network-operator

Parameters

job job-id: Specifies a process by its ID. The value range for job-id is 1 to 2147483647. If you do not specify a process, this command displays the statistics for the entire system's CPU usage (the total CPU usage of all processes). To view the IDs and names of the running processes, use the display process command. For more information, see Network Management and Monitoring Command Reference.

Usage guidelines

After CPU usage tracking is enabled, the system regularly samples CPU usage and saves the samples to a buffer. This command displays the most recent 60 samples in a coordinate system as follows:

· The vertical axis represents the CPU usage. If a statistic is not a multiple of the usage step, it is rounded up or down to the closest multiple of the usage step. For example, if the CPU usage step is 5%, the statistic 53% is rounded up to 55%, and the statistic 52% is rounded down to 50%.

· The horizontal axis represents the time.

· Pound signs (#) indicate the CPU usage. The value on the vertical axis for the topmost pound sign at a specific time represents the CPU usage at that time.

Examples

# Display the historical CPU usage statistics.

Views

System view

Predefined user roles

network-admin

Parameters

EM0: Specifies the EM0 resource pool.

EM1: Specifies the EM1 resource pool.

null: Binds no ACL rules.

ipsg: Specifies the type of ACL rule for matching the IPSG service. The template for this type of ACL rule includes the following:

· IPv4 template:

¡ Source IPv4 address + source MAC address + source port number + VLAN ID

¡ Source IPv4 address + source MAC address + source aggregate interface number + VLAN ID

· IPv6 template:

¡ Source IPv6 address + source MAC address + source port number + VLAN ID

¡ Source IPv6 address + source MAC address + source aggregate interface number + VLAN ID

mqc-dstipv4: Specifies the type of ACL rule for matching MQC destination IPv4 address service. This type of ACL rule matches only destination IPv4 addresses.

inof: Specifies ACL rules for matching the INOF service. The template for this type of ACL rule includes the following:

· IPv4 template: Source IPv4 address + destination IPv4 address.

· IPv6 template: Source IPv6 address + destination IPv6 address.

· static-ac: Specifies ACL rules for matching the static AC service. The template for this type of ACL rule includes the following:

· Source port number + VLAN ID

· Source aggregate interface number + VLAN ID

dynamics-ac: Specifies ACL rules for matching the static AC service. The template for this type of ACL rule includes the following:

· Source port number + Source MAC address + VLAN ID

· Source aggregate interface number + Source MAC address + VLAN ID

mac-vlan: Specifies ACL rules for matching the MAC-based VLAN service. This type of ACL rules matches only source MAC addresses. The mask for these source MAC addresses must be all Fs.

ipfix: Specifies ACL rules for matching the IPFIX service. The template for this type of ACL rule includes the following:

· Protocol carries by IPv4 + source IPv4 address + destination IPv4 address + source port number + destination port number

· Protocol carries by IPv4 + source IPv4 address + destination IPv4 address + source port number + ICMP message code

slot slot-number: Specifies an IRF member device by its member ID.

Usage guidelines

This feature allows the device to deploy the specified types of ACL rules through the EM engine, increasing the number of ACL rules the device supports. The EM engine can deploy the ACL rules for matching the following types of services: IPSG, MQC destination IPv4 address, INOF, static AC, dynamic AC, MAC-based VLAN, and IPFIX.

When a type of ACL rule is bound to an EM resource pool, the device will use EM resources for packet matching. EM resources are a type of forwarding entry resource on the device, stored in the same hardware space as MAC addresses and routing tables. Using EM resources for packet matching can increase the device's packet matching specifications.

For example, the type of ACL rule for matching the IPFIX service includes protocol carried by IPv4 + source IPv4 address + destination IPv4 address + source port number + destination port number. If the device only configures a type of ACL rule that includes protocol carried by IPv4 + source IPv4 address + destination IPv4 address + source port number + destination port number, but does not bind that type of ACL rule to an EM resource pool, the device uses TCAM resources for packet matching. However, TCAM resources are limited. To resolve this issue, after configuring ACL rules that includes protocol carried by IPv4 + source IPv4 address + destination IPv4 address + source port number + destination port number, bind this type of ACL rule for the IPFIX service to an EM resource pool. Then, the device will use EM resources to perform packet matching for the IPFIX service.

To clear all ACL rules bound to an EM resource pool, execute the hardware-resource { EM0 | EM1 } null command.

The ACL rules for matching MQC destination IPv4 addresses through EM resources supports only the Layer 2 port inbound direction and are only suitable for scenarios that do not differentiate ACL rules or CB pair priorities.

The EM1 resource pool does not support binding any types of ACL rules.

In IRF mode, after EM0 resource pool binding, save the configuration to the subordinate device to prevent configuration upon a device restart.

Examples

# Bind the type of ACL rule for the IPSG service to the EM0 resource pool.

<Sysname> system-view

[Sysname] hardware-resource EM0 ipsg slot 1

# Clear all ACL rules bound to the EM0 resource pool.

Predefined user roles

network-admin

Parameters

ratio: Specifies free-memory thresholds in percentage. If you do not specify this keyword, the command sets free-memory thresholds in MB.

minor minor-value: Specifies the minor alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the minor-value argument. Setting this threshold to 0 disables the minor alarm feature.

severe severe-value: Specifies the severe alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the severe-value argument. Setting this threshold to 0 disables the severe alarm feature.

critical critical-value: Specifies the critical alarm threshold. To view the value range for this threshold, enter a question mark (?) in the place of the critical-value argument. Setting this threshold to 0 disables the critical alarm feature.

normal normal-value: Specifies the normal state threshold. To view the value range for this threshold, enter a question mark (?) in the place of the normal-value argument.

