What Is APPIAN-TRUNK-PPP-MIB?

APPIAN-TRUNK-PPP-MIB is a vendor-specific MIB from Appian Communications covering PPP and Multilink PPP (MLPPP) trunk-level services, complementing the logical-port PPP MIB by managing bundled/trunked PPP links on Appian's access platforms. It exposes trunk configuration such as negotiated MRU/MRRU, sequence numbering, magic number and LCP echo settings, management access, and IPCP address negotiation for each PPP trunk bundle. Its monitoring focus is software/protocol status: acPppTrunkLCPEchoEnable and acPppTrunkLCPEchoInterval reveal whether keepalive monitoring is active on the bundle, and acPppTrunkMaxTerminate indicates the termination retry threshold used to detect a failed link before tearing it down. It shares its underlying node/index addressing scheme with the other Appian PPP MIBs in the same family. It is used on Appian OSAP access-transport platforms that aggregate multiple physical circuits into a single logical MLPPP trunk for capacity and resiliency. Engineers can download the APPIAN-TRUNK-PPP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in APPIAN-TRUNK-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.

Monitoring Examples

An administrator polling acPppTrunkTable via acPppTrunkIndex would check acPppTrunkLCPEchoEnable and acPppTrunkLCPEchoInterval to confirm keepalive monitoring is configured as expected on a trunk bundle, since a disabled echo can mask a silently failed member link. Comparing negotiated acPppTrunkMru/acPppTrunkMrru against expected values helps catch a peer that dropped multilink support. acPppTrunkSeqNum trending can reveal packet-sequencing anomalies within the bundle, and acPppTrunkIPCPAddressEnable confirms whether IP address negotiation is active on the trunk.

What Can Be Monitored

trunk LCP echo/keepalive status
negotiated MRU/MRRU
trunk sequence numbering
IPCP address negotiation state
trunk termination retry threshold

TruthValue

OIDs

OID symbolic	OID numeric	Type	Access	Description
acPppTrunk	1.3.6.1.4.1.2785.2.6.3			Appian Communications PPP/MLPPP Services MIB.
acPppTrunkTable	1.3.6.1.4.1.2785.2.6.3.1		not-accessible	A table containing PPP-link specific configuration information. This table is created, with reasonable defaults, whenever the associated acTrunkTable acTrunkProt field is set to 'PPP' or 'MLPPP'. Managment of this record is required only when it is desired to change the reasonable default.
acPppTrunkEntry	1.3.6.1.4.1.2785.2.6.3.1.1		not-accessible	Configuration information about a particular PPP Link.
INT acPppTrunkIndex	1.3.6.1.4.1.2785.2.6.3.1.1.1	INTEGER	accessible-for-notify	The trunk entry that this PPP / MLPPP configuration is associated.
INT acPppTrunkMru	1.3.6.1.4.1.2785.2.6.3.1.1.2	INTEGER	read-write	This attribute has been deprecated - it no longer has an effect.
INT acPppTrunkMrru	1.3.6.1.4.1.2785.2.6.3.1.1.3	INTEGER	read-write	This attribute has been deprecated - it no longer has an effect.
INT acPppTrunkSeqNum	1.3.6.1.4.1.2785.2.6.3.1.1.4	INTEGER	read-write	Defines the type of multilink sequence number to use. There are two possible sequence number types: long and short. Long sequence numbers are 24 bit values. Short sequence numbers are 12 bit values. The default is the PPP standard of long sequence numbers
T/F acPppTrunkMagicNumberEnable	1.3.6.1.4.1.2785.2.6.3.1.1.5	TruthValue	read-write	Enables the inclusion of magic numbers in LCP messages. This, in conjunction with LCP echo is useful to detect non-transitory loopback conditions. This feature defaults to enabled (True).
T/F acPppTrunkLCPEchoEnable	1.3.6.1.4.1.2785.2.6.3.1.1.6	TruthValue	read-write	Enables the OSAP initiation of LCP Echo message sequence processing. This attribute also controls link keepalive processing which is based upon LCP echo processing. This feature defaults to enabled (True).
INT acPppTrunkLCPEchoInterval	1.3.6.1.4.1.2785.2.6.3.1.1.7	INTEGER	read-write	Time in seconds between OSAP initiated echo sequences. The default is 60 seconds. The range is an integer which is expressed in seconds supporting 1 second to 1 hour in length. This value has a direct relationship to how long it takes to detect a PPP link down condition via keepalive processing. The lower this value the quicker a PPP link down condition will be detected. The default for this value is 1
T/F acPppTrunkMgmtAccess	1.3.6.1.4.1.2785.2.6.3.1.1.8	TruthValue	read-write	This attribute controls how a PPP trunk starts up. It is used to indicate if this is an inband managment trunk. TRUE indicates the trunk can be exclusively used for inband managment. FALSE indicates the trunk is a data trunk only. A PPP trunk can not be used for inband managment and data passing at the same time. The default for this attribute is FALSE
T/F acPppTrunkIPCPAddressEnable	1.3.6.1.4.1.2785.2.6.3.1.1.9	TruthValue	read-write	This attribute controls if IP address negotiation occurs during the IPCP phase of a PPP trunk startup. If this attribute is set to TRUE the IP address negotiation will occur. If this attribute is set to FALSE then IP address negotiation will not occur. The default for this attribute will be FALSE
INT acPppTrunkMaxTerminate	1.3.6.1.4.1.2785.2.6.3.1.1.10	INTEGER	read-write	Max-Terminate indicates the number of Terminate-Request packets sent without receiving a Terminate-Ack before assuming that the peer is unable to respond.
INT acPppTrunkMaxConfigure	1.3.6.1.4.1.2785.2.6.3.1.1.11	INTEGER	read-write	Max-Configure indicates the number of Configure-Request packets sent without receiving a valid Configure-Ack, Configure-Nak or Configure-Reject before assuming that the peer is unable to respond.
INT acPppTrunkMaxFailure	1.3.6.1.4.1.2785.2.6.3.1.1.12	INTEGER	read-write	Max-Failure indicates the number of Configure-Nak packets sent without sending a Configure-Ack before assuming that configuration is not converging.
