Catalyst 9800無線控制器常見無線客戶端連線問題故障排除

簡介

本檔案介紹最常見的無線使用者端連線問題案例，以及如何在Catalyst 9800無線控制器上解決這些問題。

必要條件

需求

思科建議您瞭解以下主題：

• Cisco Catalyst 9800 系列無線控制器
• 對無線控制器的命令列介面(CLI)訪問

採用元件

本檔案中的資訊是根據Cisco IOS® XE直布羅陀版16.10或更新軟體和硬體版本。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。

收集日誌

WLC 9800 提供永不間斷的追蹤功能。這可確保所有與客戶端連線相關的錯誤、警告和通知級別消息均持續記錄，並且您可以在發生事故或故障情況後檢視其日誌。

附註：根據生成的日誌量，您可以返回幾小時到幾天。

若要檢視9800 WLC在預設情況下蒐集的追蹤，可以透過SSH/Telnet連線到9800 WLC，然後按照以下步驟操作（確保作業階段已記錄到文字檔中）。

步驟1.檢查控制器當前時間，以便您可以跟蹤問題發生時的記錄時間。

# show clock

步驟 2. 從控制器的緩衝區或系統組態指定的外部系統日誌來收集系統日誌。這樣可以快速檢視系統的運行狀況和錯誤（如果有）。

# show logging

步驟 3. 確認所有偵錯條件是否已啟用。

# show debugging
IOSXE Conditional Debug Configs:

Conditional Debug Global State: Stop

IOSXE Packet Tracing Configs:


Packet Infra debugs:

Ip Address                                               Port
------------------------------------------------------|----------

附註：如果您看到列出任何條件，就表示遇到啟用條件（mac位址、ip位址等）的所有進程的追蹤都會記錄到偵錯層級。 這將增加日誌量。因此，建議在不主動調試時清除所有條件。

步驟4.假設步驟3中未列出所測試的mac地址作為條件。收集特定mac地址的始終開啟的通知級別跟蹤。

# show logging profile wireless filter { mac | ip } { <aaaa.bbbb.cccc> | <a.b.c.d> } to-file always-on-<FILENAME.txt> 

您可顯示作業階段中的內容，或可將檔案複製到外部 TFTP 伺服器。

# more bootflash:always-on-<FILENAME.txt>
or
# copy bootflash:always-on-<FILENAME.txt> tftp://a.b.c.d/path/always-on-<FILENAME.txt> 

條件調試和無線電活動跟蹤：

如果永遠線上(always-on)跟蹤未為您提供足夠的資訊來確定所調查問題的觸發因素，則可以啟用條件調試並捕獲無線活動(RA)跟蹤，該跟蹤為與指定條件（本例中為客戶端mac地址）互動的所有進程提供調試級別跟蹤。 若要啟用條件調試，請檢查以下步驟。

步驟5.確保未啟用調試條件。

# clear platform condition all

步驟 6. 針對您想要監控的無線用戶端 MAC 位址啟用偵錯條件。

此命令開始監控提供的mac地址達30分鐘（1800秒）。 您可選擇將此時間增加至 2085978494 秒。

# debug wireless mac <aaaa.bbbb.cccc> {monitor-time <seconds>}

  

注意:為了同時監控多個客戶端，請對每個mac地址運行debug wireless mac  命令。

注意:您看不到終端會話上客戶端活動的輸出，因為所有內容都在內部緩衝，供以後檢視。

步驟 7. 重現您想要監控的問題或行為。

步驟 8. 如果問題在預設或設定的監控時間結束之前重現，請停止偵錯。

# no debug wireless mac <aaaa.bbbb.cccc>

監控時間過後或偵錯無線功能停止後，9800 WLC會產生具有以下名稱的本地檔案：

ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

步驟9.收集mac地址活動的文件。您可以將複製複製到外部伺服器 ra trace  .log，或者直接在螢幕上顯示輸出。

檢查 RA 追蹤檔案的名稱。

# dir bootflash: | inc ra_trace

將檔案複製到外部伺服器：

# copy bootflash:ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log tftp://a.b.c.d/ra-FILENAME.txt

顯示內容：

# more bootflash:ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

步驟10.如果根本原因仍不明顯，請收集內部日誌，這些日誌是調試級別日誌的更詳細檢視。您無需再次調試客戶端，因為這只是進一步詳細檢視已收集並在內部儲存的調試日誌。

# show logging profile wireless internal filter { mac | ip } { <aaaa.bbbb.cccc> | <a.b.c.d> } to-file ra-internal-<FILENAME>.txt

