You have created the SSH encryption keys, but you cannot enable SSH version 2. What is the problem?

When you're configuring a switch or router for SSH version 2, the key strength must be at least 768 bits for the modulus. The default is 512 bits, and it is standard practice to double the number to 1024 bits. The time and date do not need to be corrected to enable SSH version 2. The DNS server does not need to be configured for SSH version 2. Host records for the switch or router do not have to be configured for SSH version 2.
