Sometimes when you use an command line utility, such as dmctl, sm_tpmgr, or sm_snmpwalk, you want to specify a Broker other than the default Broker, which is identified in the BASEDIR/smarts/local/conf/ file of the installation directory from which the command line utility is invoked; for example, localhost:426. To do so, you include the -b <Broker> option in the command line invocation.

The <Broker> syntax is hostname or IP address, followed by a colon (:) delimiter, followed by a port number. The combination of an IP (v4 or v6) address and port number is also called a socket.

“Conventions for specifying an IPv6 address with port number” section in Chapter 8, IPv6 Address Conventions, in the IP Manager Reference Guide provides information on the syntax.
