Chapter 2 Command Descriptions 33
reset status
These PPP status values describe why a PPP link was terminated.
idle resets
The number of resets because the idle timeout was reached/exceeded
for transmitted and received data. These idle timeouts are set by the
“set pppoutbound” command. Most of the time, no idle timeout is used
on transmitted data.
no carrier resets
The number resets because the carrier was dropped for any reason.
no service resets
The number of resets because the data network was not available.
Note: For Digi Cellular Family products, “no carrier” and “no service” resets indicate
problems with your cellular service. “No service” resets could be cased by low
signal strength. Review the signal strength and reposition the antenna or Digi
device as needed. An external high-gain or directional antenna may be
needed. These resets can also be due to roaming issue. To check the signal
strength and current carrier settings, issue a “display mobile” command.
admin resets
The number of resets done for administrative purposes, such as
issuing “kill” commands, or disconnecting a PPP session in the Web
user interface’s Connections page by clicking the Disconnect button.
non-admin resets
The number of LCP termination requests made from the network; that
is, the network notifies the Digi device that the PPP link is being
brought down.
surelink resets
The number of resets caused by SureLink bringing down the PPP link
and reestablishing it. SureLink performs three tests to monitor the
integrity of the PPP link: ping, DNS, and TCP connection testing. The
“set surelink” command has options for setting how these tests are
performed. (see "set surelink" on page 202). If SureLink is unable to
complete these tests, it concludes that the link is broken, and
reestablishes the connection.
lcp keepalive resets
The number of resets caused by the LCP keepalive tests. LCP
keepalive tests are similar to the SureLink link integrity monitoring
tests, and perform the equivalent of a ping test for the PPP link. If the
cellular network does not ping back after the number of replies
specified by the number of consecutive missed replaces on the
“set pppoutbound” command option “lcp_ka_max_missed_replies,”
the LCP keepalive feature drops the link.
