Description (partial)

Symptom:
The Cisco Nexus 1000 (N1K) Series Switch supports Open Secure Socket Layer (OpenSSL) 
Rivest Cipher 4 (RC4) ciphers which are considered less secure than other more modern 
encryption algorithms. The N1K needs to remove support for RC4 ciphers or make that support
configurable by the user.

Conditions:
The device running with default configuration running an affected version of software.
This was tested via the command ''openssl s_client -connect xxx.xxx.xxx.xxx:443 -cipher RC4''.
