[Puppet Users] where can I set the frequency that the clients update with the server

puppet agent --genconf | vim -

gives me
# How often puppet agent applies the client configuration; in seconds.
# Note that a runinterval of 0 means "run continuously" rather than
# "never run." If you want puppet agent to never run, you should start
# it with the `--no-client` option.
# The default value is '1800'.
# runinterval = 1800
