See Solana Clusters for general information about the available clusters.
You can check what cluster the Solana command-line tool (CLI) is currently targeting by running the following command:

solana config set command to target a particular cluster. After setting a cluster target, any future subcommands will send/receive information from that cluster.
For example to target the Devnet cluster, run:
solana config set --url https://devnet.solana.com
Though not strictly necessary, the CLI will generally work best when its version matches the software version running on the cluster. To get the locally-installed CLI version, run:
To get the cluster version, run:
Ensure the local CLI version is greater than or equal to the cluster version.
