对于WLC而言,无论PC,还是phone终端,只要是发了DHCP的请求,WLC收到之后,都会分配DHCP地址。可能存在的 ...
这连个原因都不是,DHCP 地址池足够多,手机用过好几台来测试
Information About Configuring DHCP Proxy
When DHCP proxy is enabled on the controller, the controller unicasts DHCP requests from the client to the
configured servers. At least one DHCP server must be configured on either the interface associated with the
WLAN or the WLAN itself.
When DHCP proxy is disabled on the controller, those DHCP packets transmitted to and from the clients are
bridged by the controller without any modification to the IP portion of the packet. Packets received from the
client are removed from the CAPWAP tunnel and transmitted on the upstream VLAN. DHCP packets directed
to the client are received on the upstream VLAN, converted to 802.11, and transmitted through a CAPWAP
tunnel toward the client. As a result, the internal DHCP server cannot be used when DHCP proxy is disabled.
The ability to disable DHCP proxy allows organizations to use DHCP servers that do not support Cisco’s
native proxy mode of operation. It should be disabled only when required by the existing infrastructure.
