Example

To configure the specific KEX algorithm, execute the following command.

Copy 
OcNOS(config)#ssh server algorithm kex curve25519-sha256 
OcNOS(config)#ssh server algorithm kex curve25519-sha256 vrf management

To configure the multiple KEX algorithms, execute the following command.

Copy 
OcNOS#conf t Enter configuration commands, one per line. End with CNTL/Z.
OcNOS(config)#ssh server algorithm kex diffie-hellman-group-exchange-sha256 diffie-hellman-group14-sha256 ecdh-sha2-nistp256 
OcNOS(config)#ssh server algorithm kex diffie-hellman-group-exchange-sha256 diffie-hellman-group14-sha256 ecdh-sha2-nistp256 vrf management 
OcNOS(config)#commit OcNOS(config)#end

To unconfigure the multiple KEX algorithms, execute the following command.

Copy 
OcNOS(config)#no ssh server algorithm kex diffie-hellman-group-exchange-sha256 diffie-hellman-group14-sha256 
OcNOS(config)#no ssh server algorithm kex diffie-hellman-group-exchange-sha256 diffie-hellman-group14-sha256 vrf management
