Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
Indicates a potentially hazardous situation which, if not avoided, could result in equipment damage, data loss, performance deterioration, or unanticipated results. NOTICE is used to address practices not related to personal injury. Calls attention to important information, best practices and tips.
NOTE is used to address information not related to personal injury, equipment damage, and environment deterioration. Security Conventions. Password setting. To ensure device security, use ciphertext when configuring a password and change the password periodically. The switch considers all passwords starting and ending with%^%#,%#%#,%@%@ or @%@% as ciphertext and attempts to decrypt them. If you configure a plaintext password that starts and ends with%^%#,%#%#,%@%@ or @%@%, the switch decrypts it and records it into the configuration file (plaintext passwords are not recorded for the sake of security). Therefore, do not set a password starting and ending with%^%#,%#%#,%@%@ or @%@%.
When you configure passwords in ciphertext, different features must use different ciphertext passwords. For example, the ciphertext password set for the AAA feature cannot be used for other features.
Encryption algorithms The switch currently supports the 3DES, AES, RSA, SHA1, SHA2, and MD5. 3DES, RSA, and AES are reversible, whereas SHA1, SHA2, and MD5 are irreversible. Using the encryption algorithms DES, 3DES, RSA (RSA-1024 or lower), MD5 (in digital signature scenarios and password encryption), or SHA1 (in digital signature scenarios) is a security risk. If protocols allow, use more secure encryption algorithms, such as AES, RSA (RSA-2048 or higher), SHA2, or HMAC-SHA2.
An irreversible encryption algorithm must be used for the administrator password. SHA2 is recommended for this purpose.

Non-Huawei-certified optical modules are not recommended because they may cause the following problems:. Such optical modules cannot be installed in optical interfaces because their structure is nonstandard. The structure and size of some non-Huawei-certified optical modules do not comply with the MSA agreement. After such an optical module is installed in an optical interface, the neighbor interface cannot have an optical module installed because the non-Huawei-certified optical module has a nonstandard size.
The device data bus is abnormal because of the data bus defects of the non-Huawei-certified optical module. Some non-Huawei-certified optical modules have data bus design defects. When such an optical module is used on a device, the data bus of the device will become abnormal.
As a result, data on the data bus cannot be read. The edge connector of the optical module has a nonstandard size, damaging the electronic components of the interface. Edge connectors of some non-Huawei-certified optical modules have a nonstandard size, causing an interface to be short-circuited and damaging the electronic components of the interface.
Optical module temperature monitoring is not standardized, causing alarms to be incorrectly generated. The temperature monitoring systems of some non-Huawei-certified optical modules do not comply with industry specifications, and so a high temperature is obtained. As a result, the system incorrectly reports a temperature alarm. The optical module register is set incorrectly.
Consequently, parameters and diagnostic information cannot be read or read incorrectly. The A0 registers of some non-Huawei-certified optical modules are set incorrectly. As a result, parameters and diagnostic information cannot be read or read incorrectly by the data bus. The optical module design does not comply with the EMC, its anti-electromagnetic interference capability is low, and the optical module brings electromagnetic interference to surrounding devices.
The working temperature range of the optical module does not meet requirements, causing the optical power to be reduced at a high temperature. Subsequently, services are interrupted.

Troubleshooting Procedure. Run the display interface command in the user view to check whether the receive optical power Rx Power of the optical module on the local interface is within the allowed range. If so, collect alarms, logs, and configurations, and then contact Huawei technical support personnel through Ask for Help.
Check whether an alarm is generated for high transmit optical power on the peer optical module. If so, first rectify the fault on the peer optical module. Check whether the local optical module matches the peer optical module.
If not, replace the local optical module to match the peer optical module. Add an optical attenuator to the local optical module by -5 dBm (recommended). If the fault persists after the preceding operations are performed, collect alarms, logs, and configurations, and contact Huawei technical support personnel through Ask for Help.
The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information. You are advised to use Huawei-certified optical modules. You can run the display transceiver interface interface-type interface-number verbose command to view power information of a specified optical module. The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information.
You are advised to use Huawei-certified optical modules. Optical signals sent from different types of sources can transmit over different distances due to negative effects of optical fibers, such as dispersion and attenuation. When connecting optical interfaces, select optical modules and fibers according to the longest signal transmission distance. You can run the display transceiver interface interface-type interface-number verbose command to view the transmission distance of a specified optical module. The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information. You are advised to use Huawei-certified optical modules.
You can run the display transceiver interface interface-type interface-number verbose command to view the temperature, voltage, and current of a specified optical module. You may fail to obtain optical module information in the following situations:. A non-Huawei-certified optical module is used. No optical module is installed. The system does not support the query of the temperature, voltage, current, receive power, and transmit power of the optical module. If the transmit or receive power displays NA, the interface does not have any transmit or receive signal and the power is 0. The optical module experiences a hardware fault.
You can replace the optical module for fault location. Optical fibers are classified into single-mode fibers and multi-mode fibers based on core diameters and features. Generally, multi-mode fibers have large core diameters and severe dispersion, so they transmit optical signals over short distances. Single-mode fibers have small dispersion and can transmit optical signals over long distances. Optical fibers and optical modules must work together.
When single-mode optical modules use multi-mode fibers, signal identification is unstable. When multi-mode optical modules use single-mode fibers, receive power loss is high.
The system may fail to obtain information about non-Huawei-certified optical modules or obtain incorrect information. You are advised to use Huawei-certified optical modules.

