Best Practices for Configuring DHCP

Cisco Network Registrar (CNR) is installed on the SPE310 running System Manager to provide Dynamic Host Configuration Protocol (DHCP) and Bootstrap Protocol (BOOTP) services for the Cisco ICS 7750 and other devices on the LAN to which the Cisco ICS 7750 is connected.

Caution CNR is not intended for use as a standalone software tool on the Cisco ICS 7750. Do not use the CNR CLI or graphical user interface (GUI) to invoke CNR commands on the Cisco ICS 7750.

Caution CNR is factory-installed on the SPE310 running System Manager. Do not attempt to use the CNR installation program to reinstall CNR on the SPE310 running System Manager, and do not attempt to install CNR on any other SPE310s in the chassis. If you are reimaging an SPE310 running System Manager, the Image Install Tool installs CNR automatically.

After the Cisco ICS 7750 has been configured (by running ICSConfig), CNR keeps track of devices that send BOOTP or DHCP requests. A configured SPE310 responds to a DHCP or BOOTP request if the device sending the request has a known MAC address or if the Client Identifier field in the DHCP request is set to a known value.

Installing or Enabling Microsoft DHCP Server on the SPE310 Running System Manager

By default, the Windows image provided with the SPE310 does not have the Microsoft DHCP Server enabled. You should not use the Windows Component Wizard to add or enable the Microsoft DHCP Server on the SPE310 running System Manager. Adding or enabling Microsoft DHCP Server on the SPE310 running System Manager causes a conflict with CNR.
