This document describes DHCP relay on Cisco ASA with the help of packet captures and debugs, and provides a configuration example.
Note: For DHCP VLAN Relay, the DHCP server will assign IP addresses of the same subnet to both VLAN 10 and VLAN 20, although the clients belong to different VLANs. The subnet of the addresses to be assigned is determined by the subnet that the default relay agent interface is in, so h...
使用dhcp relay server-ip命令来指定DHCP服务器的IP地址。例如: plaintext dhcp relay server-ip 192.168.254.2 这将告诉DHCP中继设备,所有来自该VLAN的DHCP请求都应该转发到IP地址为192.168.254.2的DHCP服务器上。 保存并应用配置: 完成配置后,记得保存配置并应用更改。在CLI中,可以使用以下命令来保存配置: plaintex...
A DHCP relay agent is a small program that relays DHCP/BOOTP messages between clients and servers on different subnets. To support and use DHCP service across multiple subnets, the router(s) that connect each subnet must support DHCP/BOOTP relay agent capabilities. For more information see –...
We configure a DHCP relay agent only on the interface that is directly connected to a local subnet. In this network, four interfaces are directly connected to the local subnets. These interfaces are the following. To configure the above-listed interfaces as DHCP relay agents, use the'ip helper...
Ensure that the FTD is registered to the FMC before you start to configure the DHCP Server/Relay. Verify the connectivity to DHCP server in DHCP Relay configuration. > system support diagnostic-cli Attaching to ASA console ... Press 'Ctrl+a then d' to detach. ...
Till now, all the configuration about the DHCP Relay is done. Let’s check if it does work. Step 7: Connect the PC to the ports belong to different VLANs, for example PC1 to port 1/0/4 and PC2 to 1/0/3. Then run the CMD, input the command:ipconfig/release and ipconfig/renew...
In your Azure VMware Solution private cloud, under Workload Networking, select DHCP > Add. Select either DHCP Server or DHCP Relay and then provide a name for the server or relay and three IP addresses. Note For DHCP relay, you only require one IP address for a successful configuration. ...
A DHCP relay agent is an RFC 1542 compliant device that forwards DHCP broadcast traffic to other subnets that hosts a DHCP server.Tip You can implement DHCP relay by using a Windows Server installed with Routing and Remote Access.You do not need to assign all IP...