Usage guidelines

To ensure correct operation and improve memory efficiency, the system monitors the amount of free memory space in real time. If the amount of free memory space decreases to or below the minor, severe, or critical alarm threshold, the system issues an alarm to affected service modules or processes.

You can use the display memory command to display memory usage information.

If a memory alarm occurs, delete unused configuration items or disable some features to increase the free memory space. Because the memory space is insufficient, some configuration items might not be able to be deleted.

For more information about the thresholds, see Fundamentals Configuration Guide.

The system will restart if one of the following conditions is met:

· After a critical alarm occurs, the remaining free-memory value has been smaller than the critical alarm threshold for 30 seconds.

· The interval between two consecutive critical alarms is shorter than 30 seconds.

· The critical alarm has occurred three times within three minutes.

· After a critical alarm occurs, the system will periodically sample free memory space and predict if the free memory space will be exhausted within 30 seconds. If the prediction result indicates that the free memory space will be exhausted within 30 seconds, the system will restart.

Once the free memory space reaches the minor, severe, or critical alarm threshold, the device will display the current memory usage information when you log in to the device through console or Telnet login, or execute every command.

The sending periods of memory alarm notifications are as follows:

· If the free memory space has consistently exceeded the minor threshold for 12 hours, a minor alarm notification is sent.

· If the free memory space has consistently exceeded the severe threshold for 3 hours, a severe alarm notification is sent.

· If the free memory space has consistently exceeded the critical threshold for 1 hour, a critical alarm notification is sent.

cpu cpu-number: Specifies a CPU by its number.

ratio: Specifies DMA memory thresholds in percentage.

critical critical-value: Specifies the DMA memory alarm threshold. If the ratio keyword is specified, the value range for the critical-value argument is 1 to 100 in percentage. If the ratio keyword is not specified, the value range for the critical-value argument is 0 to 4194304.

normal normal-value: Specifies the normal state threshold. If the ratio keyword is specified, the value range for the normal-value argument is 1 to 100 in percentage. If the ratio keyword is not specified, the device adjusts the value for the normal-value argument depending on the value for the critical-value argument.

Usage guidelines

To ensure correct operation of the services that require DMA memory, the system monitors the amount of free DMA memory space regularly. If the amount of free DMA memory space decreases to or below the alarm threshold, the system generates a notification indicating that the DMA memory space is insufficient. If the amount of free DMA memory space increases above the normal state threshold, the system generates a notification indicating that the DMA memory space is sufficient.

If the resource type stays in minor alarm state or changes from severe alarm state to minor alarm state, the device identifies whether resending of minor resource depletion alarms is enabled. If the feature is disabled, the device does not issue additional minor alarms. If the feature is enabled, the device resends minor alarms periodically.

The resending interval of severe alarms is 24 hours and the resending interval of minor alarms is 7×24 hours.

Examples

# Enable resending of minor resource depletion alarms.

‌

slot slot-number: Specifies an IRF member device by its member ID.

cpu cpu-number: Specifies a CPU by its number.

by-percent: Specifies resource depletion thresholds in percentage.

minor-threshold minor-threshold: Specifies the minor resource depletion threshold. To view the value range, enter a question mark (?) in the place of the minor-threshold argument.

severe-threshold severe-threshold: Specifies the severe resource depletion threshold. To view the value range, enter a question mark (?) in the place of the severe-threshold argument.

Usage guidelines

After you execute this command for a resource type, the device monitors the available amount of the type of resources. The device samples the available amount at intervals, compares the sample with the resource depletion thresholds to identify the resource depletion status, and sends alarms as configured.

Examples

# Set the minor resource depletion threshold to 30% and the severe resource depletion threshold to 10% for ARP entry resources on slot 1.

Default

The port status detection timer setting is 30 seconds.

Views

System view

Predefined user roles

network-admin

Parameters

interval: Specifies the port status detection timer value in seconds. The value range is 0 to 300. The value of 0 indicates that port status detection is not automatically performed, and you need to execute the undo shutdown command to restore the port status manually.

Usage guidelines

In networks with loop detection or spanning tree protocols, some protocols automatically disable a port. For example, the MSTP module disables a BPDU-protected port upon receiving a configuration message. The device starts a port status detection timer when a port is shut down by a protocol. If the port has been in down state before the timer expires, the device will set the port status to the port's physical status.

If you change the timer setting during port detection, the device compares the new setting (T1) with the time that elapsed since the port was shut down (T).

If T < T1, the port will be brought up after T1 – T seconds.

If T ≥ T1, the port is brought up immediately.

For example, the timer setting is 30 seconds. If you change it to 10 seconds 2 seconds after the port is shut down, the port will come up 8 seconds later. If you change the timer setting to 2 seconds 10 seconds after the port is shut down, the port comes up immediately.

Examples

# Set the port status detection timer to 100 seconds.

lowlimit: Specifies the low-temperature threshold in Celsius degrees. The value range varies by temperature sensor. To view the value range, enter a question mark (?) in the place of this argument.

warninglimit: Specifies the high-temperature warning threshold in Celsius degrees. This threshold must be greater than the low-temperature threshold. To view the value range, enter a question mark (?) in the place of this argument.

alarmlimit: Specifies the high-temperature alarming threshold in Celsius degrees. This threshold must be greater than the warning threshold. To view the value range, enter a question mark (?) in the place of this argument.

Usage guidelines

When the device temperature drops below the low-temperature threshold or reaches the high-temperature warning or alarming threshold, the device performs the following operations:

· Sends log messages and traps.

· Sets LEDs on the device panel.

Examples

# Set temperature alarm thresholds for hotspot sensor 1 in a slot.
