Description: Tracks per-BGP-peer and per-prefix traffic volume accounting statistics on Ericsson service provider router platforms.

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 ERICSSON-ROUTER-BGP-ACCOUNTING-MIB?

The ERICSSON-ROUTER-BGP-ACCOUNTING-MIB is a vendor-specific SNMP module from Ericsson for its SmartEdge/Smart Service Router (SSR) family of service-provider routers, used to implement BGP policy-based accounting. It exposes traffic accounting buckets keyed by BGP policy attributes such as community lists and AS paths, tracking inbound packet and octet counts per circuit and interface. While primarily a traffic-accounting MIB rather than a hardware-health MIB, it supports operational monitoring of software-level state -- specifically the BGP accounting subsystem's per-bucket counters, context bindings, and interface associations -- letting operators detect stalled counters, misconfigured accounting policies, or unexpected traffic volume that might signal routing or configuration faults. It builds on BGP concepts (community/AS-path based classification) and is scoped per SNMP context (community string in v1/v2c, contextName in v3), reflecting Ericsson's multi-context router architecture. It is typically deployed in service-provider networks running Ericsson SmartEdge/SSR routers where operators need granular, policy-driven billing or traffic-engineering visibility per BGP peer and circuit. Engineers can download the ERICSSON-ROUTER-BGP-ACCOUNTING-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERICSSON-ROUTER-BGP-ACCOUNTING-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 operator would poll eriRouterBpaTable/eriRouterBpaEntry, indexed by eriRouterBpaBucketIndex, to retrieve eriRouterBpaInPacketCount and eriRouterBpaInOctetCount for a given eriRouterBpaCircuitDescr and eriRouterBpaInterfaceName. A sudden flattening of these counters for a bucket that previously showed steady growth would indicate the BGP accounting bucket has stopped receiving matching traffic, possibly due to a route change or misapplied community/AS-path filter. Correlating eriRouterBpaContextName across contexts helps confirm whether the anomaly is isolated to one VRF/context or affects the whole router.

What Can Be Monitored

per-BGP-policy inbound packet counts
per-BGP-policy inbound octet counts

How to Use in IPNetwork Monitor

Example using eriRouterBpaInPacketCount OID:

Select an Ericsson SmartEdge/SM/SSR router (Redback Networks heritage) (BGP policy-based traffic accounting) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type eriRouterBpaInPacketCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of packets received for a particular bgp routing policy on an interface. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
eriRouterBgpPolAcctMIB	1.3.6.1.4.1.193.218.2.20			The BGP policy based accounting MIB defines necessary objects to account for IP traffic differentially via the BGP policies (e.g., community list, AS path). All mib objects defined in the module are viewed within the context identified in the SNMP protocol (i.e. the community string in v1/v2c or the contextName in v3).
eriRouterBgpPolAcctMIBObjects	1.3.6.1.4.1.193.218.2.20.1
eriRouterBpaTable	1.3.6.1.4.1.193.218.2.20.1.1		not-accessible	A list of BGP Policy Accounting entries
eriRouterBpaEntry	1.3.6.1.4.1.193.218.2.20.1.1.1		not-accessible	An entry contains statistics applicable to a particular bgp based routing policy set on a particular interface. The ifIndex instances referenced by this table represent a port, channel, sub-channel or circuit layer that supports the IF-MIB ifPacketGroup, ifHCPacketGroup or ifVHCPacketGroup, and is bound to an IP interface for which BGP policy based accounting is enabled. Since the IF-MIB may provide support for a subset of the physical interfaces available on the system, it follows that support for BGP policy based accounting information in this MIB is limited to the same subset of physical interfaces supported in the IF-MIB.
I32 eriRouterBpaBucketIndex	1.3.6.1.4.1.193.218.2.20.1.1.1.1	Integer32	read-only	An integer value greater than 0, that uniquely identifies a bgp routing policy set on this interface.
C64 eriRouterBpaInPacketCountEx	1.3.6.1.4.1.193.218.2.20.1.1.1.2	Counter64	read-only	The total number of packets received for a particular bgp routing policy on an interface.
C64 eriRouterBpaInOctetCount	1.3.6.1.4.1.193.218.2.20.1.1.1.3	Counter64	read-only	The total number of octets received for a particular bgp routing policy on an interface.
STR eriRouterBpaCircuitDescr	1.3.6.1.4.1.193.218.2.20.1.1.1.4	SnmpAdminString	read-only	A descriptive version of the interface that is consistent with information displayed in the CLI. This string is formatted as slot/port:channel:subchannel authority/level/index, with the exception that channel and subchannel are only included when appropriate. For example, 4/1 1/2/7, 4/1:1 1/2/7 or 4/1:1:1 1/2/7. If a circuit description is not available then this object contains a zero-length string
STR eriRouterBpaInterfaceName	1.3.6.1.4.1.193.218.2.20.1.1.1.5	SnmpAdminString	read-only	The name of the ip interface bound to a circuit. If ip interface name is not available then this object contains a zero length string
STR eriRouterBpaContextName	1.3.6.1.4.1.193.218.2.20.1.1.1.6	SnmpAdminString	read-only	The name of context in which this IP interface is defined. If context information is not available then this object contains a zero lenght string
