Description (partial)

This is an enhancement that is being filed to add support for stronger encryption methods within the SSH client on the Cisco Catalyst 9000 Series platform.

New command syntax will provide compatibility between the SSH client and SSH Servers that do not support diffie-hellman-group1-sha1 and diffie-hellman-group14-sha1 encryption methods.

SSH from a Catalyst 9300 to a SSH Server that does not support the current key exchange algorithms diffie-hellman-group-exchange-sha1 and diffie-hellman-group14-sha1 does not work.
