Commands
Commands can be sent to the Cisco Nexus 3550-F Fusion (formerly ExaLINK Fusion) using a command line interface, of which the available commands are listed below.
Note
The CLI has a modal structure. User permissions/roles are not tested on entry to various operating modes, however they are tested when a command is executed within a mode. For example, all users can enter config port however only users with appropriate roles can execute a command such as setting the speed for that port.
Note
Commands that are preceded by
config or debug do not need that prefix at the start when in the
corresponding mode.
