Bestie, if you want the full tea on the current Internet-Standard Management Framework docs, check section 7 of RFC 3410 [RFC3410] 📚
Managed objects live in a virtual information store called the Management Information Base, or MIB 🧚 You usually reach them through the Simple Network Management Protocol (SNMP). Objects in the MIB get defined using the mechanisms in the Structure of Management Information (SMI). This memo gives you a MIB module that's compliant to SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580] 💅
2. Overview 🦋
The whole point of this memo is to add capabilities that aren't in the ATM-MIB [RFC2515], and you need those to manage ATM interfaces 🔥 It covers these areas:
- ATM Switch Support
- ATM Service Support
- ATM Host Support
Plus, this memo also brings ATM trap support 🔔
2.1. Background 📖
Okay so there are other MIB modules you need too if you want to manage ATM interfaces, links, and cross-connects 🌈 Some examples are MIB II for general system and interface management ([RFC2863]), the DS3 ([RFC2496]) or SONET MIBs ([RFC3592]) for managing SONET and DS3 physical interfaces, and, where it makes sense, MIB modules for apps that use ATM, like SMDS [RFC1694] and LAN Emulation [ATM Forum LANE]. Those are outside the scope of this spec, so no spoilers here 🙈
This MIB module also needs the ATM-MIB module defined in [RFC2515], plus the ATM-specific textual conventions defined in [RFC2514] 💖
ATM Endpoint applications, like ATM LAN Emulation or Classical IP-over-ATM Clients and Servers, use ATM to set up SVC/PVC connections for swapping control and data info ✨ The agents of these ATM applications must provide the network manager with info on the SVC/PVCs in use and on which applications are using them. The info can be made generic so it applies to all ATM applications. This memo defines extensions to the ATM-MIB [RFC2515] to support that 🫶
The current spec of this supplemental ATM2-MIB is based on SNMPv2 SMI 🎀
2.2. Important Definitions 💜
These terms are defined here and used all through this MIB:
- Virtual Path Link (VPL)
- Virtual Path Connection (VPC)
- Virtual Path Segment (VP Segment)
- Virtual Channel Link (VCL)
- Virtual Channel Connection (VCC)
- Virtual Channel Segment (VC Segment).
The figures below show how these terms show up in typical ATM network topologies 🦋 More terms relevant to this MIB are defined and illustrated in the ATM Terminology section 3 of [RFC2515] 🌸

3.1.1. ATM SVC VP Cross-Connect Table ✨
okay so this table is the SVC VP Cross-Connect (SVPC) info, bestie 🦋 The PVC version lives in [RFC2515], and this one also covers cross-connect info for Soft PVPs 💜
This table holds the configuration and state info for every SVC VP cross-connect, whether it's point-to-point, point-to-multipoint, or multipoint-to-multipoint 🌸
It's read-only for monitoring the cross-connects that link the VPLs together inside an ATM switch or network. The atmSvcVpCrossConnectIndex is what ties together the SVC VPLs that are cross-connected. The atmSvcVpCrossConnectRowStatus object is read-write so you can tear things down 💅
Here's the vibe: each bi-directional SVC VP cross-connect is modelled as a set of entries in the atmSvcVpCrossConnectTable. A point-to-point VPC cross-connect is just one entry. A point-to-multipoint one with N leafs takes N entries, and a multipoint-to-multipoint one with N parties takes N(N-1)/2 entries. In those last two cases, all the entries share the same atmSvcVpCrossConnectIndex value, so they all belong to one cross-connect 🧚
_________________________________________
| |
Low | ATM Switch or Network | High
port| | port
_____|>> from low to high VPC traffic flow >>|______
|<< from high to low VPC traffic flow <<|
|_______________________________________|Figure 3: VPC Cross-Connect Model
So "low" and "high" are just numerical ordering 🔥 The ATM interface with the lower ifIndex value is 'low', and the other ATM interface on that VPC cross-connect is 'high'.
