The
dns-server
parameter controls DNS server IP addresses. Up to two DNS
servers are supported. See
“Configuring the Domain Name System Lookup
.
The
tftp-download
parameter controls two DHCP options: TFTP server IP
address and script file. Enabling this option causes a TFTP session to be created
and the script file to be downloaded and executed during startup.
The
time-server
parameter controls the IP address for a time server. Two time
servers are supported. This information is used by the SNTP service. See
“Managing an SNTP Server” on page 49
.
The
time-offset
parameter controls the time offset value that is used by the
SNTP service. See
“Managing an SNTP Server” on page 49
.
The TFTP server IP address and the script file are downloaded and executed
only during a startup. If the script on the server changes, it is not sent to the
node until the next time the node reboots or starts up.
If DNS and SNTP data on the DHCP server changes, then it is sent to the node
whenever the node renews DHCP information. The new DNS and SNTP data
then takes effect immediately.
In all cases, DNS and SNTP data provided by the DHCP server overrides any
data configured locally.
Configuration
Download Profile
With the configuration download profile you specify:
• the filename of the script file
• the server from which to get the script file
• a user-name and password
You can specify the server by either its IP address or its name. If both are
specified, the IP address has precedence. The default name is
belairconfig.com
.
The script file is downloaded and executed only during a startup. If the script on
the server changes, it is not sent to the node until the next time the node
reboots or starts up.
Pre-requisites
To use a configuration download profile, your server must be configured with
the appropriate user accounts and passwords. The account must contain a valid
script file.
