"This MIB module consists of two parts.
1) Auto-Ethernet-CFM Control:
|-- ipslaEthernetGrpCtrlTable
|-- ipslaEthernetGrpReactTable
2) ethernetJitter Stats:
|-- ipslaEtherJitterLatestStatsTable
|-- ipslaEtherJitterAggStatsTable
|-- ipslaEtherJitterAggBinTable
The first part defines a mechanism to manage IP SLA Auto-Ethernet-CFM operation.
IP SLA is a capability which utilizes active monitoring for network perfomance. It can be used for network troubleshooting, network assessment and health monitoring.
IEEE 802.1ag defines Connection Fault Management (CFM) for Ethernet layer. CFM can be used to detect, isolate and report the connectivity faults, and allows discovery and verification of the path through briges and LANs.
Auto-Ethernet-CFM operation integrates the capabilities of IP SLA and IEEE 802.1ag. It's capable of discovering all the existing MEPs in a specified VLAN or Ethernet Virtual Connection within a specified maintenance domain. After which, it creates, configures, and schedules an IP SLA operation for each MEP automatically.
IP SLA currently supports two types of operations for end-to-end Ethernet connectivity - 'ethernetPing' and 'ethernetJitter'.
'ethernetPing' can be used to monitor the connectivity and measure RTT by sending the regular 802.1ag loopback frame to a particular MEP.
'ethernetJitter' can be used to measure metrics such as RTT, Jitter, frame loss, one-way latency by sending multiple enhanced CFM frames at specified interval to a particular MEP.
Without Auto-Ethernet-CFM operation, the two types of operations can also be created, configured, and scheduled manually through CISCO-RTTMON-MIB by specifing the target MEP's identifier in addition to the VLAN or Ethernet Virtual Connection and Maintenance Domain.
With Auto-Ethernet-CFM operation, the two types of operations will be created automatically. The Auto-Ethernet-CFM will pass all the values specified in this module to the corresponding objects in CISCO-RTTMON-MIB for each MEP discovered.
ipslaEthernetGrpCtrlTable -> rttMonCtrlAdminTable
|-> rttMonEchoAdminTable
ipslaEthernetGrpReactTable -> rttMonReactTable
The second part defines a collection of statistics resulting from 'ethernetJitter' operation created either manually or automatically.
CFM - Connection Fault Management
DSAP (Domain Service Access Point): A member of a set of SAPs at which a Maintenance Domain is capable of offering connectivity to systems outside the Maintenance Domain.
IP SLA - Cisco IOS IP Service Level Agreements
IP SLA operation - Refers to the 'ethernetPing' or 'ethernetJitter' operation supported by IP SLA.
MEP - Maintenance association End Point: An actively managed CFM entity, associated with a specific DSAP of a service instance, which can generate and receive CFM PDUs and track any responses.
maintenance domain - The network or the part of the network for which faults in connectivity are to be managed.
The boundary of a Maintenance Domain is defined by a set of DSAPs, each of which can become a point of connectivity to a service instance.
Maintenance Domain Name - The identifier, unique over the domain for which CFM is to protect against accidental concatenation of service instances, of a particular Maintenance Domain.
RTT - Round Trip Time
SAP - Service Access Point at which a service is offered.
service instance - A service instance is a set of SAPs, selected from among the DSAPs defining a Maintenance Domain, such that a Data.Request primitive presented to one SAP can result in a Data.Indication primitive
occurring at one or more of the other SAPs in the set.
It corresponds to a VLAN or an Ethernet Virtual Connection.
TLV - Stands for Type, Length, Value, and denotes a method of encoding variable-length and/or optional information in a PDU. TLVs are not aligned to any particular word or octet boundary. TLVs follow each other with no padding between TLVs.
VLAN - Virtual Local Area Network: A subset of the active topology of a Bridged Local Area Network. Associated with each VLAN is a VLAN Identifier.
