终结者注册问题经验分享

终结者AP方案相比传统的瘦AP架构，增加了“终结者AP本体”这个角色，每个房间仍然有一个分体AP覆盖，分体AP通过网线连接到本体AP，每个本体AP可以承接多个分体AP，为这些分体AP进行PoE供电的同时，也能够进行管理和维护。终结者AP具备上行接口，在部署过程当中可以发挥接入交换机的作用，与上行汇聚或者核心连接。当分体AP失去关联或者故障的时候可以在本体AP上发现和维护。分体AP部署在房间内，独立工作。相比传统的室分和放装方案，每个房间内的用户可独享单AP提供的带宽，可以充分的满足客户对高带宽的需求。需要注意的是分体AP只能采用本体PoE供电，不能使用其他设备供电！

1．本体无法注册

本体不占用license，注册不上主要有以下几种问题

1）本体是否获得正确的ip地址（dhcp无法获取，可以手工配置ip进行测试）

<AC>display wlan ap name 1010 address

AP name                         IP address                      MAC address

1010                            192.168.0.1                     600b-030f-4420

<WT1010>display dhcp client verbose

Vlan-interface1 DHCP client information:

  Current state: BOUND

  Allocated IP: 192.168.0.1 255.255.255.0

  Allocated lease: 86400 seconds, T1: 37615 seconds, T2: 75600 seconds

  Lease from Nov  1 13:54:25 2016   to   Nov  2 13:54:25 2016

  DHCP server: 192.168.0.111

  Transaction ID: 0xa2e497cf

  Default router: 192.168.0.100

  DNS servers: 8.8.8.8

  Client ID type: mac-address(type value=01)

  Client ID value: 600b-030f-4420

  Client ID (with type) hex: 0160-0b03-0f44-20

  T1 will timeout in 0 days 8 hours 44 minutes 2 seconds

2）本体到AC之间链路是否存在问题（丢包率要求小于0.1%，特别注意中间链路环路）

<AC或者WT1010>ping -s 1472 -f -c 1000 -a 192.168.0.17 192.168.0.100

Ping小包能通，大包不通可能会导致版本和map无法下发到AP

3）Dhcp option 43填写错误导致本体找不到AC，可以在本体上配置AC地址进行测试

[WT1010]wlan ac ip 192.168.0.111

4）检查AC上本体模板配置（核对型号和序列号）

 [AC-wlan-ap-1010]display this

#

wlan ap 1010 model WT1010

 serial-id 219801A0T9C166000141

2．分体无法上线

1）本体在线是分体上线的前提条件，必须优先保证

2）分体占用license，所以第一步要查看剩余的license是否足够

<AC>display wlan ap all

Total number of APs: 8

Total number of connected APs: 3

Total number of connected manual APs: 3

Total number of connected auto APs: 0

Total number of connected common APs: 1

Total number of connected WTUs: 1

Total number of inside APs: 0

Maximum supported APs: 512

Remaining APs: 510

Total AP licenses: 32

Remaining AP licenses: 30.75

3）检查AC上分体模板配置（核对型号和序列号）

[AC-wlan-ap-420h]display this

#

wlan ap 420h model WTU420H

 serial-id 219801A0WA9163Q05874

 vlan 1

 radio 1

  radio enable

  service-template lb

 radio 2

#

4）根据ap型号区分超瘦（version2）和直通（version1）模式

目前WTU420（H）只支持version2

WTU410（H）、WTU430（H）只支持version1

5）分体直通模式注册问题参考普通ap

直通模式分体需要拿地址、超瘦模式分体不需要ip地址

6）分体超瘦模式注册不上

A．首先保证本体在线，并且本体在线之后才能给分体供电

B．如果本体是直通模式或者切换模式之后没有重启，超瘦是无法注册的

<AC>dis wlan ap running-configuration ap-name 1010 | include version

  version 2

C．查看本体是否供电正常

[AC-wlan-ap-1010]dis this

#

wlan ap 1010 model WT1010

 serial-id 219801A0T9C166000141

 powerdown wtu-port 5  enable-------人为关闭5号口poe

#

[WT1010-probe]diag poe 1/0 all status ---不管有没有分体，只要本体在线，默认都是up

Port 1  Poe Status id UP.

Port 2  Poe Status id UP.

Port 3  Poe Status id UP.

Port 4  Poe Status id UP.

Port 5  Poe Status id DOWN.------------这个poe关闭了

Port 6  Poe Status id UP.

Port 7  Poe Status id UP.

Port 8  Poe Status id UP.

Port 9  Poe Status id UP.

Port 10 Poe Status id UP.

