Command Language
Terminology
The CLI command language creates, manages, displays and removes system
entities. These entities describe system and network connections and processes.
Most of the managed entities in the system are slotted in tables. Some common
examples are:
■ Network - defines local and remote networks, network connections, hosts
and routers
■ Port - A table of parameters that describes the characteristics of a bridge port.
These parameters are used when establishing a network connection over the
WAN
■ User - A table of parameters that describes connection parameters associated
with Telnet users that wish to attach and remotely manage the unit
■ Filter - can be applied to interfaces, connections, and theernet port to control
access through the system
■ Interface - describes physical devices; for example, ports
■ Route - describes a path through the network to another system or network
Table entries are created with an add command, and removed with a delete
command. The add command specifies the most important parameters of the
entry. Additional parameters are usually specified with the set command, which is
also used to change configured parameters.
The list command displays table entries. For example, list users displays all
defined administrative login profiles.
The show command displays detailed information about a specific table entry. For
example, show user root displays detailed information for the administrative
login profile root.
