Configuration Guidelines

The guidelines in this section apply to SEFOS DHCP configurations.

Refer to the Sun Ethernet Fabric Operating System CLI Base Reference Manual for the complete set of commands and the various options available for configuring DHCP.

DHCP Client

The DHCP server must assign an IP address to the router interface. If it does not, the DHCP renew command fails and displays the following error message:

Interface does not have a DHCP originated address

DHCP Relay Agent

The following requirements must be satisfied for the DHCP relay agent to work properly:

  • The DHCP server must be disabled before enabling the DHCP relay agent.

  • The relay agent must be enabled in order to become active.

Once the relay agent becomes active, it forwards the packets from the client to a DHCP server. The relay agent also performs any processing related to relay agent information options, such as inserting the necessary options while relaying a packet from a client to a server, and examining or stripping options when relaying a packet from a server to a client.

DHCP Server

The DHCP server has the following requirement and assumption about pool address assignment:

  • DHCP relay must be disabled before enabling the DHCP server.

  • The DHCP server assumes that all pool addresses may be assigned to clients.
