SSH not working after MDS 9148 upgraded from 5.0.1a. to 6.2.9b.

When use ssh hostname, one error happened. Before it was upgraded, there was no such kind of problem. Do you know why?

no matching cipher found: client aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc,rijndael-cbc@lysator.liu.se server aes128-ctr,aes192-ctr,aes256-ctr

Hello.  This issue you are experiencing is due to some older ciphers missing on the switch.  There is an enhancement bug for this, https://tools.cisco.com/bugsearch/bug/CSCuo68529

You can have your server group look at adding aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc to the list of usable ciphers for the server.

Thanks
