When configuring command line interface, go to these sections for information you are interested in:
l Features and Functions of Command Line
1.1 Command Line Interface
H3C series switches provide a series of configuration commands and command line interfaces for configuring and managing the switch. The command line interface has the following characteristics:
l Local configuration via the Console port and AUX port.
l Local or remote configuration via Telnet.
l Remote configuration through dialing with modem via the AUX port.
l Hierarchy command protection to avoid the unauthorized users accessing switch.
l Enter a “?” to get immediate online help.
l Provide network testing commands, such as Tracert and Ping, to fast troubleshoot the network.
l Provide various detailed debugging information to help with network troubleshooting.
l Log in and manage other switch directly, using the Telnet command.
l Provide FTP service for the users to upload and download files.
l Provide the function similar to Doskey to execute a history command.
l The command line interpreter searches for target not fully matching the keywords. You can key in either the whole keyword or part of it, as long as it is unique and not ambiguous.
1.2 Command Line View
H3C series switches provide hierarchy protection for the command lines to avoid unauthorized user accessing illegally.
Commands are classified into four levels, namely visit level, monitor level, system level and manage level. They are introduced as follows:
l Visit level: Commands of this level involve command of network diagnosis tool (such as ping and tracert), command of switch between different language environments of user interface (language-mode) and the telnet command. The operation of saving configuration file is not allowed on this level of commands.
l Monitor level: Commands of this level, including the display command and the debugging command, are used for system maintenance, service fault diagnosis, etc. The operation of saving configuration file is not allowed on this level of commands.
l System level: Service configuration commands, including routing command and commands on each network layer, are used to provide direct network service to the user.
l Manage level: They are commands that influence basis operation of the system and system support module, which plays a support role on service. Commands of this level involve file system commands, FTP commands, TFTP commands, XModem downloading commands, user management commands, and level setting commands.
At the same time, login users are classified into four levels that correspond to the four command levels respectively. After users of different levels log in, they can only use commands at the levels that are equal to or lower than their own level.
In order to prevent unauthorized users from illegal intrusion, users will be authenticated when switching from a lower level to a higher level with super [ level ] command. User ID authentication is performed when users at lower level switch to users at higher level. If users pass the authentication, they will switch to a higher level; otherwise, they will remain at the original user level.
Different command views are implemented according to different requirements. They are related to one another. For example, after logging into the switch, you will enter user view, in which you can only use some basic functions such as displaying the running state and statistics information. In user view, key in system-view to enter system view, in which you can key in different configuration commands and enter the corresponding views.
The command line provides the following views:
l User view
l System view
l Port view
l VLAN view
l VLAN interface view
l Local-user view
l User interface view
l FTP Client command view
l SFTP Client view
l MST region view
l PIM view
l MSDP view
l IPv4 multicast sub-address family view
l RIP view
l OSPF view
l OSPF area view
l BGP view
l IS-IS view
l Route policy view
l Basic ACL view
l Advanced ACL view
l Layer-2 ACL view
l Conform-level view
l WRED index view
l RADIUS server group view
l ISP domain view
l MPLS view
l VPNv4 sub-address family view
l VPN-instance sub-address family view
l BGP-VPNv4 sub-address family view
l MPLS L2VPN view
l L2VPN address family view
l Route-Policy view
l vpn-instance view
l OSPF protocol view
l Remote-peer view
l VSI-LDP view
l VSI view
l HWTACACS view
l Port group view
l Lanswitch view
l HGMP view
l NQA test group view
The following table describes the function features of different views and the ways to enter or quit. Port numbers are only for examples.

1.3.3 History Command of Command Line
Command line interface provides the function similar to that of DosKey. The commands entered by users can be automatically saved by the command line interface and you can invoke and execute them at any time later. History command buffer defaults to 10. The operations are shown in the table below.
Table 1-3 Retrieve history command
|
Operation |
Key |
Result |
|
Display history command |
display history-command [ command-number ] [ | { begin | include | exclude } Match-string ] |
Display history command by user inputting |
|
Retrieve the previous history command |
Up cursor key <↑> or <Ctrl+P> |
Retrieve the previous history command, if there is any. |
|
Retrieve the next history command |
Down cursor key <↓> or <Ctrl+N> |
Retrieve the next history command, if there is any. |
& Note:
Cursor keys can be used to retrieve the history commands in Windows 3.X Terminal and Telnet. However, in Windows 9X HyperTerminal, the cursor keys ↑ and ↓ do not work, because Windows 9X HyperTerminal defines the two keys differently. In this case, use the combination keys <Ctrl+P> and <Ctrl+N> instead for the same purpose.
1.3.4 Common Command Line Error Messages
All the commands input by users can be correctly executed, if they have passed the grammar check. Otherwise, error messages will appear. The common error messages are listed in the following table.
Table 1-4 Common command line error messages
