Use the Connections web page to connect external devices and outbound network connections (such as Telnet or SSH) in various configurations.
An SLC device port attached to an external device can be connected to one of the following endpoints:
Another device port attached to an external device
Another device port with a modem attached
An outgoing Telnet or SSH session
An outgoing TCP or UDP network connection
This enables the user to set up connections such as those described in Typical Setup Scenarios. You can establish a connection at various times:
Immediately: These connections are always re-established after reboot.
At a specified date and time: These connections connect if the date and time have already passed.
After a specified amount of data or a specified sequence of data passes through the connection. Following reboot, the connection is not reestablished until the specified data passes through the connection.
To configure a device port’s connection:
1. Complete the following fields:
Port |
The number of the device port you are connecting. This device port must be connected to an external serial device and must not have command line interface logins enabled, be connected to a modem, or be running a loopback test. Note: To see the current settings for this device port, click the Settings link. |
Data Flow |
Select the arrow showing the direction (bidirectional or unidirectional) the data will flow in relationship to the device port you are connecting. |
to |
From the drop-down list, select a destination for the connection: a device port connected to a serial device, a device port connected to a modem, or an outbound network connection (Telnet, SSH, TCP Port, or UDP Port). Note: To see the current settings for a selected device port, click the Settings link. |
IP Address |
The IP Address of the destination. This entry is required if the to field is set to Telnet out, SSH out, TCP port, or UDP port. |
Port |
If the to field is set to Device Port or Modem on Device Port, enter the number of the device port. For all other options, this is the TCP/UDP port number, which is optional for Telnet out and SSH out, but required for TCP Port and UDP Port. Note: If you select Device Port, it must not have command line interface logins enabled or be running a loopback test. |
SSH Out Options |
Select one of the following optional flags to use for the SSH connection: User: Login
ID to use for authenticating on the remote host. |
Trigger |
Select the condition that will trigger a connection. Options include: Connect now: Connects immediately, or if you reboot the SLC, immediately on reboot. Connect at date/time: Connects at a specified date and time. Use the drop-down lists to complete the date and time. Upon rebooting, the SLC reestablishes the connection if the date/time has passed. Auto-connect on characters transferring: Select the arrow indicating the direction of the data transfer and either the minimum number of characters or a specific character sequence that will trigger the connection. You can select the direction of the data transfer only if Data Flow is bidirectional. Upon rebooting, the SLC does not reestablish the connection until the specified data has passed through one of the endpoints of the connection. |
To save, click Apply.
To view, update, or disconnect a current connection:
The bottom of the Connections web page displays current connections.
To disconnect (delete) a connection, select the connection in the Select column and click the Terminate button.
To reestablish the connection, create the connection again in the top part of the page.
