Cisco Bug: CSCvs29183 - WLC still shows weak SSH encryption algorithms with encryption high enabled

Known Affected Releases

8.10(105.0) 8.5(140.0) 8.5(151.0) 8.8(120.0)

Description (partial)

It is expected that the option "config network ssh cipher-option high" would remove the weak algorithms from WLC list of supported algorithms for SSH connections.
However, if we do a ssh scan using a tool like nmap, the WLC lists exactly the same algorithms before and after applying the command and rebooting the WLC.

Customers expect that the weak algorithms to be removed from the WLC supported algorithms list after enabling high ciphers for SSH connections.

The WLC CLI command "config network ssh cipher-option high" is configured.
