                                    [--tags]. The 1th example of the child command would be to use it to 'update external seed nodes of a given cluster', the syntax is: az managed-cassandra cluster update --resource-group MyResourceGroup --cluster-name MyCluster --external-seed-nodes 127.0.0.1 127.0.0.2. The 2th example of the child command would be to use it to 'update external gossip certificates of a given cluster  certs can be passed in as strings or the file locations', the syntax is: az managed-cassandra cluster update --resource-group MyResourceGroup --cluster-name MyCluster --external-gossip-certificates C:/MyFolder/test.pem BeginCert-MLXCF-EndCert. The parameter '--cluster-name -c' is required. It is used to cluster name.. The parameter '--resource-group -g' is required.

The parameter '--client-certificates' is optional. if specified, enables client certificate authentication to the cassandra api.. The parameter '--cluster-type' is optional. type of the cluster, can be production or nonproduction. if set to production, operations on cluster might have restrictions.. The parameter '--extensions' is optional. a set of extensions that will be effective on the cluster. it will replace the entire set of extensions with new set. use "" to remove all. now available: cassandra-lucene-index.. The parameter '--external-gossip-certificates -e' is optional. a list of certificates that the managed cassandra data center's should accept.. The parameter '--external-seed-nodes' is optional. a list of ip addresses of the seed nodes of on-premise data centers.. The parameter '--hours-between-backups' is optional. the number of hours between backup attempts.. The parameter '--identity-type' is optional. type of identity used for customer managed disk key.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--repair-enabled' is optional. enables automatic repair.. The parameter '--tags' is optional. space-separated tags: key[=value] [key[=value] ...]. use "" to clear existing tags..
