CISCO-FLOW-CLONE-MIB
This MIB module defines objects that manages flow cloning feature. A flow cloning can be described as a hardware or software entity, that is responsible to clone (or duplicate) flows to the specified destination port in the device. These cloned packets will be sent to an external device for a more fine-grained analysis of the flows. A typical application of this MIB module will facilitate cloning media flows. However, by no means does the definition of this MIB module prevents other applications from using it. CLONE PROFILE: ============== At the top level, this MIB module describes the notion of flow cloning. Further descriptive texts in this MIB will use clone profile to describe flow cloning. We can think of clone profile as a container for the traffic flows for which it will clone packets and send out on the specified egress interface. Because a device can support more than one clone profile, this MIB defines cfcCloneProfileTable. TRAFFIC FLOW: ============= At the next level, this MIB module describes the notion of a traffic flow associated with the clone profile. A traffic flow is a unidirectional stream of packets conforming to a classifier.For example, packets having a particular source IP address, destination IP address, protocol type, source port number, and destination port number. CLONE TARGET: ============= A clone target may represent an entity that the system provisions with a clone profile. Clone targets include, but are not necessarily limited to, the system, nodes (i.e., an instance of an operating system), interfaces, VRF instances, and bridge domains. IMPLEMENTATION GUIDANCE ======================= It might seem that the concepts presented by this MIB module lend themselves to a profile-based approach. However, this approach provides the most general abstraction and lends itself to implementations that can fall under two categories: global and per-interface. A global level clone profile will clone the specified flows that are monitored in the whole device. Per interface clone profile will clone the specified flows that are monitored on the specified interface. This MIB module can represent the global level clone profile using the following procedure: o Create a row in the cfcCloneProfileTable having the following attributes. Allocate a value for cfcCloneProfileId and a name for cfcCloneProfileName. For sake of discussion, let's say the value is <X> and the name is 'XYZ'. cfcCloneProfileId = <X> cfcCloneProfileName = <XYZ> . . cfcCloneTargetType = 'system' o Similarly per interface level clone profile implementation can be represented as follows. Create a row in the cfcCloneProfileTable having the following attributes. Allocate a value for cfcCloneProfileId and a name for cfcCloneProfileName. For sake of discussion, let's say the value is <Y> and the name is 'ABC'. cfcCloneProfileId = <Y> cfcCloneProfileName = <ABC> . . cfcCloneTargetType = 'interface' cfcCloneTargetIfIndex = <ifindex> While this example illustrates how an implementation may represent global and per-interface configuration data, it is understood that an implementation may have other requirements. In these cases, use this example as a guide in satisfying these requirements.
