Serial Line Internet Protocol (SLIP)
To use the SLIP link for booting and/or dumping, set the following parameters:
Using SLIP for Booting/Dumping
• The slip_load_dump_host parameter defines the IP address from which the Model 5390
server requests boots and to which the Model 5390 server dumps. This parameter can match
the IP address specified in the remote_address parameter. You must set
slip_load_dump_host when using a SLIP link for downloading software.
Use slip_load_dump_host in place of the Model 5390 parameter pref_load_host if the port
is defined with the Model 5390 parameter load_dump_sequence.
Set the Model 5390 parameter load_dump_sequence to define the port number(s) over which
a boot or dump is to occur. The default is net for the local network, such as Ethernet. Enter a
SLIP link as asynn, where nn is the port number. For example, if you want a boot request to
try the SLIP link on port 2 first, then the SLIP link on port 6, and finally the local network, enter:
command: set annex load_dump_sequence asy2,asy16,net
You can select up to four interfaces. The preference of the boot
and/or dump request would be performed in the order you specified. Each interface must be
separated by a comma.
• The preferred load host is defined by the network interface through which the Model 5390
server is booting. Use pref_load_host with the local network interface; use
slip_load_dump_host with individual SLIP links.
• The slip_allow_dump parameter disables using the SLIP link for dumps. If you include this
port in the load-dump sequence list, the Model 5390 server automatically dumps to the host
specified in the slip_load_dump_host parameter.
On a 9600 baud line, a dump of a one MB Model 5390 server can take about ten minutes.
To download the operational code, but prevent dumps:
Downloading Operational Code without Dumping
• Specify the port using the load_dump_sequence parameter.
• Specify the IP address of the preferred load host using the slip_load_dump_host parameter.
• Set the slip_allow_dump parameter to N.
