DHCP Client Configuration Example
Note:
The DHCP client configuration is supported only on VLAN interfaces.
When multiple VLAN interfaces with the same MAC address use DHCP for IP
address acquisition via a relay agent, the DHCP server cannot be a Windows 2000
Server or Windows 2003 Server.
You are not recommended to enable both the DHCP client and the DHCP Snooping
on the same device. Otherwise, DHCP Snooping entries may fail to be generated,
or the DHCP client may fail to obtain an IP address.
4.1 Introduction to DHCP Client
With the DHCP client enabled on an interface, the interface will use DHCP to obtain
configuration parameters such as an IP address from the DHCP server.
For S5500-EI series Ethernet switches (operating as DHCP clients), the vendor and
device information contained in Option 60 of DHCP requests is not configurable;
instead, it is determined by the application program of the switches. Refer to
for different information added in Option 60 based on device models.
