We use it for our system at work. It works fine on my M1 MBA under Rosetta 2.
Edited to add: Running version 4.9.04043
Thanks, had a hard time tracking down this particular version since Cisco themselves don’t seem to feel like making it available to Joe Public. My Uni’s Wiki unsurprisingly just linked to an outdated version (4.9.02028) but eventually did find it.
Appears to work nicely!