If the device configuration has been deleted using the reset saved-configuration command after startup, you cannot determine whether the device has started using the initial configuration. Display startup MainBoard: Startup system software: flash:/software.cc Next startup system software: flash:/software.cc Backup system software for next startup: flash:/software.cc Startup saved-configuration file: NULL Next startup saved-configuration file: NULL Startup paf file: default Next startup paf file: default Startup license file: default Next startup license file: default Startup patch package: NULL Next startup patch package: NULL. Users lower than level 3 (management level) cannot run the display current-configuration command to view the current device configuration.
By default, the users on the console port are at level 15. You can log in to a device through the console port and run the user privilege command in the user interface view to set other users (for example, Telnet users and SSH users) to level 3 or higher. For example, you can set the level of VTY0 users to level 3. System-view Huawei user-interface vty 0 Huawei-ui-vty0 user privilege level 3. You can run the screen-length screen-length temporary command in the user view or user interface view to set the number of lines displayed on a terminal screen.
By default, 24 lines are displayed on a terminal screen. If screen-length is 0, the split screen function is disabled. That is, the system does not pause when the information cannot be completely displayed on one screen. Screen-length 40 temporary // temporary is mandatory in the user view. System-view Huawei user-interface console 0 Huawei-ui-console0 screen-length 40. CPU usage is an important indicator to evaluate device performance. A high CPU usage will cause service faults, for example, Border Gateway Protocol (BGP) route flapping, frequent Virtual Router Redundancy Protocol (VRRP) switchovers, or even user login failures.
You can use the following commands to view CPU usage statistics and configurations in real time and verify that the device is running stably. You can view CPU usage configurations to learn about the CPU usage alarm threshold and CPU usage alarm recovery threshold. When the CPU usage reaches the alarm threshold, the system generates a CPU usage alarm. When the CPU usage falls below the recovery threshold, the system generates a clear alarm. Process Name Process Description cap32 Service forwarding task.
If this task has a high CPU usage, the CPU is receiving and processing a large number of protocol packets. When this occurs, the device may be undergoing an IP packet attack. Vrp Virtual routing task.
If this task has a high CPU usage, services on the CPU control plane increase instantly. Monitor Monitoring task. This task often has a low CPU usage. VALP Task of implementing the NAT ALG protocol stack. This task has a CPU usage when packets are sent to the control plane for processing after the NAT ALG function is enabled.
System CPU usage is within the normal range if the following conditions are met:. The CPU usage does not exceed 80% when the system runs for a long period.
The CPU usage does not exceed 95% in a short period and does not keep increasing. No high CPU usage alarm is generated. In the following scenarios, the system may generate an alarm when CPU usage becomes high instantly and then clear this alarm rapidly. This situation is a normal situation and does not affect the device operation. Cards just start. Information about all optical modules is queried at a time.
Traffic volume increases instantly. CPU usage of a CPU task process may become low or high, depending on the service volume and processing time. CPU usage is within a normal range as long as the system CPU usage does not exceed 80% and no high CPU usage alarm is generated. When a device has a high CPU usage, perform the following operations:. Check whether the CPU usage keeps increasing or increases instantly. If the CPU usage increases instantly, an operation may be performed, for example, the device just starts, information about all optical modules is queried at a time, and traffic volume increases instantly.
This situation does not affect the device operation. Check which task process causes a high CPU usage and analyze the task. Check log information and alarm information to determine whether a hardware fault alarm is generated. Check whether an interface frequently alternates between Up and Down states according to log information and alarm information. If so, check whether the optical module of the interface is faulty or a non-Huawei-certified optical module is used. Additionally, analyze the configuration and traffic volume of the interface. Check whether network management operations are frequently performed on the device.
Check whether STP flaps or routing protocols flap. Check whether the network structure changes and whether a loop occurs on the network. Check whether malicious attacks exist.
