The port used to connect to the source. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_PORT , CHANGE MASTER TO  option: MASTER_PORT ) 

• USER 

The user name of the replication user account used to connect to the source. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_USER , CHANGE MASTER TO  option: MASTER_USER ) 

• NETWORK_INTERFACE 

The network interface that the replica is bound to, if any. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_BIND , CHANGE MASTER TO  option: MASTER_BIND ) 

• AUTO_POSITION

• SSL_ALLOWED , SSL_CA_FILE , SSL_CA_PATH , SSL_CERTIFICATE , SSL_CIPHER , SSL_KEY , SSL_VERIFY_SERVER_CERTIFICATE , SSL_CRL_FILE , SSL_CRL_PATH 

These columns show the SSL parameters used by the replica to connect to the source, if any. 

SSL_ALLOWED  has these values: 

• Yes  if an SSL connection to the source is permitted 

• No  if an SSL connection to the source is not permitted 

• Ignored  if an SSL connection is permitted but the replica does not have SSL support enabled

• CONNECTION_RETRY_COUNT 

The number of times the replica can attempt to reconnect to the source in the event of a lost connection. ( CHANGE REPLICATION SOURCE TO  option: SOURCE_RETRY_COUNT , CHANGE MASTER TO  option: MASTER_RETRY_COUNT ) 

• HEARTBEAT_INTERVAL