Poe proc ok

D．查看本体和分体之前是否存在链路问题（有条件最好进行替换测试） 

<1010>display interface WTU-Ethernet 1/0/1

E．查看分体是否上送本体驱动管理

F．查看驱动管理上报软件平台

3．如何查看超瘦AP本体与分体的对应关系

[AC]display wlan ap all //查看本体分体是否在线

通过ap verbose可以查看分体属于哪个本体。

<AC1>dis wlan ap name 1020-3f-407 verbose //查看分体详细信息

AP name                       : 1020-3f-407

AP ID                         : 396

Name of WT                    : 1020-3f   //关联本体的名字

MAC address of WT             : 50da-00be-fe80   //关联本体的mac地址

本体有专门的命令查看本体包含哪些分体，可以查看已经发出请求或者上线的分体。

[WT1020-4f-probe]dis wlan wtu all  //查看关联的分体，不管分体是否在AC上线

                                 WTU information

 State : I = Idle,      D = Discovery,   DT = Dtls,  J  = Join,   IL = ImageLoad

         C = Config,    DC = DataCheck,  R  = Run,   N/A = Invalid state

WTU name               AP ID   State   Model             Serial ID

SubSlot1               14      R       WTU420H           219801A0WA9162Q07052

SubSlot2               13      R       WTU420H           219801A0WA9162Q06113

SubSlot6               2       R       WTU420H           219801A0WA9162Q05002

SubSlot7               15      R       WTU420H           219801A0WA9162Q06249

SubSlot8               9       D       WTU420H           219801A0WA9162Q03768

如果在AC上某个分体无法注册、本体上看到某个分体一直不是R状态，很有可能是序列号或者mac地址配置错误！

3．AP verbose中的Last reboot reason都有哪些

Power on：AP上电重启

Hard reboot：使用reset按钮重启AP

Watchdog reboot：看门狗重启

Unknown reboot：未知原因重启

User soft reboot：通过命令行、SNMP、Web等管理手段重启AP

Kernel exception soft reboot：内核异常重启

Kernel deadloop soft reboot：内核死循环重启

Auto update soft reboot：版本自动升级后重启

Memory exhausted：内存耗尽重启

Other unknown soft reboot：其他软件原因重启

4．AP verbose中的Tunnel down reason都有哪些

N/A：无

Failed to create timer：AC创建定时器失败，AC主动断开连接

Neighbor dead timer expired：控制隧道保活定时器超时，AC主动断开连接

Request wait timer expired：AP上线过程中，AC等待请求消息定时器超时，AC主动断开连接

Data check timer expired：上线过程AP会发送数据报文，AC如果没有收到，AC主动断开连接

Failed to process data channel keep-alive message：AC处理处理数据隧道保活报文失败，AC主动断开连接

Failed to process request：AC处理请求报文失败，AC主动断开连接

AP was reset：AC下发reset指令，AC主动断开连接

AP was deleted：AC删除AP，AC主动断开连接

Failed to come online：AC处理AP上线过程中产生内部错误，AC主动断开连接

Serial number changed：AC上修改AP的serial-id, AC主动断开连接

MAC address changed：AC上修改AP的MAC地址, AC主动断开连接

Number of APs exceeded the limit：AP数量超出AC能力，AC主动断开连接

Processed join request in Run state：AC上定时器未超时前再次收到AP的请求上线报文，这种情况是指AP先主动断开连接，

Failed to create AP context：AC上创建AP上下文信息失败, AC主动断开连接

Received failure result code：CAPWAP状态机状态变迁时收到AP回复消息的结果码是失败，AC主动断开连接

Failed to retransmit message：AC下发AP关键信息超时无响应（一般是下发配置），AC主动断开连接

Failed to download image file：AC给AP下载版本失败, AC主动断开连接

Image file downloaded successfully：AP下载版本成功，AC主动断开连接，AP重启

File operation timer expired：AP下载版本是，AC获取版本文件失败，AC主动断开连接

Failed to add tunnel：AC上创建隧道失败，AC主动断开连接

Received WTP tunnel down event from AP：AC收到AP的隧道down事件（暂未使用）

Backup AC closed the backup tunnel：备份AC关闭备份隧道

Master and backup tunnel switchover：主备隧道切换

Failed to inherit configuration：继承配置失败（暂未使用）

AP authentication failed：AP认证失败，AC主动断开连接

5．如何快速查找最近哪些AP掉线了

<AC>display wlan ap connection record all

APName           IPaddress       Serial ID        State     Time              

--------------------------------------------------------------------------------

ap71             7.7.7.41        219801A0T78156A0 Run       2016-04-05 15:27:39

                                 0119

此命令按照AP状态最后变化的时间顺序显示，越靠上表示越近，Time表示AP状态最后变化的时间。

终结者结构上虽然区别于普通AP，但是排查思路基本与FIT AP一致。
