Local configuration through console port.
Local or remote configuration through Telnet or Secure Shell (SSH).
A user interface view for specific configuration management.
Hierarchical command protection for users of different levels, that is, running the
commands of the corresponding level.
None authentication, password authentication and Authentication, Authorization and
Accounting (AAA) to prevent the unauthorized user from accessing the switch.
Entering "?" for online help at any time.
Network testing commands such as tracert and ping for rapidly diagnosing a network.
Abundant debugging information to help in diagnosing the network.
The telnet command for directly logging in to and manage other switch.
FTP service for file uploading and downloading.
Running a history command, like DosKey.
A command line interpreter provides intelligent command resolution methods such as key
word fuzzy match and context conjunction. These methods make it easy for users to enter
their commands.
NOTE
l The system supports the command with up to 512 characters. The command can be incomplete.
l The system saves the incomplete command to the configuration files in the complete form; therefore,
the command may have more than 512 characters. When the system is restarted, however, the
incomplete command cannot be restored. Therefore, pay attention to the length of the incomplete
command.
Level 0-Visit level: Commands of this level include commands of network diagnosis tool
(such as ping and tracert) and commands that start from the local device and visit external
device (such as Telnet client side).
