Also, network vendors have been incorporating visibility (read: netflow, sflow etc) for a long time, so the comment above changing NW vendors because Cisco is embedding technology to HELP YOU is funny. Obviosuly just a marketing troll.

The data in question, be it personally identifiable information, or simply network data, is not Cisco's. And, Cisco has absolutely no right to it what-so-ever. And, as negligible as it may be, who is providing the tab for the bandwidth for the data being sent; the data that I do not agree to send? My network statistics are as confidential as the information that flows on my networks. If Cisco is gravitating toward strong armed ignorance in it's company policies, I am sure that we can expect the same ignorance in product design to follow. Up until now, my company (which will not be mentioned here,) has used Cisco devices. And, a whole lot of them. Thank you for the heads up. I can now begin looking for a viable replacement device manufacturer. Cisco, if we would have been given a choice, that would have been one thing. But unfortunately, you forgot who works for who. Thanks for the extra work, and hassle. Goodbye.

I don't think referencing SNMP Traps as a way to capture performance data is accurate. More accurately, the SNMP Service provides access to MIB data, if supported by a platform, can provide critical performance data for analysis.
Additionally, one should always understand the security implications of turning on a service like SNMP, particularly, if you're talking about either Version 1 or 2 of the protocol. SNMP version 3 has been slow to catch on except in network vendors' products.
