Usage Guidelines

After IP unicast routing has been configured, you can configure the switch to forward DHCP or BOOTP requests coming from clients on subnets being serviced by the switch and going to hosts on different subnets.

To configure the relay function, follow these steps:

  1. Configure VLANs and IP unicast routing.
  2. Configure the addresses to which DHCP or BOOTP requests should be directed, using the following command: configure bootprelay add ip_address
  3. Enable the DHCP or BOOTP relay function using the following command: enable bootprelay


The following example configures BOOTP requests to be directed to

configure bootprelay add
