Show Flash command
You can use the show flash command to display FLASH capacity and current usage
information about FLASH allocation and files, if present, to provide information about dual
images and backup configurations. You can display the actual file sizes and space allocated
to them.
SSH Client
Present only on switches with SSH images, and available only through ACLI, SSH Client uses
SSH version 2. It is a secure shell protocol you can use to connect to an SSH Server device
in the network that accepts remote connections.
SSH RSA Authentication
SSH RSA Authentication provides increased security for Secure Shell (SSH) login. With this
feature, the switch supports RSA public-private key encryption that uses a digital certificate.
SSH RSA Authentication is supported when you select the RSA certificate option for a Secure
Shell connection from a client PC to the switch.
Stack Health Monitoring and Recovery
You can use Stack Health Monitoring and Recovery for more robust switch discovery and to
obtain additional reports about stack communication failure. You can also use the recovery
function to detect logical or software problems in a switch or stack.
