Description: Manages ATM service registry for LECS and other ATM services on Cisco ATM switches.

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 CISCO-ATM-SERVICE-REGISTRY-MIB?

CISCO-ATM-SERVICE-REGISTRY-MIB is a Cisco enterprise MIB for ATM (Asynchronous Transfer Mode) switches that exposes the ILMI Service Registry, a mechanism used by ATM devices to advertise and discover services such as the LAN Emulation Configuration Server (LECS). It provides configuration and read-only data about registered services, their ports, ATM addresses, and service identifiers on a per-port basis. This MIB is used mainly for configuration visibility rather than hardware/software health monitoring, though an administrator can use it to confirm that expected ATM services are correctly registered and reachable on a given switch port, which indirectly reflects the operational status of ATM signaling software. It builds on ATM Forum ILMI conventions and Cisco's ATM switch software architecture rather than a general IETF standard. It is typically deployed in legacy Cisco ATM switch fabrics where LAN Emulation or other ATM services need to be dynamically discovered by attached devices. Engineers can download the CISCO-ATM-SERVICE-REGISTRY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ATM-SERVICE-REGISTRY-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 would poll asrSrvcRegTable (indexed via asrSrvcRegEntry by port and asrSrvcRegServiceID) to see which services, such as LECS, are registered on a given ATM port, along with asrSrvcRegATMAddress showing the address clients should use to reach that service. If asrSrvcRegRowStatus shows an entry as not active, or an expected service ID/address pairing is missing, that indicates the service was never registered or was removed, which would break ATM client bootstrap. This is primarily a configuration/discovery table rather than a performance-counter table.

What Can Be Monitored

registered ATM service entries
service ID to ATM address mapping
port-level service registration
row status of service registry entries

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoAtmServiceRegistryMIB	1.3.6.1.4.1.9.9.50			A MIB module to allow an NMS to monitor and configure the information which an ATM switch makes available via the ILMI's Service Registry Table.
ciscoAtmServiceRegistryMIBObjects	1.3.6.1.4.1.9.9.50.1
asrSrvcRegTable	1.3.6.1.4.1.9.9.50.1.1		not-accessible	The table implemented by an ATM switch to allow monitoring and control of the ATM addresses of registered services which it makes avaiable to ATM end-systems via the ILMI across its UNIs.
asrSrvcRegEntry	1.3.6.1.4.1.9.9.50.1.1.1		not-accessible	Information about a single service provider that is to be made available to the user-side of one or more ATM UNIs. An entry, for which asrSrvcRegPort has a non-zero value, is a specific assignment to that UNI; an entry for which asrSrvcRegPort is zero applies to all UNIs for which this table contains no specific assignments.
NUM asrSrvcRegPort	1.3.6.1.4.1.9.9.50.1.1.1.1	InterfaceIndexOrZero	not-accessible	Either the value 0, or the ifIndex value of an the ATM Interface. A row for which this object has a non-zero value is a specific assignment to that UNI; a row for which this object is zero applies to all UNIs for which this table contains no specific assignments. Some switches may only support this object with the value of zero.
OID asrSrvcRegServiceID	1.3.6.1.4.1.9.9.50.1.1.1.2	OBJECT IDENTIFIER	not-accessible	The service identifier which uniquely identifies the type of service at the address given by the corresponding value of asrSrvcRegATMAddress. Specific values for this identifier are defined in the ILMI specification (e.g., asrSrvcRegLecs) or elsewhere.
ATM asrSrvcRegATMAddress	1.3.6.1.4.1.9.9.50.1.1.1.3	AtmAddr	read-create	An ATM address to which the ATM end-system on this UNI can attempt to establish a connection for the service.
I32 asrSrvcRegAddressIndex	1.3.6.1.4.1.9.9.50.1.1.1.4	Integer32	not-accessible	An arbitrary integer to differentiate multiple rows containing different ATM addresses for the same service on the same UNI.
OCT asrSrvcRegParm1	1.3.6.1.4.1.9.9.50.1.1.1.5	OCTET STRING	read-create	An octet string used according to the value of asrSrvcRegServiceID.
ROW asrSrvcRegRowStatus	1.3.6.1.4.1.9.9.50.1.1.1.6	RowStatus	read-create	The status of this row. No object in the row can be modified while the value of this object is 'active'.
asrSrvcRegMIBConformance	1.3.6.1.4.1.9.9.50.3
asrSrvcRegMIBCompliances	1.3.6.1.4.1.9.9.50.3.1
asrSrvcRegMIBCompliance	1.3.6.1.4.1.9.9.50.3.1.1			The compliance statement for ATM switches which implement the Cisco Service Registry MIB
asrSrvcRegMIBGroups	1.3.6.1.4.1.9.9.50.3.2
asrSrvcRegMIBGroup	1.3.6.1.4.1.9.9.50.3.2.1			A collection of objects providing monitoring and control of ATM addresses of services which an ATM switch is to make available via the ILMI.