3.1.2. ATM SVC VC Cross-Connect Table 🎀
This one is the SVC Cross-Connect (SVCC) info. The PVC version is also in [RFC2515], and this table includes cross-connect info for Soft PVCs too 🌈
It models a bi-directional point-to-point, point-to-multipoint, or multipoint-to-multipoint SVC VC cross-connect 🦋
It's read-only as well, and you use it to watch the cross-connects that link the VCLs together inside an ATM switch or network, the ones that belong to a VC connection. The atmSvcVcCrossConnectIndex ties the related SVC VCLs together, and atmSvcVcCrossConnectRowStatus is read-write for tear-down ✨
Same deal as before: each bi-directional SVC VC cross-connect is a set of entries in the atmSvcVcCrossConnectTable. Point-to-point is one entry, point-to-multipoint with N leafs is N entries, and multipoint-to-multipoint with N parties is N(N-1)/2 entries. In the last two, they all share one atmSvcVcCrossConnectIndex value 💜
______________________________________

Low | ATM Switch or Network | High
port| | port
_____|>> from low to high VC traffic flow >>|______
|<< from high to low VC traffic flow <<|
|______________________________________|Figure 4: VC Cross-Connect Model
Low and high work the exact same way here. The ATM interface with the lower ifIndex is 'low', and the other one on the VPC cross-connect is 'high' 🍓
3.1.3. ATM Interface Signalling Statistics Table 📊
This table is all about the stats for the signalling entity. A signalling entity can run over an ATM interface from the atmInterfaceConfTable [RFC2515], over a logical ATM interface (see section 5.1.10.1 in this doc), or over a proprietary virtual interface from the atmInterfaceExtTable. To keep an eye on it, there are a bunch of counters:
atmSigSSCOPConEvents
atmSigSSCOPErrdPdus
atmSigDetectSetupAttempts
atmSigEmitSetupAttempts
atmSigDetectUnavailRoutes
atmSigEmitUnavailRoutes
atmSigDetectUnavailResrcs
atmSigEmitUnavailResrcs
atmSigDetectCldPtyEvents
atmSigEmitCldPtyEvents
atmSigDetectMsgErrors
atmSigEmitMsgErrors
atmSigDetectClgPtyEvents
atmSigEmitClgPtyEvents
atmSigDetectTimerExpireds
atmSigEmitTimerExpireds
atmSigDetectRestarts
atmSigEmitRestarts
atmSigInEstabls
atmSigOutEstabls3.1.4. ATM Signalling Capability Support 🔍
Not every Information Element is supported by every ATM switch or ATM Service, so for trouble isolation it's really important to track which ones are supported 🙈 The matching group of objects must be supported by switches or services that support SVCs, and it shows whether each of these Information Elements is enabled or disabled:
- Calling party number
- Calling party subaddress
- Called party subaddress
- Broadband high layer information
- Broadband low layer information
- Broadband Repeat Indicator
- AAL parameters
The last one, Preferred Carrier Pre-Subscription, tells you which carrier intercarrier calls from this interface get routed to when the calling party doesn't give transit network selection info 💅
3.1.5. Signalling Descriptor Parameter Table 🌸
This table extends the ATM VCL table from the ATM-MIB [RFC2515] to add all the other signalling info that's specified in the ATM Forum UNI Specifications [ATM Forum 3.0] and [ATM Forum UNI 3.1]. You can create an entry with all the signalling parameters and then reuse it to set the signalling characteristics of SVCs 🎀
Some signalling parameters, like the AAL5 parameters information element, already show up in the VCL and VPL tables. So this table only holds the remaining AAL5 parameters ✨
Signalling attributes fall into these categories:
- ATM Adaptation Layer Parameters
This info lives in the ATM Signalling Descriptor Parameter Table in this memo. Check section 5.4.5.5 of [ATM Forum 3.0] and [ATM Forum UNI 3.1] 🧚
- Broadband High Layer Information
This info lives in the ATM Signalling Descriptor Parameter Table in this memo. Check section 5.4.5.8 of [ATM Forum 3.0] and [ATM Forum UNI 3.1] 🦋
- Broadband Low Layer Information
This info lives in the ATM Signalling Descriptor Parameter Table in this memo. Check section 5.4.5.9 of [ATM Forum 3.0] and [ATM Forum UNI 3.1] 💜
