How do you activate SSH on C5210 wireless controllers? Netsight keeps giving us errors that it can not communicate via SSH. I don't remember having to set up SSH on my C4110 controllers.
SSH is highly likely to be enabled and available and working as it is enabled by default. The errors you are seeing are more likely to indicate that your C5210 isn't synchronized correctly with Netsight. You may have to review both what CLI credentials are being used to communicate with it in Netsight and whether the Langley Shared Secret is correctly configured.
