What Is ACC-SMDS?

ACC-SMDS is an enterprise MIB for ACC/Ericsson routers covering SMDS (Switched Multimegabit Data Service) interface configuration, including address settings and traffic statistics for SMDS WAN circuits. It exposes objects for SMDS address configuration (individual and group addresses) and interface traffic counters covering packets/bytes sent and received and errors. Its monitoring value is in tracking SMDS circuit health and utilization: traffic and error counters reveal whether an SMDS link is carrying expected volume or experiencing packet loss/errors, a direct signal of a degrading WAN circuit. It would typically be used alongside a standard interface MIB (IF-MIB) for generic interface state and ACC-ALARMS for fault notifications on the same interface. The ACC-SMDS MIB is deployed on ACC/Ericsson routers connecting to legacy SMDS-based public WAN services.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACC-SMDS. 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 polls the SMDS interface traffic counters to confirm throughput matches expected levels for a subscribed access rate, and checks the address configuration objects to verify the correct individual/group addresses are assigned. A rising error counter alongside falling successful-packet counts would indicate a degrading SMDS circuit or address misconfiguration causing dropped traffic.

OIDs

OID symbolic	OID numeric	Type	Access	Description
accSipL3Entry	1.3.6.1.4.1.5.1.1.26.2.1		not-accessible	This list contains SIP L3 parameters and state variables.
CTR accSipL3Errors	1.3.6.1.4.1.5.1.1.26.2.1.8	Counter	read-only	The total number of SIP Level 3 PDUs received from the remote system that were discovered to have errors (including protocol processing and bit errors but excluding addressing-related errors) and were discarded. Includes both group addressed L3PDUs and L3PDUs containing an individual destination address.
INT accSipL3Index	1.3.6.1.4.1.5.1.1.26.2.1.1	INTEGER	read-only	The value of this object identifies the SIP port interface for which this entry contains management information. The value of this object for a particular interface has the same value as the ifIndex object, defined in RFC 1156 and RFC 1213, for the same interface.
CTR accSipL3InvAddrs	1.3.6.1.4.1.5.1.1.26.2.1.9	Counter	read-only	The number of SIP Level 3 PDUs received from the remote system that had the Source or Destination Address_Type subfields, (the four most significant bits of the 64 bit address field), not equal to the value 1100 or 1110. Also, an error is considered to have occurred if the Address_Type field for a Source Address, the four most significant bits of the 64 bits, is equal to 1110 (a group address).
CTR accSipL3RcvGAs	1.3.6.1.4.1.5.1.1.26.2.1.3	Counter	read-only	The total number of group addressed SIP Level 3 PDUs received from the remote system across the SNI. The total includes only unerrored L3PDUs.
CTR accSipL3RcvIAs	1.3.6.1.4.1.5.1.1.26.2.1.2	Counter	read-only	The total number of individually addressed SIP Level 3 PDUs received from the remote system across the SNI. The total includes only unerrored L3PDUs.
CTR accSipL3SndGAs	1.3.6.1.4.1.5.1.1.26.2.1.7	Counter	read-only	The number of group addressed SIP L3PDUs that have been sent by this system across the SNI.
CTR accSipL3SndIAs	1.3.6.1.4.1.5.1.1.26.2.1.6	Counter	read-only	The number of individually addressed SIP Level 3 PDUs that have been sent by this system across the SNI.
accSipL3Table	1.3.6.1.4.1.5.1.1.26.2		not-accessible	This table contains SIP L3 parameters and state variables, one entry per SIP port.
CTR accSipL3UnkGAs	1.3.6.1.4.1.5.1.1.26.2.1.5	Counter	read-only	The number of SIP Level 3 PDUs received from the remote system with invalid or unknown group addresses. (Destination Address Screening violations are not included). See SMDS Subscription MIB module.
CTR accSipL3UnkIAs	1.3.6.1.4.1.5.1.1.26.2.1.4	Counter	read-only	The number of SIP Level 3 PDUs received from the remote system with invalid or unknown individual destination addresses (Destination Address Screening violations are not included). See SMDS Subscription MIB module.
accSMDS	1.3.6.1.4.1.5.1.1.26
accSmdsPortEntry	1.3.6.1.4.1.5.1.1.26.1.1		not-accessible	This list contains SMDS port parameters and state variables.
ADR accSmdsPortIA	1.3.6.1.4.1.5.1.1.26.1.1.2	SmdsAddress	read-write	The value of this object specifies the SNI Individual address configured for this SIP interface port.
INT accSmdsPortIndex	1.3.6.1.4.1.5.1.1.26.1.1.1	INTEGER	read-only	The value of this object identifies the SIP port interface for which this entry contains management information. The value of this object for a particular interface has the same value as the ifIndex object, defined in RFC 1156 and RFC 1213, for the same interface.
INT accSmdsPortPollingStatus	1.3.6.1.4.1.5.1.1.26.1.1.3	INTEGER	read-write	The administrative status of heartbeat polling for this SMDS port. ON enables the generation of heartbeat polls, and OFF disables it. Note: the status of this object does not affect the response to heartbeat polls received. We always respond to polls received.
accSmdsPortTable	1.3.6.1.4.1.5.1.1.26.1		not-accessible	This table contains SMDS port parameters and state variables, one entry per SMDS port.