3.1.6. ATM Interface Registered Address Table 📮
This table is a list of ATM addresses that a switch or service can use for calls to and from a given interface. The addresses are either registered by the endsystem via ILMI or set up statically. Heads up: this table doesn't expose PNNI reachability info. It only applies to switches and network services. See also Section 5.2 🌈
3.1.7. ATM VPI/VCI to Address Mapping Table 🗺️
In the atmVclAddrTable, atmVclAddrAddr can be either an ATM Local Address or an ATM Remote Address. Together they're the two endpoint addresses of a VCL. The ATM Local Address identifies the local endpoint of the VCL that this agent represents. The ATM Remote Address is the address of the ATM application at the other end of the VCL 🍓
3.1.8. ATM Address to VPI/VCI Mapping Table 🔁
This table is another way to get at the atmVclTable. You can use it to look up the atmVclTable index using an ATM address 💖
3.1.9. ATM VPL Statistics Table 📈
The atmVplStatTable has per-VPL cell counters. These count the valid ATM cells, which means user and OAM cells. They leave out physical layer cells (like idle cells) and unassigned cells 🫶
Incoming cells get counted differently depending on their Cell Loss Priority: CLP=0 (high) or CLP=1 (low). The "traffic policing" entity in the ATM managed system tags, passes, or discards cells based on the incoming CLP value and the policed cell rate. For the details on traffic policing, check [ATM Forum 3.0] and [ATM Forum UNI 3.1] 👑
On a switch that doesn't do traffic policing, cells are passed or discarded based on the bandwidth and buffering capacity of the switching fabric. In that case the Output Tagged Cells counter is always zero 💀
_______________
| ATM Managed |
Input | System | Output
CLP=0 cells| | CLP=0 cells
---------->| |----------->
CLP=1 cells| (traffic | CLP=1 cells
---------->| policing |----------->
| entity) | Tagged cells (CLP=1)
|_____________|----------->
|Discard | Discard
|CLP=0 | CLP=1

V VFigure 5: ATM Cell Counters per VPL
In this table, cells going into and out of the managed ATM system get counted as a total and as CLP=0 cells. The CLP=1 counter is worked out by subtracting the CLP=0 cells from the total. Cells that get tagged on the output are counted too. So the output CLP=1 cells equal the total outgoing cells minus both the CLP=0 cells and the tagged cells 🌟
3.1.10. ATM VPL Logical Port Table 🔌
The ATM VPL Logical Port Table holds all the config info for ATM logical port interfaces 🎀
3.1.10.1. ATM Logical Port Interface ✨
okay so the interface type "ATM Logical Port" (ifType=80) exists so we can represent a VP Tunnel 🦋. A VP Tunnel is a VPL used as a trunk connection, usually between devices that aren't physically adjacent, and it gives you multiplexing and demultiplexing of VCs on the VP. Figure 6 shows one and it's giving main character energy 💅
Quick note, bestie: the "ATM Logical Port" is more of a logical port, while an interface of type "ATM" is more of a physical port. The physical one carries lots of VP and VC connections between adjacent devices.
<------VP Tunnel------>

O OFigure 6: Virtual Path Tunnel
In Figure 6, the VP tunnel is called VPL1 by Switch A and VPL2 by Switch B 🧚. It connects VCL1 with VCL4, and VCL2 with VCL3. The figure only shows one VP tunnel, but there can be multiple VP tunnels over the same physical interface 🫶
A super useful VP tunnel scenario is tunneling across a public network that doesn't support signalling 🌈. In Figure 6, imagine Switches A and B are private switches that signal over the VP to set up connections transparently through the public network. The public network just transports a PVC VP between the two switches.
Because the VP Tunnel is an interface between two ATM devices that aren't necessarily physically adjacent, most of the management information for the interface can be different for the tunnel, including:
- active VPI/VCI fields (the tunnel may be a subset of the parent interface).
