I'd like to vet some initial feedback we've received on the use cases around creating IP SLA operations. The approach we've taken is to give you the ability to create IP SLA operations from a single IP address on a node. Here is the question: is it sufficient to be able to create operations for a single IP address on a node, or do you have use cases where you need to create unique operations for different IP addresses or interfaces on a particular node? If the latter, what problem are you trying to solve by creating the operation at the interface level? To ask the question in a different way, what are you missing by creating the operation at the node level? What are some use cases where an IP SLA operation limited to a single IP address on a node is insufficient?
