set config
Chapter 2 Command Descriptions 99
optimize={latency|throughput}
Configures how the Digi device handles network latency.
latency
Choose latency if the Digi device will handle delay-sensitive data.
throughput
Choose throughput if overall network throughput is more important
than latency. For Digi One IAP, the default is "latency." For all other
models, the default is "throughput."
ping-arp={on|off}
Enables or disables the ping-arp protocol to set the IP address.
rarp={on|off}
Enables or disables the RARP protocol to set the IP address.
realport=tcp port
The TCP port number used for RealPort connections. The default is 771.
redirect={listen|ignore}
Specifies how routing redirect messages should be handled.
listen
Accept ICMP routing redirect messages. Use this option only if you
have not configured the device server to forward RIP packets.
ignore
Discard ICMP routing redirect messages
The default is “ignore.”
rpkeepalives={on|off}
Enables or disables sending of RealPort keep-alives. RealPort keep-
alives are messages inside the RealPort protocol, sent approximately
every 10 seconds, to tell whoever is connected that the connection is still
alive. RealPort keep-alives are different from TCP keep-alives, which are
done at the TCP layer, and configurable.
As RealPort keep-alives generate additional traffic--several bytes every
10 seconds--this option allows you to turn them off. In situations such as
cellular/mobile wireless communications, when you are paying by the
byte, such additional traffic is undesirable when a TCP keep-alive can do
the same job, and only when the connection is idle.
If you want to have the RealPort keep-alive set to “off;” consider using a
TCP keep-alive instead. This is because if the link is not closed properly,
you could end up with your port being “locked up” with a dead TCP
session, which is why RealPort keep-alives were implemented in the first
place.
save={on|off}
Specifies whether configuration changes are saved. On saves
configuration changes to flash memory. Off means that changes will be
discarded when the device server is reset. The default is "on."