- maximum number of VCCs
- configured VCCs
- ILMI VPI/VCI values
- ATM address type
- ATM administrative address
- received/transmitted cells.
3.1.10.2. How to create an ATM Logical Port interface 🎀
On ATM devices that support VP tunnels, the ATM Logical Port Interface Table can be used to create VP tunnels. To create an ATM Logical Port interface via SNMP, do the following:
- Create a VPL (e.g., VPI=a on an existing ATM interface which has ifIndex=x) in the
atmVplTable. - Set the object
atmVplLogicalPortDeftoisLogicalIf. The agent then creates a new row in the ifTable, with ifIndex=y, to represent the ATM Logical Port interface. The agent also sets the objectatmVplLogicalPortIndexto y, which is the ifIndex value of the ATM Logical Port interface. - Set the ifEntry values for the ATM Logical Port interface (ifIndex=y) as discussed in RFC 2515, with the following exceptions:
- ifType - a new enumerated value of
atmLogical(80)was added to IANAifType, specifying an "ATM Logical Port" interface. - ifSpeed - the total bandwidth in bits per second for use by the ATM layer, computed from the traffic descriptor for the VPL.
- ifOperStatus - determined hierarchically, depending on the state of the physical atm-cell layer interface beneath it, and the ILMI on the VP.
- ifInOctets, ifOutOctets - support of these objects is not mandatory for ATM Logical Port interfaces.
- ifInErrors - always zero, since HEC errors are specified for the atm cell-layer interface beneath it.
- ifInUnknownProtos - always zero, since errors are specified for the atm cell-layer interface beneath it.
- ifType - a new enumerated value of
- The atmInterfaceConfEntry values are set and reported as discussed in [RFC2515], with the following exceptions:
- atmInterfaceMaxVpcs - 0.
- atmInterfaceConfVpcs - 0.
- atmInterfaceIlmiVpi - VPI of the VP tunnel.
- The atmInterfaceExtEntry values are set and reported as follows:
- atmInterfaceConfMaxSvpcVpi - VPI of the VP tunnel, although VPCs cannot be set up on a VP tunnel.
- atmInterfaceCurrentMaxSvpcVpi - VPI of the VP tunnel, although VPCs cannot be set up on a VP tunnel.
- atmInterfaceConfMaxSvccVpi - VPI of the VP tunnel.
- atmInterfaceCurrentMaxSvccVpi - VPI of the VP tunnel.
- atmIntfPvcFailures - includes failures of PVCLs within the VP tunnel, but not of the PVPL itself, since those are reported on the atm(37) interface.
- atmIntfCurrentlyFailingPVpls - 0.
- atmIntfPvcFailuresTrapEnable - enables traps for PVCL failures within the VP tunnel, but not for the PVPL itself, since the latter are generated on behalf of the atm(37) interface.
- An entry is created in the ifStackTable, with ifStackHigherLayer=y and ifStackLowerLayer=x.
- VCLs defined on the VP tunnel are indexed by ifIndex=y, VPI=a, and VCI.
3.1.11. ATM VCL Statistics Table 📊
The atmVclStatTable includes per-VCL cell counters. These count the valid ATM cells, which means the user and OAM cells, but not the physical layer cells (e.g., idle cells) or the unassigned cells. Cells coming into an ATM managed system are counted differently depending on whether CLP=0 (high Cell Loss Priority) or CLP=1 (low Cell Loss Priority). Depending on the incoming CLP value and the policed cell rate, the "traffic policing" entity in the ATM managed system tags, passes or discards the cells. For a description of traffic policing, see [ATM Forum 3.0] and [ATM Forum UNI 3.1] 🔍
In a switch where traffic policing isn't supported, cells are passed or discarded depending on the bandwidth and buffering capacity of the switching fabric. In that case, the Output Tagged Cells counter is always zero 🙈

| ATM Managed |
Input | System | Output
CLP=0 cells| | CLP=0 cells
---------->| |----------->
CLP=1 cells| (traffic | CLP=1 cells

V VFigure 7: ATM Cell Counters per VCL
In this table, the cells coming into and going out of the managed ATM system are counted as a total number of cells, and as cells with CLP=0. The CLP=1 counter is worked out by subtracting the CLP=0 cells from the total cells. Cells that are tagged on the output are also counted. So the output CLP=1 cells equal the total cells out count minus both the CLP=0 cells and the tagged cells. Math with main character energy 🧮
3.1.12. ATM VC General Information Table 💜
This table holds the general information for each VC. It provides an index to the atmSigDescrParamTable defined in this MIB. It's an extension to the atmVclTable defined in the ATM-MIB [RFC2515] 🌸
3.1.13. ATM Interface Configuration Extension Table 🍓
The ATM Interface Configuration Extension Table holds ATM interface information that supplements the atmInterfaceConfTable defined in [RFC2515]. It includes the configuration information for the interface type (i.e., connection setup procedures) and ILMI.
