WX3024H集中式转发,AC上建立DHCP地址池,AP网段VLAN18,客户端获取17段IP,但实际有的会获取到VLAN1,是哪里设置导致
dhcp server ip-pool 1
gateway-list 192.168.18.252
network 192.168.18.0 mask 255.255.255.0
address range 192.168.18.51 192.168.18.250
dns-list 202.96.128.86 114.114.114.114
#
dhcp server ip-pool vlan17
gateway-list 192.168.17.1
network 192.168.17.0 mask 255.255.255.0
address range 192.168.17.51 192.168.17.250
dns-list 202.96.128.86 114.114.114.114
AC旁挂核心,AP接在核心下面的POE交换机上
最佳答案
看你得截图是漫游信息啊,没看见错误啊,如果从终端看见获取得地址不是地址池中的地址,建议排查poe交换机下面是否接了路由器等存在dhcp服务的设备,如果存在,在接入设备上需要开启DHCP snooping

这个就是DHCP获取到的错误信息 MAC address : f460-e26d-fe40 IPv4 address : N/A IPv6 address : N/A Username : N/A AID : 1 AP ID : 3 AP name : 88df-9eb9-f700 Radio ID : 2 SSID : DYWIFI BSSID : 88df-9eb9-f710 VLAN ID : 17 Sleep count : 1 Wireless mode : 802.11gn Channel bandwidth : 20MHz 20/40 BSS Coexistence Management : Not supported SM power save : Disabled Short GI for 20MHz : Supported Short GI for 40MHz : Not supported STBC RX capability : Supported STBC TX capability : Not supported LDPC RX capability : Not supported Block Ack : TID 0 In Supported HT MCS set : 0, 1, 2, 3, 4, 5, 6, 7 Supported rates : 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps QoS mode : WMM Listen interval : 1 RSSI : 19 Rx/Tx rate : 24/1 Authentication method : Open system Security mode : RSN AKM mode : PSK Cipher suite : CCMP User authentication mode : Bypass Authorization ACL ID : N/A Authorization user profile : N/A Roam status : N/A Key derivation : SHA1 PMF status : N/A Forwarding policy name : N/A Online time : 0days 0hours 31minutes 47seconds FT status : Inactive
这是获取到1段的IP MAC address : 8cf2-287f-493e IPv4 address : 192.168.1.1 IPv6 address : N/A Username : N/A AID : 2 AP ID : 9 AP name : 88df-9eb9-bfc0 Radio ID : 2 SSID : DYWIFI BSSID : 88df-9eb9-bfd0 VLAN ID : 17 Sleep count : 0 Wireless mode : 802.11gn Channel bandwidth : 20MHz 20/40 BSS Coexistence Management : Not supported SM power save : Disabled Short GI for 20MHz : Supported Short GI for 40MHz : Not supported STBC RX capability : Not supported STBC TX capability : Not supported LDPC RX capability : Not supported Block Ack : TID 0 Both TID 1 In TID 2 In TID 3 In TID 5 In TID 6 In TID 7 In Supported HT MCS set : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 Supported rates : 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps QoS mode : WMM Listen interval : 1 RSSI : 16 Rx/Tx rate : 7.2/1 Authentication method : Open system Security mode : RSN AKM mode : PSK Cipher suite : CCMP User authentication mode : Bypass Authorization ACL ID : N/A Authorization user profile : N/A Roam status : Intra-AC roam Key derivation : SHA1 PMF status : N/A Forwarding policy name : N/A Online time : 0days 2hours 1minutes 54seconds FT status : Inactive
那就排查dhcp服务器,看看所有接入设备上有没有存在路由器或者dhcp服务器类似的设备
poe交换机打了pvid吗,pvid为18
