Data Switch Connection
Use the data switch connection to provide the flexibility of using more than one
management station to communicate with more than one probe.
To make a data switch connection to the probe, connect a NetMetrix management
station to the probe’s RS-232C port through a data switch. Set the Serial Port
Mode to Direct, if your probe is directly connected to the data switch, or set it to
Modem, if your probe must dial through a modem to another modem that is
attached to the data switch.
To allow traps to be sent from the probe to your management station, specify a
Serial Trap Destination of type Switch or Modem Switch, using NetMetrix.
Refer to your data switch documentation for information on setting up your data
switch. There are many variations available for this connection method. Figure 3-
14 on page 67 shows a possible data switch connection scheme.