A network manager can configure the interface to run a specific type of connection setup procedure (i.e., protocol and version), such as ITU-T DSS2, ATM Forum UNI 3.1, PNNI 1.0 or BICI 2.0. The manager can also decide the role of the managed entity as one side of the interface. For example, if an interface is configured to run ATM Forum UNI 3.1, the managed entity has to be told whether to run as the network side or the user side of the UNI 👑
The objects atmIntfConfigType and atmIntfConfigSide are used for configuration, and the objects atmIntfActualType and atmIntfActualSide are used for reading back the actual interface protocol and version.
The following table describes all the valid combinations of interface type and side. The value N/A means not applicable, and it should be set to the value other(1) when used.
atmIntfConfigType atmIntfConfigSide
----------------- -----------------
autoConfig N/A
ituDss2 user/network
atmfUni3Dot0 user/network
atmfUni3Dot1 user/network
atmfUni4Dot0 user/network
atmfIispUni3Dot0 user/network
atmfIispUni3Dot1 user/network
atmfIispUni4Dot0 user/network
atmfPnni1Dot0 N/A
atmfBici2Dot0 N/A
atmfUniPvcOnly user/network
atmfNniPvcOnly N/AWhen atmIntfConfigType is set to autoConfig(2), the interface type is determined via the ATM Forum ILMI auto-configuration procedures [ATM Forum ILMI]. There's no need to set the interface side, since it should be a derived value. The PNNI and BICI interfaces are always symmetric, so setting the interface side isn't necessary for them either 🤖
This table also includes the configured and negotiated maximum VPI value per ATM interface, and the configured and negotiated minimum VCI value per ATM interface. For a detailed description, refer to [ATM Forum ILMI] Sections 8.2.3.8 through 8.2.3.10 📖
The following figure shows how the current minimum VCI values are derived from the configured minimum VCI values and the neighbouring minimum VCI values 🦋
+--------+ +--------+ +--------+
| ATM | ifA ifB | ATM | ifC ifD | ATM |
| Device |--------------| Device |--------------| Device |
+--------+ +--------+ +--------+
ifA: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 40 (negotiated)
ifB: Configured Min SVCC VCI = 40 (configured)
Current Min SVCC VCI = 40 (negotiated)
ifC: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 32 (negotiated)
ifD: Configured Min SVCC VCI = 32 (configured)
Current Min SVCC VCI = 32 (negotiated)Between ifA and ifB, the maximum of the two values for atmInterfaceConfMinSvccVci is 40, so both interfaces set their atmInterfaceCurrentMinSvccVci values to 40. On the other hand, since ifC and ifD are both configured with atmInterfaceConfMinSvccVci values of 32, they set their atmInterfaceCurrentMinSvccVci values to 32 ✨
Figure 8: Examples of configured vs. negotiated ILMI values
3.1.14. ATM ILMI Service Registry Table
okay so this table is basically the switch's little directory 📒 It tells ATM hosts where the important network services live, like the LAN Emulation Configuration Server (LECS), the ATM Name Server (ANS), the ATMARP Server, the Multicast Address Resolution Server (MARS), and the NHRP Server (NHS). The entries get passed to neighbouring devices over ILMI, either on all the ATM interfaces or just a few that someone picked 🦋
let's walk through an example, bestie 💖 say we have:
- An ATM switch X with three interfaces, if1, if2 and if3 🌸
- Two ATM network services, a1.a2...aN and b1.b2...bN. Those are object identifiers that name each service, so a1.a2...aN names the first one and b1.b2...bN names the other one ✨
- The first service is at the ATM address 'a' 🎀
- The second service is at the ATM address 'b' 🎀
- Any device connected to switch X can use the first service 👑
- Only devices plugged into if1 and if3 on switch X can use the second service 🔥
+------------------+ +------------------+
