无线插卡做了热备,断电重启后,备AC上AP少了1000多个,具体故障显示如下,但是license总数是相同的。

1、首先检查设备的配置,设备上确实配置AC备份,
wlan ap-group default-group
priority 7
echo-interval 60
wlan tunnel-preempt enable
statistics-interval 60
retransmit-count 5
retransmit-interval 6
backup-ac ip 10.1.1.3
provision auto-update enable
2.现场AP注册用的是三层注册,检查DHCP的配置,主备AC的管理地址是正常下发的
<lfkfq_kejigu_ap04>dis dhcp client verbose
Vlan-interface1 DHCP client information:
Current state: BOUND
Allocated IP: 10.0.24.100 255.255.248.0
Allocated lease: 86400 seconds, T1: 32993 seconds, T2: 75600 seconds
Lease from Jan 9 10:10:24 2019 to Jan 10 10:10:24 2019
DHCP server: 10.0.24.1
Transaction ID: 0x58e8e48d
Default router: 10.0.24.1
Boot servers: 10.1.1.2 10.1.1.3
Client ID type: mac-address(type value=01)
Client ID value: ac74-09dc-3000
Client ID (with type) hex: 01ac-7409-dc30-00
3、让现场用一台在主AC上正常注册的,在备AC上注册不上的AP测试,去往主AC的管理地址10.1.1.2正常,但是ping不通备AC的管理地址10.1.1.3
4、 和工程师沟通,故障AP同网段的其他AP是在主备AC上正常注册的。现场有四个管理地址
Vlan120
up up
10.0.0.1 --
ap
Vlan130 up
up 10.0.8.1 --
AP
Vlan140 up
up 10.0.16.1 --
ap
Vlan150 up
up 10.0.24.1 --
AP
将备AC聚合四个口之后,所有的AP全部在备AC上成功注册。
