DHCP client configuration commands
The DHCP client configuration is supported only on Layer 3 Ethernet ports, VLAN interfaces, and Layer 3 aggregate interfaces.
When multiple VLAN interfaces having the same MAC address use DHCP for IP address acquisition via a relay agent, the DHCP server cannot be the Windows Server 2000 or Windows Server 2003.
You cannot configure an interface of an aggregation group as a DHCP client.
