The cbpAcctTable table, which contains five variables, is the only object in the BGP-POLICY-ACCOUNTING-MIB MIB. It contains all the BGP Policy Accounting packet and byte counters for each (sub)interface and for both the input and output directions:
cbpAcctTrafficIndex is an integer value greater than 0 that uniquely identifies the bucket (also called traffic-type in the MIB).
cbpAcctInPacketCount is the total number of packets received for a particular bucket on an interface.
cbpAcctInOctetCount is the total number of octets received for a particular bucket on an interface.
cbpAcctOutPacketCount is the total number of packets transmitted for a particular bucket on an interface.
cbpAcctOutOctetCount is the total number of octets transmitted for a particular bucket on an interface.
The table indexes are ifIndex, which provides the (sub)interface identifier, and cbpAcctTrafficIndex, which references the bucket identifier.
Note that all counters are type Counter64 (64-bit), so SNMPv2 or SNMPv3 is required to access these counters.