附註：此命令輸出會傳回所有程序之所有記錄層級的追蹤，且資訊相當大量。聯絡Cisco TAC以幫助分析這些跟蹤。

您可以將複製到ra-internal-FILENAME.txt外部伺服器，或者直接在螢幕上顯示輸出。

將檔案複製到外部伺服器：

# copy bootflash:ra-internal-<FILENAME>.txt tftp://a.b.c.d/ra-internal-<FILENAME>.txt

顯示內容：

# more bootflash:ra-internal-<FILENAME>.txt

步驟 11. 移除偵錯條件。

# clear platform condition all

附註：請確保在進行故障排除會話後始終刪除調試條件。

客戶端無法連線的情況

Web身份驗證憑據無效

日誌示例：

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-2}{1}: [auth-mgr] [27915]: UUID: 100000000015b, ra: 15, (info): [e4b3.1851.90ff:capwap_90800003] Authc failure from WebAuth, Auth event fail

原因：

• 客戶端未使用有效憑據
• 9800 WLC上未定義預設授權網路

可能的解決方案：

• 確保客戶端正在使用有效的憑據
• 新增預設授權網路方法

GUI:

導航到Configuration > Security > AAA > AAA Method List > Authorization > + Add並使用這些引數建立新的授權方法。

CLI:

# config t
# aaa authorization network default local

策略配置檔案中未定義有效的VLAN

日誌示例：

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [epm] [25054]: UUID: 1000000000019, ra: 15, (ERR): EPM_PLUGIN_VLAN_ERR: [HDL = 0x0] Unable to get active_feature_ctx for vlan group name
YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [sanet-shim-miscellaneous] [25054]: UUID: 1000000000019, ra: 15, (ERR): MAC: 0874.0277.1345  Error in fetching vlans
YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-0}{1}: [sanet-shim-miscellaneous] [25054]: UUID: 1000000000019, ra: 15, (ERR): MAC: 0874.0277.1345  building Mobile Announce Vlanid payload failed

原因：

在分配給WLAN的策略配置檔案中沒有定義有效的VLAN。

解決方案：

1.驗證客戶端使用的是哪個策略配置檔案。

GUI:

導覽至Monitoring > Wireless > Clients > Client row > Client Properties（使用特定使用者端的mac位址進行選擇性搜尋）。

CLI:

# show wireless client mac-address <aaaa.bbbb.cccc> detail | inc Policy Profile
Policy Profile : default-policy-profile

2.檢驗分配給該策略配置檔案的VLAN。

GUI:

導航至Configuration > Tags & Profiles > Policy > Policy Profile row > Access Policies。

CLI:

# show wireless profile policy detailed default-policy-profile | inc VLAN
VLAN                          : VLAN2686

3.確保VLAN引數具有有效且活動的VLAN名稱或VLAN ID。

GUI:

導航至Configuration > Layer2 > VLAN > VLAN。

CLI:

# show vlan brief

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Te0/0/2, Te0/0/3
210  VLAN0210                         active

1003 token-ring-default               act/unsup
1004 fddinet-default                  act/unsup
1005 trnet-default                    act/unsup

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
2600 VLAN2600                         active
2601 VLAN2601                         active
2602 VLAN2602                         active
2686 VLAN2686                         active

注意:如果使用VLAN名稱，則其區分大小寫，因此請確保該名稱與命令上顯示的名稱完全相 show vlan brief同。

4.根據需要修復VLAN。

GUI:

