Accessing the System
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.
