one of the clients won't receive the DHCP Offer. I verified that the DHCP server receives the DHCP Discover and replies with the DHCP Offer, which makes it through the router. But the WLC debugging does not show the offer; only continuous DCHP Discover from...
DHCP client lease information on interface if1 接口if1上的DHCP客户端的租约信息。 Current machine state 显示设备当前状态信息,可能的取值包括: Halt:停止申请IP地址状态。 Init:初始化状态。 Waiting offer:等待OFFER状态。 Selecting:发送DHCP DISCOVER报文寻找DHCP服务器后,进入该状态,等待DHCP服务器的响应报文。
If the value of DHCP Offer is not 0 but the value of DHCP Request is 0, the DHCP client does not respond to the DHCP Offer packet sent by the DHCP server. In this case, check the link between the DHCP client and DHCP server or check the client status. If the values of all items...
In the operational logs provided, you can see that the WLC is receiving the DHCP Discover message from the wireless client, and the client's VLAN is relaying it to the helper address (which in the example provided is the internal loopback interface). Following t...
back to the client. The ip address would be included inside the DHCPOFFER message, but not used as a destination ip address, instead the server uses the client mac address as the destination L2 address. Once the client receives the DHCPOFFER message, the process goes further to be completed...
(DHCPNak). The DHCPNak message occurs when the IP address requested is not available or the client has been physically moved to a different subnet that requires a different IP address. After receiving a DHCPNak message, the client returns to the Initializing state and begins the lease process...
BitLocker 网络解锁客户端发送的第三条消息没有消息类型选项。 DHCP 服务器将消息视为 BOOTP 请求。 支持BOOTP 客户端的 DHCP 服务器必须根据 BOOTP 协议与这些客户端进行交互。 服务器必须创建 BOOTP BOOTREPLY 消息,而不是 DHCP DHCPOFFER 消息。 换句话说,服务器不得包含 DHCP 消息选项类型,并且不...
ip dhcp smart-relay Enables the Cisco IOS DHCP relay agent to switch the gateway address (giaddr field of a DHCP packet) to secondary addresses when there is no DHCPOFFER message from a DHCP server ip helper-address Forwards UDP broadcasts, including BOOTP, received on an interface. ip dhcp...
Also, the client must have logic that lets it “time out” if it receives no reply to sent messages in various states, such as not receiving any offers in the SELECTING state. The next few topics discuss these matters in more detail....
