the parameters in the commands are supported by all switch models
by default, unless otherwise specified. For details, see specific
commands.

display compatible-information

Function

The display compatible-information command displays compatible information of a device.

Format

display compatible-information

Default Level

1: Monitoring level

Usage Guidelines

Generally, device versions have matching NMS software. The NMS software needs to apply to all the devices supported by matching versions. Otherwise, the NMS cannot manage devices. If the NMS version is an earlier version but the current device is running a later version that does not match the current NMS version, the NMS cannot manage the current device.

To decouple the NMS version and device version, a compatible device model developed based on an earlier version is defined for each device model. If the NMS cannot manage a device because of version mismatch, obtain information about the device compatible with the current device. The NMS can then use the obtained information to manage the current device.

For example:

S5700LI_R7 is a device model newly available in V200R007. The NMS software version that matches the device software version is V200R007.

S5700LI_R5 is a device model newly available in V200R005. The NMS software version that matches the device software version is V200R005.

When you use the NMS of V200R005 to manage S5700LI_R7, the device cannot be managed because of version mismatch. The NMS then obtains compatibility information about S5700LI_R7 and learns that it is compatible with S5700LI_R5. Subsequently, the NMS uses information about S5700LI_R5 to manage the current device.

If the device does not have a compatible version, the system will display a message, indicating that no compatible information exists after the display compatible-information command is executed.

Compatible information of stacked devices can also be displayed.

Example

# Display compatible information of a device.

Table 3-1 Description of the display compatible-information command output

Item	Description
Compatible SysOids	System OID of an old device version.
Compatible Version	Old device version compatible with the current device version.
ProductName	Product name of a new device.

display cpu-usage

Function

The display cpu-usage command displays CPU usage
statistics.

Format

display cpu-usage [ slave | slot slot-id ] [ vcpu vcpu ]

The slave parameter is not supported if the switch does not support the stacking
function or does not have the stacking function enabled.

Only the S5720HI supports the vcpu vcpu parameter.

Parameters

Parameter	Description	Value
slave	Displays the CPU usage of slave devices in a stack. This parameter is valid only in a stack system.	—
slot slot-id	Specifies the slot ID if stacking is not configured. Specifies the stack ID if stacking is configured.	The value is 0 if stacking is not configured. The value range depends on the stack configuration if stacking is configured.
vcpu vcpu	Displays the usage of a specified virtual CPU.	Specify the vcpu parameter based on the hardware configuration.

Default Level

1: Monitoring level

Usage Guidelines

CPU usage is an important indicator to evaluate device
performance. A high CPU usage will cause service faults, for example, BGP route flapping, frequent VRRP active/standby switchover,
and even failed device login. You can use the display cpu-usage command to view CPU usage to check whether devices are working properly.

When the CPU usage is high, rectify the fault according to «Troubleshooting:
High CPU» in Huawei S Series Campus Switches Troubleshooting
Guide.

Example

# Display the CPU usage on the device.

display cpu-usage configuration

Function

The display cpu-usage configuration command displays CPU usage configuration.

Format

display cpu-usage configuration [ slave | slot slot-id ]

The slave parameter is not supported if the switch does not support the stacking
function or does not have the stacking function enabled.

Parameters

Parameter	Description	Value
slave	Displays CPU usage configuration of standby switches in a stack. This parameter is valid only when multiple switches form stack.	—
slot slot-id	Displays device CPU usage configuration. slot-id specifies the stack ID.	The value is 0 if stacking is not configured. The value ranges from 0 to 8 if stacking is configured.

Default Level

1: Monitoring level

Usage Guidelines

This command displays the alarm threshold and recovery threshold.

When CPU usage reaches the alarm threshold, the system generates a CPU usage alarm.
When CPU usage falls within the recovery threshold, the system generates a clear alarm.

Example

# Display CPU usage configuration .

<HUAWEI> display cpu-usage configuration
The CPU usage monitor is turned on. 
The current monitor cycle is 60 seconds.
The current monitor warning threshold is 95%.
The current monitor restore threshold is 80%.

Table 3-3 Description of the display cpu-usage configuration command output

Item	Description
The CPU usage monitor	Whether the CPU usage monitoring function is enabled or disabled. To enable the CPU usage monitoring function, run the cpu-usage monitor command.
The current monitor cycle	CPU usage monitoring period, which cannot be configured.
The current monitor warning threshold	Alarm threshold. To set the CPU usage alarm threshold, run the cpu-usage threshold threshold-value [ restore restore-threshold-value ] [ slot slot-id ] command.
The current monitor restore threshold	Alarm recovery threshold. To set the CPU usage alarm recovery threshold, run the cpu-usage threshold threshold-value [ restore restore-threshold-value ] [ slot slot-id ] command.

display cpu-usage history

Function

The display cpu-usage history command
displays CPU usage statistics within a period.

