Updating Software Reloading MSS Software
D - 5
D.2.2 TCP/IP
Downloading involves the Trivial File Transfer Protocol (TFTP), and
optionally BOOTP. The MSS will make a BOOTP query each time it boots. If a
host provides BOOTP support, it can be used to set the ServerÕs IP address
and loadhost information. Add the ServerÕs name, IP address, hardware
address, download path, and loadÞle name to the BOOTP Þle (usually /usr/
etc/bootptab). The path and Þlename are case sensitive; they must be
enclosed in quotation marks (ÒÒ).
Some BOOTP and TFTP implementations require a speciÞc directory for the
MSS.SYS Þle. In this case, the path should not be speciÞed in the bootptab
ÞleÑthe Þle must be placed in the bootptab directory. If BOOTP cannot be
used to conÞgure the ServerÕs IP parameters, conÞgure them by hand using
the following commands:

NOTE: Before the MSS can be booted across an IP router, the router
must be configured to perform proxy arping for the MSS.
D.2.3 MOP
Copy the MSS.SYS Þle to the MOM$LOAD directory. The MSS.SYS Þlename
is the only parameter that the MSS needs to reload via MOP. Make sure the
service characteristic is enabled on the hostÕs Ethernet circuit, then reload the
server using the following command:
