CLI Command Modes
Since the set of CLI commands is very large, the CLI is structured as a
command-tree hierarchy, where related command sets are assigned to
command modes for easier access. At each level, only the commands related
to that level are available to the user and only those commands are shown in
the context sensitive help for that level.
In this guide, commands are organized into multiple categories:
• Layer 2 Switching commands
• Security commands
• Audio Visual Bridging commands
• Data Center Technology commands
• Layer 3 Routing commands
• Switch Management commands
Layer 2 Switching describes the commands used for filtering and forwarding
of packets within a VLAN based upon learned MAC addresses.
Security describes the commands used to configure switch administrator and
end user network access.
Audio Visual Bridging describes the commands utilized to configure IEEE
802.1BA systems.
Data Center Technology describes the commands used to configure ANSI
T11 FC-BB-5 and OpenFlow capabilities.
Layer 3 Routing describes the commands used to forward packets within and
across VLANs based upon the IP addresses as well as management of the
routing protocols necessary to enable the distribution of routes.
Switch Management describes commands used to manage the switch.
Commands that cause specific actions to be taken immediately by the system
and do not directly affect the system configurations are defined at the top of
the command tree. For example, commands for rebooting the system or for
downloading or backing up the system configuration files are placed at the
top of the hierarchy tree.
Commands that result in configuration changes to the switch are grouped in
a Global Configuration sub tree.
