PTOPO-MIB.mib object view, vendor RFC

Introduction

Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2019 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers). This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.

ActiveXperts Network Monitor 2019 can import MIB file PTOPO-MIB and use it to monitor vendor specific OID's.

PTOPO-MIB file content

Object view of PTOPO-MIB:

Scalar Object
ptopoConnEntry .1.3.6.1.2.1.79.1.1.1.1
Information about a particular physical network connection. Entries may be created and deleted in this table, either manually or by the agent, if a physical topology discovery process is active.
ptopoLastChangeTime .1.3.6.1.2.1.79.1.2.1
The value of sysUpTime at the time a conceptual row is created, modified, or deleted in the ptopoConnTable. An NMS can use this object to reduce polling of the ptopoData group objects.
ptopoConnTabInserts .1.3.6.1.2.1.79.1.2.2
The number of times an entry has been inserted into the ptopoConnTable.
ptopoConnTabDeletes .1.3.6.1.2.1.79.1.2.3
The number of times an entry has been deleted from the ptopoConnTable.
ptopoConnTabDrops .1.3.6.1.2.1.79.1.2.4
The number of times an entry would have been added to the ptopoConnTable, (e.g., via information learned from a topology protocol), but was not because of insufficient resources.
ptopoConnTabAgeouts .1.3.6.1.2.1.79.1.2.5
The number of times an entry has been deleted from the ptopoConnTable because the information timeliness interval for that entry has expired.
ptopoConfigTrapInterval .1.3.6.1.2.1.79.1.3.1
This object controls the transmission of PTOPO notifications. If this object has a value of zero, then no ptopoConfigChange notifications will be transmitted by the agent. If this object has a non-zero value, then the agent must not generate more than one ptopoConfigChange trap-event in the indicated period, where a 'trap-event' is the transmission of a single notification PDU type to a list of notification destinations. If additional configuration changes occur within the indicated throttling period, then these trap- events must be suppressed by the agent. An NMS should periodically check the value of ptopoLastChangeTime to detect any missed ptopoConfigChange trap-events, e.g. due to throttling or transmission loss. If notification transmission is enabled, the suggested default throttling period is 60 seconds, but transmission should be disabled by default. If the agent is capable of storing non-volatile configuration, then the value of this object must be restored after a re-initialization of the management system.
ptopoConfigMaxHoldTime .1.3.6.1.2.1.79.1.3.2
This object specifies the desired time interval for which an agent will maintain dynamic ptopoConnEntries. After the specified number of seconds since the last time an entry was verified, in the absence of new verification (e.g., receipt of a topology protocol message), the agent shall remove the entry. Note that entries may not always be removed immediately, but may possibly be removed at periodic garbage collection intervals. This object only affects dynamic ptopoConnEntries, i.e. for which ptopoConnIsStatic equals 'false(2)'. Static entries are not aged out. Note that dynamic ptopoConnEntries may also be removed by the agent due to the expired timeliness of learned topology information (e.g., timeliness interval for a remote port expires). The actual age-out interval for a given entry is defined by the following formula: age-out-time = min(ptopoConfigMaxHoldTime, <entry-specific hold-time>) where <entry-specific hold-time> is determined by the discovery algorithm, and may be different for each entry.
Tabular Object
ptopoConnTimeMark .1.3.6.1.2.1.79.1.1.1.1.1
A TimeFilter for this entry. See the TimeFilter textual convention in RFC 2021 to see how this works.
ptopoConnLocalChassis .1.3.6.1.2.1.79.1.1.1.1.2
The entPhysicalIndex value used to identify the chassis component associated with the local connection endpoint.
ptopoConnLocalPort .1.3.6.1.2.1.79.1.1.1.1.3
The entPhysicalIndex value used to identify the port component associated with the local connection endpoint.
ptopoConnIndex .1.3.6.1.2.1.79.1.1.1.1.4
This object represents an arbitrary local integer value used by this agent to identify a particular connection instance, unique only for the indicated local connection endpoint. A particular ptopoConnIndex value may be reused in the event an entry is aged out and later re-learned with the same (or different) remote chassis and port identifiers. An agent is encouraged to assign monotonically increasing index values to new entries, starting with one, after each reboot. It is considered unlikely that the ptopoConnIndex will wrap between reboots.
ptopoConnRemoteChassisType .1.3.6.1.2.1.79.1.1.1.1.5
The type of encoding used to identify the chassis associated with the remote connection endpoint. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnRemoteChassis .1.3.6.1.2.1.79.1.1.1.1.6
The string value used to identify the chassis component associated with the remote connection endpoint. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnRemotePortType .1.3.6.1.2.1.79.1.1.1.1.7
