Port Alert Settings
The Port Alert Settings dialog box provides a way for you to be informed about
events that occur on the devices connected to the CN8000's ports.
You can specify up to 10 types of events (e.g., Power On) in the Alert String
fields. When a specified alert occurs during the serial console session, the
CN8000 writes the event information to the log file.

In case the CN8000 cannot be accessed with the usual LAN-based methods, it
can be accessed with an external modem via the switch’s RS-232 port. To
enable support for PPP (modem) operation, click to put a checkmark in the
Enable Out of Band Access checkbox.
Note: 1. Enabling out of band access automatically enables Dial In operation.
See PPP Modem Operation, page 172, for set up and operation
details.
2. For the modem session, the CN8000 has an IP address of
192.168.192.1; the user side has an IP address of 192.168.192.101.
When you enable out of band access, the Enable Dial Back, and Enable Dial
Out functions become available, as described in the sections that follow.
Enable Dial Back
As an added security feature, if this function is enabled, the switch disconnects
the connections that dial in to it, and dials back to one of the entries described
in the table below:
Item Action
Enable Fixed
Number Dial Back
If Fixed Number Dial Back is enabled, when there is an
incoming call, the CN8000 hangs up the modem and dials back
to the modem whose phone number is specified in the Phone
Number field.
Key the phone number of the modem that you want the
CN8000 to dial back to in the Phone Number field.
