'' from {{bibref|RFC2863}}. The textual name of the interface as assigned by the CPE. The accumulated time in {{units}} since the interface entered its current operational state. {{list}} {{reference|an interface object that is stacked immediately below this interface object}} See {{bibref|TR-181i2|Section 4.2.1}}. Current status of the connection. The cause of failure for the last connection setup attempt. The time in {{units}} since the establishment of the connection after which connection termination is automatically initiated by the CPE. This occurs irrespective of whether the connection is being used or not. A value of 0 (zero) indicates that the connection is not to be shut down automatically. The time in {{units}} that if the connection remains idle, the CPE automatically terminates the connection. A value of 0 (zero) indicates that the connection is not to be shut down automatically. Time in {{units}} the {{param|ConnectionStatus}} remains in the {{enum|PendingDisconnect|ConnectionStatus}} state before transitioning to disconnecting state to drop the connection. Username to be used for authentication. Password to be used for authentication. Describes the PPP encryption protocol. Describes the PPP compression protocol. {{bibref|RFC1332}} {{bibref|RFC1974}} Describes the PPP authentication protocol. The maximum allowed size of frames sent from the remote peer. The current MRU in use over this connection. Trigger used to establish the PPP connection. {{enum}} Note that the reason for a PPP connection becoming disconnected to begin with might be either external to the CPE, such as termination by the BRAS or momentary disconnection of the physical interface, or internal to the CPE, such as use of the {{param|IdleDisconnectTime}} and/or {{param|AutoDisconnectTime}} parameters in this object. If this PPP connection is disconnected for any reason, it is to remain disconnected until the CPE has one or more packets to communicate over this connection, at which time the CPE automatically attempts to reestablish the connection. If this PPP connection is disconnected for any reason, the CPE automatically attempts to reestablish the connection (and continues to attempt to reestablish the connection as long it remains disconnected). If this PPP connection is disconnected for any reason, it is to remain disconnected until the user of the CPE explicitly instructs the CPE to reestablish the connection. A PPP LCP Echo Request is sent every {{param}} {{units}}. A value 0 means that no LCP Echo Requests are sent. {{bibref|RFC1661|5.8 Echo-Request and Echo-Reply}} describes the relevant LCP Echo frames. Applicable only when {{param|LCPEcho}} is greater than 0. When number of consecutive {{param}} LCP Echo Replies have been missed. The remote peer will be assumed dead and the connection will be terminated. When traffic is received during the {{param|LCPEcho}} interval, no LCP Echo-Request is sent until the next {{param|LCPEcho}} interval. Enables or disables IPCP ({{bibref|RFC1332}}) on this interface. If this parameter is present, {{enum|IPCP|#.SupportedNCPs}} MUST be included in {{param|#.SupportedNCPs}}. Enables or disables IPv6CP ({{bibref|RFC5072}}) on this interface. If this parameter is present, {{enum|IPv6CP|#.SupportedNCPs}} MUST be included in {{param|#.SupportedNCPs}}. PPPoE object that functionally groups PPPoE related parameters. PPPoE is only applicable when the lower layer provides Ethernet frames, e.g. ATM with EoA, PTM, or anything else that supports an Ethernet MAC. Represents the PPPoE Session ID. PPPoE Access Concentrator. PPPoE Service Name. IP Control Protocol (IPCP) client object for this PPP interface {{bibref|RFC1332}}. {{object}} only applies to IPv4. The local IPv4 address for this connection received via IPCP. The remote IPv4 address for this connection received via IPCP. {{list}} Items represent DNS Server IPv4 address(es) received via IPCP {{bibref|RFC1877}}. If {{false}}, the PPP Interface retrieved information is configured on the IP Interface stacked on top of this PPP Interface. If {{true}}, the PPP Interface retrieved information is propagated to the parameters in the referenced {{param|PassthroughDHCPPool}} object, replacing any existing configuration (including ''MinAddress'', ''MaxAddress'', ''SubnetMask'', ''IPRouters'', and ''DNSServers''). {{reference}}When {{param}} is set to {{empty}}, {{param|PassthroughEnable}} MUST be set to {{false}} (i.e. passthrough can not be enabled without a pool reference specified). IPv6 Control Protocol (IPv6CP) client object for this PPP interface {{bibref|RFC5072}}. {{object}} only applies to IPv6. The interface identifier for the local end of the PPP link, negotiated using the IPv6CP ''Interface-Identifier'' option {{bibref|RFC5072|Section 4.1}}. The identifier is represented as the rightmost 64 bits of an IPv6 address (the leftmost 64 bits MUST be zero and MUST be ignored by the recipient). The interface identifier for the remote end of the PPP link, negotiated using the IPv6CP ''Interface-Identifier'' option {{bibref|RFC5072|Section 4.1}}. The identifier is represented as the rightmost 64 bits of an IPv6 address (the leftmost 64 bits MUST be zero and MUST be ignored by the recipient). Throughput statistics for this interface. The CPE MUST reset the interface's Stats parameters (unless otherwise stated in individual object or parameter descriptions) either when the interface becomes operationally down due to a previous administrative down (i.e. the interface's {{param|#.Status}} parameter transitions to a down state after the interface is disabled) or when the interface becomes administratively up (i.e. the interface's {{param|#.Enable}} parameter transitions from {{false}} to {{true}}). Administrative and operational interface status is discussed in {{bibref|TR-181i2|section 4.2.2}}. The total number of bytes transmitted out of the interface, including framing characters. The total number of bytes received on the interface, including framing characters. The total number of packets transmitted out of the interface. The total number of packets received on the interface. The total number of outbound packets that could not be transmitted because of errors. The total number of inbound packets that contained errors preventing them from being delivered to a higher-layer protocol. The total number of packets requested for transmission which were not addressed to a multicast or broadcast address at this layer, including those that were discarded or not sent. The total number of received packets, delivered by this layer to a higher layer, which were not addressed to a multicast or broadcast address at this layer. The total number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space. The total number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being delivered. One possible reason for discarding such a packet could be to free up buffer space. The total number of packets that higher-level protocols requested for transmission and which were addressed to a multicast address at this layer, including those that were discarded or not sent.
