Catalyst 9800无线控制器常见无线客户端连接问题故障排除

简介

本文档介绍最常见的无线客户端连接问题场景以及如何在Catalyst 9800无线控制器上解决这些问题。

先决条件

要求

Cisco 建议您了解以下主题：

• Cisco Catalyst 9800 系列无线控制器
• 无线控制器的命令行界面(CLI)访问

使用的组件

本文档中的信息基于Cisco IOS® XE Gibraltar 16.10或更高版本的软件和硬件版本。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。

收集日志

WLC 9800 提供无间断跟踪功能。这可确保持续记录所有客户端连接相关的错误、警告和通知级别消息，并且您可以在发生事故或故障情况后查看其日志。

注：根据生成的日志量，您可以返回几小时到几天。

为了查看9800 WLC在默认情况下收集的跟踪，您可以通过SSH/Telnet连接到9800 WLC并遵循以下步骤（确保会话记录到文本文件）。

步骤1:检查控制器当前时间，以便您可以在问题发生之前的时间跟踪日志。

# show clock

第二步：根据系统配置的指示，从控制器缓冲区或外部系统日志收集系统日志。这样可以快速查看系统的运行状况和错误（如果有）。

# show logging

第三步：验证是否启用了任何调试条件。

# show debugging
IOSXE Conditional Debug Configs:

Conditional Debug Global State: Stop

IOSXE Packet Tracing Configs:


Packet Infra debugs:

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

注：如果看到列出了任何条件，则意味着遇到启用条件（mac地址、ip地址等）的所有进程的跟踪将记录到调试级别。这会增加日志量。因此，建议在非主动调试时清除所有条件.

第四步：假设在步骤3中，未将所测试的mac地址列为条件，请收集特定mac地址的始终在线通知级别跟踪。

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

您可以显示会话内容，也可以将文件复制到外部 TFTP 服务器。

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

条件调试和无线电活动跟踪：

如果永远在线(always-on)跟踪不能为您提供足够的信息来确定所调查问题的触发器，则可以启用条件调试并捕获无线活动(RA)跟踪，该跟踪为与指定条件（本例中为客户端MAC地址）交互的所有进程提供调试级别跟踪。要启用条件调试，请检查以下步骤。

第五步：确保未启用调试条件。

# clear platform condition all

第六步：为要监控的无线客户端MAC地址启用调试条件。

此命令开始监控提供的mac地址达30分钟（1800秒）。您可以选择延长监控时间，最多监控 2085978494 秒。

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

  

注意:要一次监控多个客户端，请对每个mac地址运行debug wireless mac  命令。

注意:您不会在终端会话上看到客户端活动的输出，因为所有内容都在内部缓冲，供以后查看。

步骤 7.重现要监控的问题或行为。

步骤 8如果在默认或配置的监控器时间开启之前重现问题，则停止调试。

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

一旦监控时间过长或调试无线停止，9800 WLC将生成一个本地文件，其名称为：

ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

步骤 9 收集 MAC 地址活动的文件。   您可以将复制到 ra trace  .log外部服务器，也可以直接在屏幕上显示输出。

检查 RA 跟踪文件的名称。

# dir bootflash: | inc ra_trace

将文件复制到外部服务器：

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

显示内容：

# more bootflash:ra_trace_MAC_aaaabbbbcccc_HHMMSS.XXX_timezone_DayWeek_Month_Day_year.log

步骤 10如果根本原因仍不明显，请收集内部日志，这些日志是调试级别日志的更详细视图。您无需再次调试客户端，因为这样只是进一步详细查看已收集并内部存储的调试日志。

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

注意：此命令输出返回所有进程的所有日志记录级别的跟踪，而且数量相当大。与Cisco TAC联系，以帮助分析这些跟踪。

您可以将复制到ra-internal-FILENAME.txt外部服务器，也可以直接在屏幕上显示输出。

将文件复制到外部服务器：

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

显示内容：

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

步骤 11删除调试条件。

# clear platform condition all

注意：请确保在进行故障排除会话后始终删除调试条件。

客户端无法连接时的场景

Web身份验证凭据无效

日志示例：

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

理由：

• 客户端未使用有效凭据
• 9800 WLC上未定义默认授权网络

可能的解决方案：

• 确保客户端正在使用有效的凭据
• 添加默认授权网络方法

GUI:

