DHCP simulation feature of the access network

0

The Dynamic Host Configuration Protocol (DHCP) simulation feature supports remote service acceptance, avoiding a second site visit and lowering the O&M costs. It also supports remote fault locating to quickly determine the faulty network segment and preliminarily locate the fault. Then a work order is assigned to the maintenance personnel of the corresponding network. This can improve the efficiency and lower the O&M costs.

ARP proxy feature of the access network
When a PC sends an Address Resolution Protocol (ARP) request to another PC, the request is processed by the access device connected to the 2 PCs. This process is called ARP proxy. ARP proxy is often used for communication between the sub virtual local area networks (VLANs) in a super VLAN.

Reasons why the PC that has obtained an IP address from the DHCP server cannot access the Internet on S series switch
For S series switches (exclude S1700 switches), in normal situations, a PC can access the Internet after obtaining an IP address through DHCP. However, if the IP address is assigned by a bogus DHCP server, the PC cannot access the Internet with the incorrect IP address. If this problem occurs, you are advised to configure DHCP snooping on the Layer 2 access device or first DHCP relay agent from the device, to ensure that PCs can obtain correct IP addresses. - When you configure DHCP snooping on a Layer 2 access device, steps 1, 2, and 3 are mandatory and must be performed in sequence. - When you configure DHCP snooping on a DHCP relay agent, only steps 1 and 2 are required. 1. Enable DHCP snooping globally. [HUAWEI] dhcp enable [HUAWEI] dhcp snooping enable 2. Configure the interfaces connected to DHCP clients. Perform the configuration on all interfaces connected to DHCP clients. GE0/0/1 is used as an example. [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] dhcp snooping enable [HUAWEI-GigabitEthernet0/0/1] quit 3. Perform the configuration on interfaces connected to the DHCP server. GE0/0/2 is used as an example. [HUAWEI] interface gigabitethernet 0/0/2 [HUAWEI-GigabitEthernet0/0/2] dhcp snooping trusted [HUAWEI-GigabitEthernet0/0/2] quit
