At the monitor prompt, type “ping” and then specify the IP address of
the remote device. Specify the number of bytes per packet, and the
number of packets to be sent. The ping command display looks like
this:
monitor:: ping 134.141.72.165
PING 134.141.72.165: 64 data bytes
2.5 AUTO-INITIALIZING THE ROMS
The Micro-CS supports the BOOTP and RARP protocols. The ROMs use
these protocols to obtain boot information without requiring any manual
setup on the Micro-CS.
• BOOTP is a bootstrap protocol that allows a diskless client to
determine its Internet address, the Internet address of the server, and
the name of the file to be loaded into memory.
• RARP (Reverse Address Resolution Protocol) maps a hardware
address into an Internet address.
The ROMs invoke this system of acquiring boot information when a boot
is initiated and the Micro-CS’s Internet Address is not initialized. Under
this condition the Micro-CS first tries to get boot information via BOOTP;
if BOOTP fails, it tries to get boot information via RARP. If neither
protocol is successful, the Micro-CS either prompts the user for the
Internet address (if in SETUP mode) or it lights the ATTN LED to
indicate the Internet address is not set (if in Normal mode).
2.5.1 Retrieving Boot Information Using BOOTP
For a successful BOOTP retrieval a bootpd must be running on a host on
the same network as the Micro-CS and must have the appropriate
information in the bootptab file. The Micro-CS’s BOOTP
implementation adheres to rfc951, rfc1048, and rfc1084 specifications.
Below is a sample bootptab file entry used to initialize the Micro-CS
named terminator.
