Description: Defines ATM Forum automatic configuration objects for ILMI-based device discovery and address assignment.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is ATM-FORUM-AUTO-CONFIG?
ATM-FORUM-AUTO-CONFIG is a vendor-neutral MIB defined by the ATM Forum for ILMI-based automatic configuration of ATM devices, covering address assignment and discovery at the UNI. It exposes configuration/discovery state - such as whether auto-configuration succeeded and what address or prefix was assigned - rather than hardware sensor data. Its monitoring use is limited to confirming that plug-and-play address configuration completed correctly on an ATM interface, which is a software/config-status concern rather than a physical health one. It depends directly on the ATM Forum's ILMI (Interim Local Management Interface) and UNI signalling standards. It is deployed on ATM switches and edge devices that rely on automatic UNI address configuration rather than manual provisioning. Engineers can download the ATM-FORUM-AUTO-CONFIG file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-FORUM-AUTO-CONFIG. 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.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- ATM switch/edge device
Monitoring Examples
No object names were supplied for this MIB. Conceptually, an operator would check an interface's auto-configuration status object to confirm address assignment completed, and inspect the assigned ATM address/prefix to verify it matches the expected addressing plan for that UNI.
What Can Be Monitored
- ILMI auto-configuration status
- assigned ATM address/prefix

However, if no user plane layer 3 protocol is specified, then the first (and only) octet shall be encoded as '0b00000000'. a) If ISO TR9577 network layer protocol identification is to be used, then the first octet shall be encoded to indicate 'ISO/IEC TR9577'. In this case, either: i) the user plane layer 3 protocol is to be selected in the management plane. The second octet of this object shall contain the ISO/IEC TR9577 Initial Protocol Identifier (IPI). - For layer 3 protocols for which ISO/IEC has assigned a Network Layer Protocol Identifier (NLPID), then this NLPID shall be used as the IPI, and the length of the octet string shall be 2. - For layer 3 protocols for which ISO/IEC has not assigned an NLPID, the IPI shall be encoded to indicate 'IEEE 802.1a SNAP identifier' (see Annex D of ISO/IEC 9577). The following five octets (octets 3 through 7) of this object shall then contain a SNAP identifier, which consists of a 3-octet organization unique identifier (OUI) and a 2-octet protocol identifier (PID). This SNAP coding shall be used only if ISO/IEC has not assigned a Network Layer Protocol Identifier for the layer 3 or layer 2 protocol. The octet string shall thus be 7 octets long. - If an IME wishes to indicate that bridged LAN frames are to be carried in the user plane then the IPI shall be encoded to indicate 'IEEE 802.1a SNAP identifier'. The following five octets of this object shall contain a SNAP identifier, which indicates the bridged protocol. For consistency with SIG 4.0, use of the ISO/IEC subsequent protocol identifier (SPI) is not recommended but not explicitly prohibited as one can envision scenarios where it has utility. or ii) the user plane layer 3 protocol is to be selected using network layer protocol identification in the user plane. The octet-string shall be one octet long. The first octet(s) of each layer 3 protocol data unit shall contain layer 3 protocol identification according to ISO/IEC TR9577. b)If bits 0-4 of the first octet of the octet string are set to any value other than 'ISO/IEC TR9577', then any subsequent octets shall be encoded as follows. Bit 7 (i.e., the most significant bit) of each of these octets shall be set to 0; however, if it is set to 1, it shall be ignored. Bits 0-6 shall be encoded according to the codings for octet 7a, octet 7b and octet 7c specified in table 4- 10/Q.2931. If more than one subsequent octet is needed, then octets shall appear in the order shown in figure 4-16/Q.2931. |

The semantics of the value of this object is PHY and/or MAC specific. This semantics generally shall be specified with the PHY or MAC. However, the semantics for the two PHY/MAC specifications which have been identified as having multiple connections is provided here for convenience: When the physical layer is dual latency ADSL, the PhyMacIdentifier selects the latency path to be bound to each direction of transmission for the PVC. The value of the PhyMacIdentifier shall be as follows: default = 0 upstream and downstream both interleaved path = 1 upstream and downstream both fast path = 2 upstream interleaved path, downstream fast path = 3 upstream fast path, downstream interleaved path = 4 The 'default' value shall be used for single latency ADSL PHYs. When the physical and MAC layers are IEEE 802.14, the PhyMacIdentifier specifies the 802.14 Local Identifier for the PVC |