Format

display cpu-usage history [ 1hour | 24hour | 72hour ] [ slave | slot slot-id ] [ vcpu vcpu ]

The slave parameter is not supported if the switch does not support the stacking
function or does not have the stacking function enabled.

Only the S5720HI supports the vcpu vcpu parameter.

Parameters

Parameter	Description	Value
1hour	Displays CPU usage statistics within the last one hour.	—
24hour	Displays CPU usage statistics within the last 24 hours.	—
72hour	Displays CPU usage statistics within the last 72 hours.	—
slave	Displays the CPU usage statistics of slave devices in a stack. This parameter is valid only in a stack system.	—
slot slot-id	Displays the CPU usage statistics of a specified slot ID.	The value varies with the device configuration.
vcpu vcpu	Displays the CPU usage statistics of a specified virtual CPU.	Specify the vcpu parameter based on the hardware configuration.

Default Level

1: Monitoring level

Usage Guidelines

Usage Scenario

The system collects CPU usage
statistics at a specified interval (usually 60s) and saves them in
the historical record table. To check CPU usage statistics within
a period, run the display cpu-usage history command,
and the command output helps you determine whether the CPU is working
properly.

In the display cpu-usage history command output, the x-coordinate indicates the specified period,
and the y-coordinate indicates the CPU usage.

Precautions

If CPU usage is constantly higher than the upper alarm threshold
(95% by default) before the feature is deployed on a large scale,
check the device to troubleshoot the fault.

Default Level

1: Monitoring level

Usage Guidelines

Usage Scenario

When a fault occurs in the
system, you can use the display diagnostic-information command to collect diagnostic information for fault location.

The display diagnostic-information command
output includes the output for multiple display commands, such
as display clock, display version, and display current-configuration. Running the display diagnostic-information command is like running
these display commands in batches.

Precautions

If the file-name parameter is not specified,
diagnostic information is only displayed on the screen. If the file-name parameter is specified, diagnostic information
is only stored to a specified file but not displayed on the screen, and the command level is management level (3).
If this command displays a long output, press Ctrl+C to abort this command.
This command displays diagnostic information, which helps locate
faults but may affect system performance. For example, CPU usage may
become high. Therefore, do not use this command when the system is
running properly.
Running the display diagnostic-information command simultaneously
on multiple terminals connected to the device is prohibited. This
is because CPU usage of the device may obviously increase and the
device performance may be degraded.
When you run this command, the device obtains or uses some
personal data of users, such as the STA MAC address. Delete the personal
data immediately after the command is executed to ensure user data
security.

In the preceding command output, the physical status of GE0/0/12 is Administratively DOWN, indicating that the shutdown command has been run on the interface. To enable the interface to go up, run the undo shutdown command in the interface view.

For a Layer 2 physical interface (an Ethernet interface works at Layer 2 mode by default): If its physical status indicated by the current state field displays up, its protocol status indicated by the Line protocol current state field displays up. For example, if a Layer 2 physical interface is connected correctly and its attribute configuration is correct, its physical status and protocol status are both up.
For a Layer 3 physical interface (The undo portswitch command has been run on the interface to change the working mode of the interface from Layer 2 mode to Layer 3 mode): Its protocol status indicated by the Line protocol current state field displays up only when its physical status indicated by the current state field displays up and its protocol negotiation succeeds. For example, if a Layer 3 physical interface is connected correctly, its attribute configuration is correct, and it is not configured with an IP address, its physical status and protocol status are up and down respectively.

The following table lists more commands for checking interface configurations or statistics.

Command	Description
display interface counters	Display statistics about packets sent or received on physical interfaces.
display interface ethernet brief	Display brief information about Ethernet interfaces, including the physical status, auto-negotiation mode, duplex mode, rate, and average bandwidth usages in the inbound and outbound directions in the recent period.
display counters error	Display error packet statistics on interfaces.
display error-down recovery	Display information about the interfaces in error-down state, including the interface name, cause of the error-down event, delay after which an interface changes to up, and remaining time for the up event.

Checking Interface Logs to Identify the Interface Status

You can run the display logbuffer command in any view to check interface logs. For example, if the following log information of the IFNET module is displayed, interfaces GigabitEthernet1/0/1 and GigabitEthernet3/0/0 are down.