導覽回Configuration > Tags & Profiles > Policy > Policy Profile row > Access Policies並修正VLAN。

CLI:

# config t
# wireless profile policy default-policy-profile
# shutdown
# vlan <vlan-# or vlan-name>
# no shutdown

密碼錯誤

日誌示例：

YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-1}{1}: [client-keymgmt] [27782]: UUID: 1000000000088, ra: 15, (ERR): MAC: e4b3.187c.3058  Keymgmt: Failed to validate eapol mic. MIC mismatch.
YYYY/DD/MM HH:MM:SS.xxx {wncd_x_R0-1}{1}: [client-keymgmt] [27782]: UUID: 1000000000088, ra: 15, (ERR): MAC: e4b3.187c.3058  Keymgmt: Failed to validate eapol key m2. MIC validation failed

原因：

客戶端輸入了錯誤的密碼。

可能的解決方案：

• 修復終端裝置中的密碼
• 修復SSID上的密碼

GUI:

導航到 Configuration > Wireless > WLANs > WLAN name > Security > Layer2，然後修復密碼。

CLI:

# config t
# wlan <wlan-name>
# shut
# security wpa psk set-key ascii 0 <clear-text-password>
# no shut

9800 WLC上不存在RADIUS傳送的存取控制清單(ACL)

原因：

9800 WLC上不存在RADIUS伺服器傳送的ACL。

可能的解決方案：

• 修復RADIUS伺服器配置以傳送正確的ACL名稱
• 將遺失的ACL新增到9800 WLC 

9800 WLC上不存在RADIUS傳送的VLAN

9800 WLC上不存在RADIUS伺服器傳送的VLAN。

可能的解決方案：

• 修復RADIUS伺服器配置以傳送正確的VLAN名稱/ID
• 將遺失的VLAN新增到9800 WLC 

由於WLAN或策略配置檔案中的更改而斷開連線

原因：

在GUI中進行了更改，或者手動禁用了SSID或策略配置檔案。

解決方案：

這是正常行為，請避免在生產時間更改SSID或策略配置檔案。

從網路中手動刪除客戶端

原因：

在EAP-Request Timeout間隔內和EAP-Request Max Retries時間內，客戶端未響應9800 WLC傳送的可擴展身份驗證協定(EAP)資料包。

可能的解決方案：

• 將無線客戶端驅動程式更新為最新驅動程式
• 確保無線客戶端信任RADIUS的證書
• 增加EAP-Request Timeout和/或EAP-Request Max Retries

CLI:

# config t
# wireless security dot1x request retries <0-20>
# wireless security dot1x timeout <1-120 seconds>

GUI: 

導覽至Configuration > Security > Advanced EAP並自訂所需的設定。

原因：

與客戶端關聯的AP更改了通道或電源，導致無線電重置。

可能的解決方案：

• 這是正常行為
• 您可以設定9800 WLC進行通道變更的頻率 

CLI:

# config t
# ap dot11 { 5ghz | 24ghz } rrm channel dca interval <0-24>

原因：

客戶端在配置的空閒超時時間間隔內沒有傳送流量（或足夠的流量）。

可能的解決方案：

• 這是正常行為
• 自定義與SSID關聯的策略配置檔案空閒設定

CLI:

# config t
# wireless profile policy <policy-profile-name>
# shutdow
# idle-timeout <15-100000 seconds>
# idle-threshold  <0-4294967295 bytes> 
# no shutdown

GUI:

根據需要導Configuration > Tags & Profiles > Policy > Policy Profile Name > Advanced > WLAN Timeout航到並自定義空閒設定。

註:如果未配置空閒閾值，則客戶端需要傳送空閒超時時間段內的任何流量才能不斷開連線。如果配置了idle-threshold，則客戶端必須在空閒超時內傳送該數量的位元組才能不斷開連線（即，配置了10位元組的空閒閾值和30秒的空閒超時，無線客戶端需要每30秒至少傳送10位元組的流量才能不斷開與網路的連線）。
