Updating Software TCP/IP
D-2
TCP/IP
Before the MSS downloads the new software, it will send DHCP, BOOTP, and/or RARP queries (all are
enabled by default). Next, the MSS will attempt to download the MSS4.SYS file using TFTP (Trivial File
Transfer Protocol).
Note: EZWebCon can also be used to reload software.
If a host provides DHCP, BOOTP, or RARP support, it can be used to set the MSS IP address (all methods)
and loadhost information (BOOTP and RARP only).
Some BOOTP and TFTP implementations require a specific directory for the MSS4.SYS file. See your
host’s documentation for instructions.
To manually configure the MSS IP parameters for software reload when running operational software (not
BCP mode), use the following commands.
Figure D-1: Configuring TCP/IP Reload
Note:
For instructions on how to log into the MSS to enter these commands, see the Getting
Started chapter.
The path and filename are case-sensitive and must be enclosed in quotation marks. When attempting to boot
across an IP router, you must configure the router to proxy-ARP for the MSS, or use the bootgateway
feature. For more information, see Bootgateway in the Commands chapter of the MSS Reference Manual
located on the CD-ROM.
MOP
The MSS4.SYS filename is the only parameter that the MSS needs to reload via MOP. Make sure the
service characteristic is enabled on the host's Ethernet circuit, copy the MSS4.SYS file to the MOM$LOAD
directory, and reload the MSS using the Initialize Reload command. Be sure to use binary mode for any
file transfers.
