Hi,
Thank you for participating in the Small Business support community. My name is Nico Muselle from Cisco Sofia SBSC.
With pleasure I can announce that the ping and traceroute function will be available in the next firmware release of the Sx300 series switches. Changing the system mode however is not (as far as I know). The firmware to be release will contain major updates and addition of functions like TextView (command line interface), CDP, smartports, QinQ etc ...
A little patience before this maintenance release is available, it will be certainly worth waiting for !
Best regards,
Nico Muselle
