Index
Correlating PPP interface index.
BodMode
Enables bandwidth on demand (BOD) mode for leased line and dialup interfaces when setting to bod-active (3) respectively bod-passive (4) or backup only mode for leased line connections like X.21. bod-reduce-incoming (12) reduces the number of links on incoming connections if needed/wanted. When set to disabled (1), neither bandwidth on demand (as specified by the pppExtIfTable) or backup mode is enabled. Four modes (bap-active (5), bap-passive (6), bap-both(7) and bap-first (8)) are available for BAP (Bandwidth Allocation Protocol) support to specify wether BAP Call-Requests and BAP Callback-Requests should be initiated and/or accepted.

Enumerations:

  • disabled (1)
  • backup (2)
  • bod-active (3)
  • bod-passive (4)
  • bap-active (5)
  • bap-passive (6)
  • bap-both (8)
  • bap-first (9)
  • bap-client (10)
  • bap-server (11)
  • bod-reduce-incoming (12)
Algorithm
The algorithm to use for weighting line utilization. Line utilization is determined by calculating the average load for each interface. When set to equal (1) all samples taken over the time interval (defined in pppExtIfInterval) will be given equal weight, when set to proportional (2) the weighting disproportional to the age of the sample.

Enumerations:

  • equal (1)
  • proportional (2)
Interval
The time interval (in seconds) to use for sampling and calculating of the average throughput of the interface. See also: pppExtIfLoad.

Range: 5 to 300

Load
The actual throughput (in percent) of the total bandwidth of this interface (load). This value is updated once every second and based on the amount of traffic during the last sampling interval. Note that only the actual maximum of the both directions (send / receive) is considered.

Range: 0 to 100

MlpFragmentation
The multilink PPP fragmentation mode. When set to proportional (1) packets will be divided into fragments proportional to the transmission rate of each link, when set to equal (2) packets will be divided into multiple equal fragments (equal to MlpFragSize) such that the number sent on each link is proportional to the transmission rate. When set to interleave (3), large datagrams will be fragmentated (maximum size determined by MlpFragSize) to reduce transmission delay of high-priority traffic on slower links.

Enumerations:

  • proportional (1)
  • equal (2)
  • interleave (3)
MlpFragSize
The multilink PPP fragment size. If MlpFragmentation is set to proportional (1) this value specifies the minimum size of the fragment in bytes. If MlpFragmentation is set to equal (2) this value specifies the maximum fragment size in bytes.

Range: 30 to 1500

PPPoEService
The PPPoE (PPP over Ethernet, RFC 2516) service name which indicates the requested service during PPPoE discovery stage. Examples of the use of the service name are to indicate an ISP name or a class or a quality of service.

Length: 0 to 63

PPPoEAcServer
The PPPoE (PPP over Ethernet, RFC 2516) AC-Server name which determines the access concentrator during PPPoE discovery stage.

Length: 0 to 63

EncKeyNegotiation
This variable defines the specification of shared secrets (encryption keys) between the sender and receiver of encrypted data. If set to static (1), the keys specified in 'pppExtIfEncTxKey' and 'pppExtIfEncRxKey' will be used, if set to authentication (2), the key derivation is based on PPP authentication via CHAP or MS-CHAP.

Enumerations:

  • static (1)
  • authentication (2)
EncTxKey
Static (encryption) key used for transmission of encrypted data via PPP. It's size depends on the used encryption algorithm and the corresponding key length, e.g. 'des_56' or 'blowfish_168'.
EncRxKey
Static (decryption) key used for decryption of encrypted data received on PPP connections. It's size depends on the used encryption algorithm and the corresponding key length, e.g. 'des_56' or 'blowfish_168'.
GearUpThreshold
Gear up threshold for invoking current bandwidth. The measured throughput (in percent of the total bandwidth) of this interface (see pppExtIfLoad) is compared with this value once per second. If exceeded longer than 5 seconds an additional B-channel will be requested.

Range: 0 to 100

GearDownThreshold
Gear down threshold for decreasing current bandwidth. The expected throughput (in percent of the total bandwidth) of this interface (see pppExtIfLoad) after dropping a B-channel is compared with this threshold value once per second. If the needed bandwidth falls below this threshold longer than 10 seconds, exactly one B-channel will be dropped.

Range: 0 to 100

AodiDChanQlen
Upper threshold for the amount of data (in octets) waiting to be sent across the 9.6Kbit/sec D-channel. If exceeded, additional bandwidth will be invoked at once.
AodiGearDownTxRate
Lower threshold for the amount of data in bits per second to be sent across the 64Kbit/sec B-channel. If the measured throughput becomes smaller than this value over a period of pppExtIfGearDownPersistance seconds, the remaining B-channel will be dropped.
GearUpPersistance
Gear up persistence interval for invoking current bandwidth. The measured throughput (in percent of the total bandwidth) of this interface (see pppExtIfLoad) is compared with the current value of the variable pppExtIfGearUpThreshold once per second. If exceeded longer than pppExtIfGearUpPersistance seconds an additional B-channel will be requested.

Range: 0 to 100

GearDownPersistance
Gear down persistence interval for decreasing current bandwidth. The measured throughput (in percent of the total bandwidth) of this interface (see pppExtIfLoad) is compared with the current value of pppExtIfGearDownThreshold once per second. If exceeded longer than pppExtIfGearDownPersistance seconds, exactly one B-channel will be dropped.

Range: 0 to 100

L1Speed
This object contains the interface's nominal bandwidth in bits per second. Please note that this parameter may not represent the real available transmission rate. The current purpose is only informational for example for PPTP or PPPoE interfaces where no accurate information from the underlaying network is available.
CurrentRetryTime
Current time in seconds to wait before retrying a call when the smart retry algorithm is implemented.

Range: 0 to 36000

MaxRetryTime
Maximum time in seconds to wait before retrying a call when the smart retry algorithm is implemented. When set to zero this algorithm is disabled.

Range: 0 to 36000

Mtu
Determines size of the largest datagram which can be sent on the interface, specified in octets (see ifMtu). When set to zero (default), the value of the variable ifMtu depends on the received LCP MRU/MRRU option.

Range: 0 to 8192

Mru
The maximum length for the PPP information field, including padding, but not including the protocol field, is termed the Maximum Receive Unit (MRU).

Range: 0 to 8192

AuthMutual
This object enables mutual PPP authentication between the peers.

Enumerations:

  • disabled (1)
  • enabled (2)
DialProfileIndex

DialinL1Protocol
This variable determines the permitted layer 1 protocol for incoming calls. If set to all(31) there is no specific restriction. In all other cases incoming calls are either rejected (when identified via CLID) or terminated after identification via PPP authentication (inband authentication) if the used layer 1 protocol doesn't match. Note that this check will be also performed for any initial call used to initiate a callback.

RadiusMarkAcct
Determines wether start or stop of RADIUS accounting should be marked (via Accounting-On/Accounting-Off) for the logical RADIUS server group specified by pppExtIfRadiusGroupId. RADIUS 'Accounting-On' is send either if set to trigger-on (3) or once the associated IPCP layer reaches the operational 'up' statuis. RADIUS 'Accounting-Off' is send either if set to trigger-off (4) or once the associated IPCP layer reaches the operational 'down' status.
