Collecting Other Information

(Mandatory) Checking Current Configuration on the AC

• Web system
  1. Choose Diagnosis > Diagnosis Tool > One-click Information Collection to access the One-click Information Collection page.
  2. Click One-click Collection. In the displayed dialog box, click OK.
  3. After the collection is complete, the system displays a dialog box. Click OK in the dialog box.
  4. The system displays the current collection file name and collection time.
  5. Click the export button to export the current collection file web_diaginfo.txt.

• CLI

  <AC> display current-configuration all  //Check current configuration.  
  <AC> display version  //Check version information. 
  <AC> display patch-information  //Check patch information.  
  <AC> compare configuration  // Compare the current configuration with the saved configuration to check whether they are the same.

  In V200R019C10 and later versions, the command lines are changed as follows:

  • display umac wcfg history record-number //Check historical configurations of an AP.
  • display umac wcfg global-cfg //Check the configuration of global variables on the WCFG module.
  • display umac wcfg radio-cfg radio-id //Check the configuration of a radio with a specified ID.
  • display umac wcfg vap-cfg radio radio-id vap vap-id //Check the configuration of a VAP with a specified ID.

Checking Historical Records of the Control Plane Configuration and Current Configuration on the AP

If the configuration delivered by the AC does not take effect or the actual values are not consistent with the configured values, collect the following information.

[AP-diagnose] display wsrv wcfg history record-number  //Check historical records of the AP configuration. 
[AP-diagnose] display wsrv wcfg global-cfg  //Check the configuration of global variables of the WCFG module.  
[AP-diagnose] display wsrv wcfg radio-cfg radio-id  //Check the configuration of a specified radio.  
[AP-diagnose] display wsrv wcfg vap-cfg vap-id  //Check the configuration of a specified VAP.  

Checking the Actual Configuration on the Wi-Fi Driver

In V200R019C00 and earlier version:

[AP-diagnose] iwconfig radio radio-id vap vap-id

• radio-id: 0-1. 0 indicates the 2.4 GHz radio, and 1 indicates the 5 GHz radio.
• vap-id: 0-15. Check the WLAN ID of the VAP profile bound to an AP radio on the AC, and determine the VAP ID through the formula: VAP ID = WLAN ID - 1

  If multiple VAPs are configured, check VAP IDs one by one.

For example, if the WLAN ID of the VAP profile bound to the 2.4 GHz radio is 1, run the following command to check the VAP ID.

[AP-diagnose] iwconfig radio 0 vap 0

In V200R019C10:

[AP-diagnose] display umac vap-config radio 1 vap 0
Radio type        :802.11ax

If the ESSID is displayed, the VAP is successfully created on the AP.

Collect statistics on error packets (for example, on an AP).

1. Enable debugging before collecting information.

   <AP> terminal debugging  
   <AP> terminal monitor  
   <AP> debugging timeout 0  
   [AP-diagnose] debugging cap error statistics

2. Collect statistics on error packets.

   [AP-diagnose] display cap all error statistics

3. After collecting information, disable debugging to avoid impact on the system performance.

   [AP-diagnose] undo debugging cap error statistics
   <AP> undo terminal debugging  
   <AP> undo terminal monitor

Collect statistics on forwarding events (for example, on an AP).

1. Enable debugging before collecting information.

   <AP> terminal debugging  
   <AP> terminal monitor  
   <AP> debugging timeout 0  
   [AP-diagnose] debugging cap event statistics

2. Collect statistics on forwarding events.

   [AP-diagnose] display cap all event statistics

3. After collecting information, disable debugging to avoid impact on the system performance.

   [AP-diagnose] undo debugging cap event statistics  
   <AP> undo terminal debugging  
   <AP> undo terminal monitor

Collecting Black Box Information

AC

[AC-diagnose] display inspect black-box record all process all

AP

[AP-diagnose] display inspect black-box record all

Collecting Memory Leak Information

Check which memory partition occupies a large size of memory, where a memory leak may occur. You can also periodically check whether the memory usage keeps increasing. If so, a memory leak may occur.

[AC-diagnose] display memory-usage
[AC-diagnose] display memory-linux
[AC-diagnose] display inspect mem-debug-info 1 0 0 0
[AC-diagnose] display inspect mem-debug-info 26 1 0xffffffff 0
[AC-diagnose] display inspect mem-debug-info 13 1 0 0

Collecting Restart Reason Information (Applicable to Both APs and ACs)

<AP> display reset-reason
<AP> system-view
[AP] diagnose
[AP-diagnose] display kernel-logbuf level 1
[AP-diagnose] display kernel-logbuf level 2
[AP-diagnose] display kernel-logbuf level 3
