5.3.2 System Status Monitoring
The NetBootLoader provides various functions for monitoring the overall status of the system
during the operation of the NetBootLoader. The following table provides an overview of avail-
able system status monitoring functions.
5.3.3 Network Accessing
To support application development and operational requirements for various boot strategies,
the NetBootLoader provides several functions for gaining access to network services. These
functions include: access to dhcp/bootp servers, accessing tftp servers, and accessing ftp
servers.
At initial startup of the VMP3, only the NetBootLoader is installed in onboard FLASH. To sup-
port application development or remote boot capability, the NetBootLoader can provide net-
working interfacing via the Ethernet port FCC1 (FE).
To achieve this, certain network parameters must first be configured. This can be done manu-
ally via a terminal or dynamically via the network. The command DHCP makes it possible to
download such parameters and to configure the Ethernet port FCC1 (FE) for network opera-
tion. Once the Ethernet port is configured, the commands TFTP and FTP are available to down-
load bootable images or other files as required.
5.3.3.1 dhcp/bootp Server Access
Use of this access method requires the availability of either a dhcp or bootp server in the same
network as the VMP3. The DHCP command causes the NetBootLoader to first attempt to es-
tablish contact with a DHCP server. If contact is not achieved, it then tries to contact a BootP
server. When contact is established, parameters required by the VMP3 are provided accord-
ingly and the Ethernet port is configured and then made available for normal operation.
In the event the VMP3 is reset or cold started the configuration parameters set by the above
method are lost. Only if the parameters have been set by the NET command are they still avail-
able.
Prior to using the "dhcp" command, the IP address of the VMP3 must be set to
255.255.255.255 using the "net" command.