|service a1.a2...aN| |service b1.b2...bN|

Figure 9: ATM topology with registered servicesso switch X's table ends up with three entries 💅
- one entry for "a1.a2...aN", which is implicitly available to any device on switch X
- two entries for "b1.b2...bN", one for each interface where that service can be explicitly used
the content looks like this:
- Service Identifier: a1.a2...aN b1.b2...bN b1.b2...bN
- ATM address: a b b
- Arbitrary index: m n p
- Available interface: 0 1 3quick decoder ring 🔑 the service IDs are stored in atmIlmiSrvcRegServiceID, the ATM addresses a and b are in atmIlmiSrvcRegATMAddress, and the values m, n and p are arbitrary non-zero integers. They're there so the two b1.b2...bN entries (both sitting at ATM address 'b') can be told apart. Those live in atmIlmiSrvcRegAddressIndex. Last one: the available interfaces go in atmIlmiSrvcRegIndex, and the special value 0 means "any ATM interface" 🧚
and when a device queries this table over ILMI, here's what it gets 🫶
- the device on if1 gets address a and b 💜
- the device on if2 gets address a only 🌈
- the device on if3 gets address a and b ✨
3.1.15. ILMI Network Prefix Table
this table holds the network prefix(es) the network side of the UNI hands out on each interface during ILMI address registration 🌸 if no prefixes are set for a particular interface, then one or more prefixes based on the switch address(es) may be used for that ILMI address registration 🦋
3.1.16. ATM Switch Address Table
this one holds one or more ATM endsystem addresses for each switch 💖 those addresses are how you identify the switch 🔥 and if no ILMI network prefixes are configured on certain interfaces, prefixes based on the switch address(es) may be used for ILMI address registration 🎀
3.1.17. AAL5 per-VCC Statistics Table
this table is all the AAL5 statistics for the VCCs 📊 💅
3.1.18. ATM VP Cross-Connect Extension Table
this one extends the atmVpCrossConnectTable, which is defined in ATM-MIB [RFC2515] ✨
3.1.19. ATM VC Cross-Connect Extension Table
same energy as the last one, but this time it extends the atmVcCrossConnectTable, also defined in ATM-MIB [RFC2515] 🦋
3.1.20. Currently Failing PVPL Table
this table lists every PVPL that's in trouble right now 😭
3.1.21. Currently Failing PVCL Table
and this one lists every PVCL that's in trouble 💀
3.1.22. Leaf Initiated Join Counter support
two counter objects get added here, one counting leaf initiated setup requests and one counting leaf initiated setup failures 🧚 that's how you track the leaf-side drama 👑
3.2. Network and User Addresses
so on the user side of an ATM UNI interface, there may be an address called "ifPhysAddress" that identifies the interface 🌸 there may also be several other addresses that can be used to originate and receive calls 💖 The ones used to receive calls are listed in the "ifRcvAddrTable", which is defined in RFC 2863 🎀 The registered addresses on the network side go in the ATM Registered Address Table 🦋 That table is supported by switches and network services, but hosts don't support it 💅
3.3. Configuration of VPLs, VCLs, and Cross-Connects
okay so the ATM Managed Objects you need to configure VPLs, VCLs, and Cross-Connects of the Permanent VPLs and VCLs are all defined in the ATM-MIB [RFC2515] ✨ The Cross-Connects of the Switched VPLs and VCLs, though? Those are defined in this memo 🫶
3.4. ATM-related Trap Support
traps are defined to catch changes in the status of permanent VPLs and VCLs 🔔 the current up/down status of each permanent VPL or VCL shows up in the atmVplOperStatus or atmVclOperStatus object, respectively 💜 A bunch of tables, objects and one trap are defined so network managers can spot those status changes fast and efficiently 🔥 That means you don't have to keep polling every row in the whole atmVplTable and atmVclTable, which is slow and eats resources 😭
