IBM Hardware Management Console Installing And Configuring page 33

Hardware Management Console (HMC). The assigned network mask is used to generate
a unique address, by default, for the local private LAN. If the nodes will be connected
into a larger network with an administered TCP/IP address, you can specify the TCP/IP
address to be used. The default is generated by the system.
Firewall Settings
HMC firewall settings create a security barrier that allows or denies access to specific
network applications on the HMC. You can specify these control settings individually for
each physical network interface, allowing you control over which HMC network
applications can be accessed on each network.
If you have configured at least one adapter as an Open network adapter, you must provide the following
additional information to enable your HMC to access the LAN:
Local host information
HMC host name:
Domain name:
Description of HMC:
Gateway information
Gateway Address: (nnn.nnn.nnn.nnn)
Gateway device:
DNS enablement
Do you want to use DNS? (yes/no)
If "yes", specify DNS Server Search Order below:
1.
2.
Domain suffix search order:
1.
2.
Local Host Information
To identify your Hardware Management Console (HMC) to the network, enter the HMC's host
name and domain name. Unless you are using only short host names on your network, enter a
fully qualified host name. Domain name example: name.yourcompany.com
Gateway Information
To define a default gateway, fill in the TCP/IP address to be used for routing IP packets. The
gateway address informs each computer or network device when to send data if the target station
is not located on the same subnet as the source.
DNS Enablement
The Domain Name System (DNS) is used to provide a standard naming convention for locating
IP-based computers. By defining DNS servers, you can use host names to identify servers and
Hardware Management Consoles (HMCs) rather than IP addresses.
DNS Server Search Order
Enter the IP addresses of DNS servers to be searched for mapping the host names and IP
addresses. This search order is available only when DNS is enabled.
Domain Suffix Search Order
Enter the domain suffixes you are using. The HMC uses domain suffixes to append to
unqualified names for DNS searches. Suffixes are searched in the order in which they are listed.
This search order is available only when DNS is enabled.
