View

User view

Parameters

zone-name: Name of the summer time, a string of 1 to 32 characters. It is case sensitive.

start-time: Start time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours.

start-date: Start date, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD.

end-time: End time, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours.

end-date: End date, in the format of MM/DD/YYYY (months/days/years) or YYYY/MM/DD.

add-time: Time added to the standard time of the device, in the format of HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted except for indicating 0 hours.

Description

Use the clock summer-time one-off command to adopt summer time from the start-time of the start-date to the end-time of the end-date. Summer time adds the add-time to the current time of the device.

Use the undo clock summer-time command to cancel the configuration of the summer time.

After the configuration takes effect, you can use the display clock command to view it. Besides, the time of the log or debug information is the local time of which the time zone and summer time have been adjusted.

Note that:

l           The time range from start-time in start-date to end-time in end-date must be longer than one day and shorter than one year. Otherwise, the argument is considered as invalid and the configuration fails.

l           If the current system time is in the time range specified with this command, the system time automatically adds “add-time” after the execution of this command.

Related commands: clock datetime, clock summer-time repeating, clock timezone, display clock.

Examples

# For daylight saving time in abc1 between 06:00:00 on 08/01/2006 and 06:00:00 on 09/01/2006, set the system clock ahead one hour.

1.1.5  command-privilege

Syntax

command-privilege level level view view command

undo command-privilege view view command

View

System view

Parameters

level level: Command level, in the range 0 to 3.

view view: Specifies a view.

command: Command to be set in the specified view.

Description

Use the command-privilege command to assign a level for the commands in the specified view.

Use the undo command-privilege view command to restore the default.

By default, each command in each view has its specified level. Therefore, you are not recommended to modify the default command levels for fear of inconvenience brought to your operation and maintenance.

Command privilege falls into four levels: visit, monitor, system, and manage, which are identified by 0 through 3.

The administrator can assign a privilege level for a user according to his need. When the user logs on a device, the commands available depend on the user’s privilege. For example, if a user’s privilege is 3 and the command privilege of VTY 0 user interface is 1, and the user logs on the system from VTY 0, he can use all the commands with privilege smaller than three (inclusive).

The following table describes the default level of the commands.

Table 1-1 Default level of the commands

Command level	Commands
Visit (0)	ping, tracert, telnet
Monitor (1)	refresh, reset, send
System (2)	Configuration commands
Manage (3)	FTP, Xmodem, TFTP, file system operation commands

text: Regular expression, a string of 1 to 256 characters, case sensitive.

Table 1-2 Special characters in regular expression

Character	Meaning	Note
^	Starting sign, the string following it appears only at the beginning of a line.	Regular expression “^user” matches a string begins with “user”, not “Auser”.
$	Ending sign, the string before it appears only at the end of a line.	Regular expression "user$” matches a string ends with “user”, not “userA”.
(	Left bracket, used as a stack symbol in a program	It is not recommended to use this character to establish a regular expression.
.	Full stop, a wildcard used in place of any character, including blank	None
*	Asterisk, used to match a subexpression zero or multiple times before it	zo* can map to “z” and “zoo”.
+	Addition, used to match a subexpression one or multiple times before it	zo+ can map to “zo” and “zoo”, but not “z”.
-	Hyphen. It connects two values (the smaller one before it and the bigger one after it) to indicate a range together with [ ].	For example, “1-9” means numbers from 1 to 9 (inclusive); “a-h” means from a to h (inclusive).
[ ]	Selects one character from the group.	For example, [1-36A] can match only one character among 1, 2, 3, 6, and A.
( )	A group of characters. It is usually used with “+” or “*”.	For example, (123A) means a string “123A”; “408(12)+” can match 40812 or 408121212. But it cannot match 408. That is, “12” can appear continuously and it must at least appear once.

User view

Parameters

level: User level, in the range 0 to 3.

Description

Use the super command to switch from the current user level to a specified user level.

There are four levels of commands:

l           Visit: involves commands for network diagnosis (such as ping and tracert), commands for accessing an external device (such as Telnet client, SSH client, RLOGIN). Saving the configuration file is not allowed at this level.

l           Monitor: includes the display and debugging commands for system maintenance, and service fault diagnosis. Saving the configuration file is not allowed at this level.

l           System: provides service configuration commands, including routing and commands at each level of the network for providing services.

l           Manage: influences the basic operation of the system and the system support modules for service support. Commands at this level involve file system, FTP, TFTP, Xmodem download and configuration file switch, power control, standby board control, user management, level setting, as well as parameter setting within a system (the last case involves those non-protocol or non RFC provisioned commands).

Login users are also classified into four levels that correspond to the four command levels. After users at different levels log in, they can only use commands at their own, or lower, levels.

Note that:

Users can switch to a lower user level unconditionally. To log in through AUX, or VTY user interface and switch to a higher user level, however, they need to enter the password (The password can be set with the super password command.). If the entered password is incorrect or no password is configured, the switch fails. Therefore, before switching to a higher user level, users should configure the password needed.

Related commands: super password.

Examples

# Set the user level to 2 (The current user level is 3.).

<Sysname> super 2

User privilege level is 2, and only those commands can be used

whose level is equal or less than this.

Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE

# Switch the user level back to 3 (Suppose password 123 has been set; otherwise, the user level cannot be switched to 3.).

<Sysname> super 3

 Password:

User privilege level is 3, and only those commands can be used

whose level is equal or less than this.

Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE

1.1.19  super password

Syntax

super password [ level user-level ] { simple | cipher } password

undo super password [ level user-level ]

View

System view

Parameters

level user-level: User level in the range 1 to 3, with the default as 3.

simple: Plain text password.

cipher: Cipher text password.

password: Password, a string of characters. It is case-sensitive.

l           For simple password, it is a string of 1 to 16 characters.

l           For cipher password, it is a string of 1 to 16 characters in plain text or 24 characters in cipher text. For example, the simple text “1234567” corresponds to the cipher text “(TT8F]Y\5SQ=^Q`MAF4<1!!”.

Description

Use the super password command to set the password needed to switch from a lower user level to a higher one.

Use the undo super password command to restore the default.

By default, no password is set to switch from a lower user level to a higher one.

Note that:

l           If simple is specified, the configuration file saves a simple password.

l           If cipher is specified, the configuration file saves a cipher password.

l           The user must always enter a simple password, no matter simple or cipher is specified.

l           Cipher passwords are recommended, as simple ones are easily getting cracked.

Examples

# Set the password to abc in simple form for switching user-level to 3.

<Sysname> system-view

[Sysname] super password level 3 simple abc

Display the password for switching user-level.

[Sysname] display current-configuration

Parameters

ip: Supports IPv4 protocol.

-a source-ip: Specifies the source IP address of an ICMP echo request. It must be a legal IP address configured on the device.

-c count: Specifies the number of times that an ICMP echo request is sent, in the range 1 to 4294967295. The default value is 5.

-f: Discards packets larger than the MTU of a given interface, that is, the ICMP echo request is not allowed to be fragmented.

-h ttl: Specifies the TTL value for an ICMP echo request, in the range 1 to 255. The default value is 255.

-i interface-type interface-number: Specifies the ICMP echo request sending interface by its type and number. With the interface specified, the TTL of packets are set to 1 automatically to test the directly-connected device (the IP address of the device is in the same network segment with that of the interface).

-m interval: Specifies the interval (in milliseconds) to send an ICMP echo response, in the range 1 to 65535. The default value is 200 ms.

l           If a response from the destination is received within the timeout time, the interval to send the next echo request equals the actual response period plus the value of interval.

l           If no response from the destination is received within the timeout time, the interval to send the next echo request equals the timeout value plus the value of interval.

-n: Specifies that the Domain Name System (DNS) is disabled. DNS is enabled by default, that is, the hostname is translated into an address.

-p pad: Specifies the padded bytes in an ICMP echo request, in hexadecimal format. For example, if pad is configured as ff, then the packets will be padded with ff. By default, the padded bytes start from 0x01 up to 0x09, where another round starts again if necessary.

-q: Presence of this parameter indicates that only statistics are displayed. By default, all information is displayed.

-r: Records routes. By default, routes are not recorded.

-s packet-size: Specifies length (in bytes) of an ICMP echo request, in the range 20 to 8100. The default value is 56.

-t timeout: Specifies the timeout value (in milliseconds) of an ICMP echo request, in the range 0 to 65535. It defaults to 2000.

-tos tos: Specifies type of service (ToS) of an echo request, in the range 0 to 255. The default value is 0.

-v: Displays non ICMP echo reply received. By default, the system does not display non ICMP echo reply.

remote-system: IP address or host name (a string of 1 to 20 characters) of the destination device.

Description

Use the ping command to verify whether the destination device in an IP network is reachable, and to display the related statistics.

Note that:

l           You must use the command in the form of ping ip ip instead of ping ip if the destination name is a key word, such as ip.

l           Only the directly connected segment address can be pinged if the outgoing interface is specified with the -i argument.

Examples

# Check whether the device with an IP address of 10.1.1.5 is reachable.

Description

Use the schedule reboot at command to enable the scheduled reboot function and specify a specific reboot time and date.

Use the undo schedule reboot command to disable the scheduled reboot function.

By default, the scheduled reboot function is disabled.

There are two cases if no specific reboot date is specified:

l           When the specified reboot time is later than the current time, the device will be rebooted at the reboot time of the current day.

l           When the specified reboot time is earlier than the current time, the device will be rebooted at the reboot time the next day.

l           If you are performing file operations when the device is to be rebooted, the system does not execute the command for the sake of security.

Note that:

l           The precision of the device timer is 1 minute. One minute before the reboot time, the device will prompt “REBOOT IN ONE MINUTE” and will be rebooted in one minute.

l           The difference between the reboot date and the current date cannot exceed 30 x 24 hours (namely, 30 days).

l           After you execute the above command, the device will prompt you to confirm the configuration. You must enter <Y> or <y> to make the configuration take effect. The original configuration will be overwritten at the same time.

l           If a date (month/day/year or year/month/day) later than the current date is specified for the schedule reboot at command, the device will be rebooted at the reboot time.