the atmIntfPvcFailures counter and the atmIntfCurrentlyFailingPVpls and atmIntfCurrentlyFailingPVcls gauges give you a quick way to see the status of all PVPLs and PVCLs on an interface 🌈 The atmCurrentlyFailingPVplTable and the atmCurrentlyFailingPVclTable list all the problem PVPLs and PVCLs, so you can find them quickly 🧚
the atmIntfPvcFailuresTrap fires just after a PVPL or PVCL on a particular interface leaves the 'up' operational state 🚨 Managers can then read the atmCurrentlyFailingPVplTable and the atmCurrentlyFailingPVclTable to figure out which PVPLs and/or PVCLs are failing 🎀 Generating the atmIntfPvcFailuresTrap is rate limited: any trap that would happen within atmIntfPvcNotificationInterval of a previous trap for the same interface gets suppressed 🦋 Managers should keep polling the tables and objects mentioned above for at least that long if they want to keep up with what's going on in the network 💅

DESCRIPTION
"Number of Incorrect Messages transmitted on this interface.
The Incorrect Messages Counter reflects any sort of incorrect
information in a message. This includes:
- RELEASE, RELEASE COMPLETE, ADD PARTY REJECT,
and STATUS messages transmitted or
received, that contain any of the Cause values
listed below.
- Ignored messages. These messages are dropped
because the message was so damaged that it could
not be further processed. A list of dropped
messages is compiled below:
1. Message with invalid protocol discriminator
2. Message with errors in the call reference I.E.
- Bits 5-8 of the first octet not equal to
'0000'
- Bits 1-4 of the first octet indicating a
length other than 3 octets
- RELEASE COMPLETE message received with a
call reference that does not relate to a
call active or in progress
- SETUP message received with call reference
flag incorrectly set to 1
- SETUP message received with a call
reference for a call that is already
active or in progress.Ngl this emit counter is basically the detect counter's twin 👯♀️ except it counts the transmitted side too, so the same list shows up with an extra "or received" bit tacked on. Iconic copy-paste energy, but make it make sense 💖
okay so the cause code list keeps going, and this one is giving main character energy 💅✨

8. Security Considerations 🔒
Okay bestie, this section is SERIOUS 😭 Read it all, no skipping!
There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability:
Table Sensitivity/vulnerability
1. atmSvcVpCrossConnectTable Deletion of VP cross-connects
2. atmSvcVcCrossConnectTable Deletion of VC cross-connects
3. atmSigStatTable Signalling read-only statistics
4. atmSigSupportTable Signalling configuration params
5. atmSigDescrParamTable Signalling configuration params
6. atmIfRegisteredAddrTable Interface address table
7. atmVclAddrTable VCL/Address mapping table
8. atmAddrVclTable VCL/Address mapping table
(read-only)
9. atmVplStatTable VPL statistics (read-only)
10. atmVplLogicalPortTable VPL logical port configuration
11. atmVclStatTable VCL statistics (read-only)
12. atmAal5VclStatTable AAL5 statistics (read-only)
13. atmVclGenTable Signalling configuration
14. atmInterfaceExtTable Interface configuration
15. atmIlmiSrvcRegTable ILMI config params
16. atmIlmiNetworkPrefixTable ILMI config params
17. atmSwitchAddressTable Switch address info
18. atmVpCrossConnectXTable VP cross-connect params
19. atmVcCrossConnectXTable VC cross-connect params
20. atmCurrentlyFailingPVplTable PVPL status info (read-only)
21. atmCurrentlyFailingPVclTable PVCL status info (read-only)Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. 🙈
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. This is giving major risk energy 💀
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). 🔐
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them. 👑
