Cisco IP SLA can be done between two Cisco devices or between a Cisco device and another vendor’s device. There are different network components that have different roles in the network. These are:
IP SLA Source: is a Cisco device that generates the simulated traffic to a Cisco device IP SLA Responder or to any ip device.
IP SLA Responder: is a component in remote Cisco device that receives and sends the traffic with the help of IP SLA Control Protocol. Only Cisco devices can be an IPSLA Responder.
IP SLA Control Protocol is the protocol used by IPSLA Responder to determine which port to listen and to respond.
show ip cache flow: Displays a summary of the NetFlow switching statistics.
show ip flow interface: Displays NetFlow switching configuration for interfaces.
show ip flow export: Displays the current NetFlow configuration
show flow timeout: Displays information about NetFlow timeouts
NetFlow collection is enabled on an interface-by -interface basis, and it is unidirectional. This means you can enable it to capture traffic inbound on an interface with the ip flow ingress command or outbound on an interface with the ip flow egress command.
Flexible NetFlow is basically an extension of NetFlow v9. Flexible NetFlow provides enhanced optimization, reduces costs and improves capacity planning and security detection beyond traditional flow technologies. Flexible NetFlow, similar to traditional Netflow, requires CEF to be enabled for IPv4 and IPv6.
