CUCM 12.5 Remove Weak Key Exchange Algorithms for SSH

[vinothbalaji.dd]

Client found that CUCM Supports Weak Key Exchange Algorithms

In CUCM, If we disable diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1;

              But keeping only diffie-hellman-group-exchange-sha256, ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521;

              Will there be any Service impact or will this break anything?

CUCM version: 12.5.1.11900-146
