Code version 3.4.0.17. I have advanced configuration enabled in the GUI. Administration guide of the CBS 250 refers to RSPAN but I cannot find RSPAN features in the GUI or CLI, only SPAN. Of course, I am aware that not all documentation is accurate.
I want to mirror the traffic of a port to another switch, CBS 350, for monitoring. The CBS 350 does have RSPAN commands.
Is RPSAN a feature of the CBS 250?

I have my answer here
"From a functionality standpoint, key differentiators [CBS 250 and CBS 350] are PoE budget, Stacking and some advanced security features like BPDU guard, Dynamic ARP inspection, sFlow, RSPAN, etc."

Have a look at this document using the CLI to configure RSPAN.

Herein lies the problem. In the guide you mentioned above, which is titled "Cisco Business switches 250 sereies CLU guide". RSPAN is mentioned 65 times and how to configure is shown but these commands are not available in the CBS 250 I have.

Hi,
To my knowledge CBS250 series support SPAN only contrary to CBS350 which support both SPAN and RSPAN. You can check at the Cisco "Business 250 Smart Switches: Administration Guide" where under the chapter "Status and Statistics" only the "SPAN" is listed.
Best regards,

Is you knowlesdge based on actual experience of just reading the guides, which I have done?

"Of course, I am aware that not all documentation is accurate."
True, and fortunately, usually not too often.
A variation I've bumped into, general software documentation sometimes has exceptions noted in other documentation like release notes or hardware specific documentation.
You initial reply quotation appears to be from a Cisco employee, so it's possible the feature was planned for the CBS250, but at the last minute, not provided on it to enhance the value of the CBS350. Also possibly too much trouble (expense) to revise CBS250 documentation.
BTW, I wouldn't be surprised the feature is actually in the CBS250 code, and would work correctly, but invocation blocked.