Apr 15 2014 03:46:10-05:13 dgg62aslhw3i %%01IFNET/4/IF_STATE(l)[47]:Interface GigabitEthernet1/0/1 has turned into DOWN state.
Apr 15 2014 03:45:31-05:13 dgg62aslhw3i %%01IFNET/4/IF_STATE(l)[49]:Interface GigabitEthernet3/0/0 has turned into DOWN state.

Несколько часто используемых команд:

system-view — привелегированый режим
save – запись текущих настроек в энергонезависимую память устройства;
undo — отмена команды
display this — показ текущей конфигурации
display current-configuration – вывод текущего файла конфигурации
quit — выход

SNMP
Настроим SNMP:

snmp-agent
snmp-agent sys-info version v2c
snmp community read КОМЬЮНИТИ

Чтобы принимались простые community введем команду:

snmp-agent community complexity-check disable

Http

http secure-server enable
http server enable
display http server

Если возникнет ошибка «Error: Starting the HTTP server failed.«,
то значет не загружен web пакет который является web-интерфейсом (http сервером).

Посмотрим какие есть файлы в памяти коммутатора следующей командой
(нам нужен файл заканчивающийся расширением .web.zip):

dir

Если файла нету, то его необходимо закачать в память коммутатора.
Когда он будет находится в памяти коммутатора, запустим его командой:

http server load flash:/имя_файла.web.zip

Теперь включим его командами:

http secure-server enable
http server enable
http secure-server ssl-policy 1

Для подключения к коммутатору необходимо в программе SecureCRT выбрать File — Connect in Tab/Tile…

File — Connect in Tab/Tile…

Далее в появившемся окне выбираем любой агрегатор и нажимаем Connect (либо дабл-клик по агрегатору).

Connect

В итоге мы будем подключены по telnet к агрегатору.

Подключение к агрегатору

Далее необходимо подключиться непосредственно к коммутатору. Для этого прописываем команду telnet %ip-адрес_коммутатора%. После запроса системы вводим логин и пароль.

telnet 10.136.242.22

Для просмотра суммарной информации по статусам и конфигурациям интерфейсов коммутатора в виде сводной таблицы используется команда display interface brief

display interface brief

Для просмота логов коммутатора используется команда display logbuffer

display logbuffer

Если нам необходимо посмотреть, к примеру, информацию по какому-то конкректному интерфейсу, то используем дополнительные параметры команды. В нашем случае команда будет выглядеть так: display logbuffer | include %Имя_интерфейса%

display logbuffer | include Ethernet0/0/19

Команда для просмотра таблички с МАС-адресами клиентов и IP-адресами, которые им присвоены: display dhcp snooping user-bind all

display dhcp snooping user-bind all

Если нам необходимо посмотреть табличку по конкретному интерфейсу, используется команда display dhcp snooping user-bind interface %Имя_интерфейса%

display dhcp snooping user-bind interface Ethernet 0/0/18

Можно посмотреть «соседа», то есть к какому коммутатору подключен данный коммутатор. Для этого используется команда display lldp neighbor interface %Имя_интерфейса%

display lldp neighbor interface GigabitEthernet 0/0/1

На картинке выше видим, что порт GE0/0/1 коммутатора Nevskogo22_1-2 (к которому мы подключены) соединен с портом GE0/0/2 коммутатора Lizyukova37-1.

Для отслеживания информации на оборудовании в режиме реального времени используется команда terminal monitor

terminal monitor

Переход в режим конфигурирования осуществляется с помощью команды system-view. Стоит обратить внимание, что sysname оборудования при этом будет указываться не в треугольных скобках <>, а в квадратных – [].

system-view

В этом режиме мы можем, к примеру, отключить административно какой-либо из интерфейсов. Для этого заходим на сам интерфейс: interface %Имя_интерфейса%

interface Ethernet0/0/24

И прописываем команду shutdown

shutdown

Чтобы проверить отключен ли интерфейс возращаемся из режима конфигурирования с помощью команды quit в обычный пользовательский режим

quit

И пропишем команду display interface brief

display interface brief

Как видим порт отключен административно. Теперь включим его. Для этого возращаемся в режим конфигурирования, заходим на интерфейс и отменяем отключение с помощью команды undo %имя_команды%

undo shutdown

Проверяем, теперь порт административно включен:

Порт включен административно

На этом же коммутаторе видим, что на 15 порту есть ошибки:

Ошибки на порту

Сбросим ошибки с помощью команды reset counters interface %Имя_интерфейса%

reset counters interface Ethernet 0/0/15

Видим, что после ввода команды ошибки сброшены:

Ошибок на порту нет