导航到Configuration > Security > AAA > AAA Method List > Authorization > + Add并使用这些参数创建新的授权方法。

CLI：

# config t
# aaa authorization network default local

策略配置文件中未定义有效的VLAN

日志示例：

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

理由：

在分配给WLAN的策略配置文件中没有定义有效的VLAN。

解决方案：

1.验证客户端使用哪个策略配置文件。

GUI:

导航到Monitoring > Wireless > Clients > Client row > Client Properties（使用特定客户端的mac地址进行可选搜索）。

CLI：

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

2.检验为该策略配置文件分配了哪个VLAN。

GUI:

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

CLI：

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

3.确保VLAN参数具有有效且活动的VLAN名称或VLAN ID。

GUI:

导航至Configuration > Layer2 > VLAN > VLAN。

CLI：

# show vlan brief

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Te0/0/2, Te0/0/3
210  VLAN0210                         active
1002 fddi-default                     act/unsup
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名称，则它区分大小写，因此请确保与命令上显示的名称完全相 show vlan brief同。

4.根据需要修复VLAN。

GUI:

导航回Configuration > Tags & Profiles > Policy > Policy Profile row > Access Policies并修复VLAN。

CLI：

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

错误密码

日志示例：

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

理由：

客户端输入了错误的密码。

可能的解决方案：

• 修复终端设备中的密码
• 修复SSID上的密码

GUI:

导航到 Configuration > Wireless > WLANs > WLAN name > Security > Layer2,然后修复密码。

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发送的访问控制列表(ACL)

理由：

9800 WLC上不存在RADIUS服务器发送的ACL。

可能的解决方案：

• 修复RADIUS服务器配置以发送正确的ACL名称
• 将缺少的ACL添加到9800 WLC 

RADIUS发送的VLAN在9800 WLC上不存在

理由：

9800 WLC上不存在RADIUS服务器发送的VLAN。

可能的解决方案：

• 修复RADIUS服务器配置以发送正确的VLAN名称/ID
• 将缺少的VLAN添加到9800 WLC 

由于WLAN或策略配置文件中的更改而断开连接

理由：

在GUI中进行了更改，或者手动禁用了SSID或策略配置文件。

解决方案：

这是正常行为，请避免在生产时间更改SSID或策略配置文件。

理由：

客户端已通过CLI从网络中手动删除：

无，用户发起的正常行为。

理由：

在EAP-Request Timeout间隔内和EAP-Request Max Retries时间内，客户端未响应9800 WLC发送的可扩展身份验证协议(EAP)数据包。

可能的解决方案：

• 将无线客户端驱动程序更新为最新驱动程序
• 确保无线客户端信任RADIUS的证书
• 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: 

导航至Configuration > Security > Advanced EAP并自定义所需的设置。

由于AP无线电重置，已断开连接

理由：

与客户端关联的AP更改了信道或电源，导致无线电重置。

可能的解决方案：

• 这是正常行为
• 您可以配置9800 WLC进行信道更改的频率 

CLI：

# config t

理由：

客户端已达到其会话超时。

可能的解决方案：

• 这是正常行为
• 增加与SSID关联的策略配置文件会话超时

CLI：

# config t
# wireless profile policy <policy-profile-name>
# shutdow
# session-timeout <20-86400 seconds>

GUI:

根据需要导Configuration > Tags & Profiles > Policy > Policy Profile Name > Advanced > WLAN Timeout航到并自定义计时器。

理由：

客户端在配置的空闲超时间隔内未发送流量（或足够流量）。

可能的解决方案：

• 这是正常行为
• 自定义与SSID关联的策略配置文件空闲设置

CLI：

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

GUI:

根据需要导Configuration > Tags & Profiles > Policy > Policy Profile Name > Advanced > WLAN Timeout航至并自定义空闲设置。

注:如果不配置空闲阈值，则客户端需要发送空闲超时期限内的任意流量量才能不断开连接。如果配置空闲阈值，则客户端必须在空闲超时内发送该数量的字节才能不断开连接（即，将空闲阈值配置为10个字节，空闲超时配置为30秒，无线客户端需要每30秒至少发送10个字节的流量才能不与网络断开连接）。
