H3C S7500E Series Ethernet Switches

Chapter 2 DHCP Relay Agent Configuration

Commands

2-10

Description

Use the dhcp select relay command to enable the relay agent on the current interface,

specified or all interfaces. Upon receiving requests from an enabled interface, the relay

agent will forward these requests to outside DHCP servers for IP address allocation.

Use the undo dhcp select relay command to restore the default on interface(s).

After DHCP is enabled, the DHCP server is enabled on an interface by default. That is,

upon receiving a client’s request from the interface, the DHCP server allocates an IP

address from the DHCP address pool to the client.

Examples

# Enable the DHCP relay agent on VLAN-interface 1.

[Sysname] interface vlan-interface 1

[Sysname-Vlan-interface1] dhcp select relay
