Resetting Ports
The Digi CM allows you to restart all processes associated with a port and to
disconnect all sessions.
To reset an individual port:
1. Click Serial port > Configuration > Port number.
2. Click Reset this port: Reset.
Reset individual port settings
Individual ports can be reverted to factory defaults.
1. Click Serial port > Configuration > Port number.
2. Click Set this port as factory default: Set.
Port Title
The Digi CM offers multiple ways to configure the port title; both manually and
automatically. The default is set to “Port Title # xx” with xx being the port-
number.
Automatic Device Recognition allows the Digi CM to evaluate the attached
devices and populate the port title. Additionally the Digi CM can generate a
SNMP trap or send an e-mail in case the response of the device changes or it
stops responding.
If Active detect is selected, a configurable probe string (carriage return =0x0d
by default) is sent to the console port and the response is saved to a file at
/var/run/systemrep_raw.portxx with xx being the port number.
This file is parsed using a script /tmp/cnf/active_detect and the operating
system and device name are written to files: /var/run/HostnamePortxx and
/var/run/OSPortxx.
The commands to parse the system response are user customizable, so if you
have a device that is not recognized immediately by the Digi CM, he can add a
rule to the file.
If Passive detect is selected, no probe string is sent to the attached device but
the port buffer is analyzed.
The script /tmp/cnf/passive_detect is executed and the results are saved to
files: /var/run/HostnamePortxx and /var/run/OSPortxx.
After editing the scripts as either active_detect or passive_detect, save them to
flash using the saveconf command so they are not lost after a reboot.
