iSTAR Edge G2 Controller Installation and Configuration Guide 24

IP Management Tools

iSTAR Edge G2 controllers can be configured to accept IP addresses and device names from one of the following:

■ Local Dynamic Host Configuration Protocol (DHCP) server.

■ Windows Internet Naming Service (WINS).

■ Domain Name System (DNS) servers.

DHCP servers simplify IP management by automatically distributing an IP address to clients when they broadcast to the

DHCP server. DHCP servers can manage a range of IP addresses. WINS and DNS servers compliment DHCP address

assignment by providing name-to-IP address mapping.

Using NetBIOS and Fully Qualified Domain Names

Configurations where IP addresses are subject to change (leased DHCP addresses, for example) can connect to the C•CURE

system using the NetBIOS or fully qualified domain name (FQDN). The configuration must contain a WINS or DNS server, for

name/address resolution.

If you are not using DHCP, use the iSTAR Web Page to configure NetBIOS and FQDNs. If you specify a NetBIOS or FQDN

name for a C•CURE host, you must also use the iSTAR Web Page to supply the IP addresses of the DNS or WINS server.

Local Address Management

You can maintain local address management by configuring the iSTAR Edge G2 with locked IP addresses. Locked IP

addresses retain the iSTAR Edge G2 address that is specified locally or by a local Dynamic Host Configuration Protocol

(DHCP) server.

If you use locked IP addresses the iSTAR Edge G2 will only communicate across gateways using the configured IP address

and translated addresses are not accepted.

NOTE

Before locking an IP address, ensure it is not subject to translation and is accessible locally.

The example displayed in Figure 2 on Page 25 shows a locked iSTAR Edge G2 configuration. The System Manager configures

this cluster from the branch office.

1. Use PING to check communication to the exposed (translated) IP address from the Corporate Office.

2. Use the iSTAR Web Page to configure the master controller and lock the exposed C•CURE address.

3. Use the iSTAR Web Page to configure the member controllers and lock the local subnet address.

NOTE

ICU is only used as a discovery device. Use the iSTAR Web Page to configure and setup your iSTAR Edge G2.