The type of port identifier encoding used in the associated 'ptopoConnRemotePort' object. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnRemotePort .1.3.6.1.2.1.79.1.1.1.1.8
The string value used to identify the port component associated with the remote connection endpoint. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnDiscAlgorithm .1.3.6.1.2.1.79.1.1.1.1.9
An indication of the algorithm used to discover the information contained in this conceptual row. A value of ptopoDiscoveryLocal indicates this entry was configured by the local agent, without use of a discovery protocol. A value of { 0 0 } indicates this entry was created manually by an NMS via the associated RowStatus object.
ptopoConnAgentNetAddrType .1.3.6.1.2.1.79.1.1.1.1.10
This network address type of the associated ptopoConnNetAddr object, unless that object contains a zero length string. In such a case, an NMS application should ignore any returned value for this object. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnAgentNetAddr .1.3.6.1.2.1.79.1.1.1.1.11
This object identifies a network address which may be used to reach an SNMP agent entity containing information for the chassis and port components represented by the associated 'ptopoConnRemoteChassis' and 'ptopoConnRemotePort' objects. If no such address is known, then this object shall contain an empty string. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnMultiMacSASeen .1.3.6.1.2.1.79.1.1.1.1.12
This object indicates if multiple unicast source MAC addresses have been detected by the agent from the remote connection endpoint, since the creation of this entry. If this entry has an associated ptopoConnRemoteChassisType and/or ptopoConnRemotePortType value other than 'portIdMacAddr(3)', then the value 'notUsed(1)' is returned. Otherwise, one of the following conditions must be true: If the agent has not yet detected any unicast source MAC addresses from the remote port, then the value 'unknown(2)' is returned. If the agent has detected exactly one unicast source MAC address from the remote port, then the value 'oneAddr(3)' is returned. If the agent has detected more than one unicast source MAC address from the remote port, then the value 'multiAddr(4)' is returned.
ptopoConnMultiNetSASeen .1.3.6.1.2.1.79.1.1.1.1.13
This object indicates if multiple network layer source addresses have been detected by the agent from the remote connection endpoint, since the creation of this entry. If this entry has an associated ptopoConnRemoteChassisType or ptopoConnRemotePortType value other than 'portIdGenAddr(4)' then the value 'notUsed(1)' is returned. Otherwise, one of the following conditions must be true: If the agent has not yet detected any network source addresses of the appropriate type from the remote port, then the value 'unknown(2)' is returned. If the agent has detected exactly one network source address of the appropriate type from the remote port, then the value 'oneAddr(3)' is returned. If the agent has detected more than one network source address (of the same appropriate type) from the remote port, this the value 'multiAddr(4)' is returned.
ptopoConnIsStatic .1.3.6.1.2.1.79.1.1.1.1.14
This object identifies static ptopoConnEntries. If this object has the value 'true(1)', then this entry is not subject to any age-out mechanisms implemented by the agent. If this object has the value 'false(2)', then this entry is subject to all age-out mechanisms implemented by the agent. This object may not be modified if the associated ptopoConnRowStatus object has a value of active(1).
ptopoConnLastVerifyTime .1.3.6.1.2.1.79.1.1.1.1.15
If the associated value of ptopoConnIsStatic is equal to 'false(2)', then this object contains the value of sysUpTime at the time the conceptual row was last verified by the agent, e.g., via reception of a topology protocol message, pertaining to the associated remote chassis and port. If the associated value of ptopoConnIsStatic is equal to 'true(1)', then this object shall contain the value of sysUpTime at the time this entry was last activated (i.e., ptopoConnRowStatus set to 'active(1)').
ptopoConnRowStatus .1.3.6.1.2.1.79.1.1.1.1.16
The status of this conceptual row.
Table
ptopoConnTable .1.3.6.1.2.1.79.1.1.1
This table contains one or more rows per physical network connection known to this agent. The agent may wish to ensure that only one ptopoConnEntry is present for each local port, or it may choose to maintain multiple ptopoConnEntries for the same local port. Entries based on lower numbered identifier types are preferred over higher numbered identifier types, i.e., lower values of the ptopoConnRemoteChassisType and ptopoConnRemotePortType objects.
Trap
ptopoConfigChange .1.3.6.1.2.1.79.2.0.1
A ptopoConfigChange notification is sent when the value of ptopoLastChangeTime changes. It can be utilized by an NMS to trigger physical topology table maintenance polls. Note that transmission of ptopoConfigChange notifications are throttled by the agent, as specified by the 'ptopoConfigTrapInterval' object.
