Data Settings

Note:

Check the serial device’s equipment settings and documentation for the proper

settings. The device port and the attached serial device must have the same settings.

Authentication

If selected, the SLB requires user authentication before granting access to the

port.

Authenticate

is selected by default for

Telnet

in and

SSH in

, but not for

TCP in

.

Timeout

To cause an idle Telnet, SSH or TCP connection to disconnect after a specified

number of seconds, select the checkbox and enter a value from 1 to 1800

seconds. The default is no timeout.

Seconds

Number of seconds before a timeout.

IP Address

IP address used for this device port so a user can Telnet, SSH, or establish a raw

TCP connection to this address and connect directly to the device port.

For Telnet and SSH, the default TCP port numbers (22 and 23, respectively) are

used to connect to the device port. For raw TCP, the TCP port number defined

for

TCP In

to the device port is used.

Web SSH/Telnet

Columns

Number of columns in the Web SSH/Telnet applet when this device port is

accessed via the applet.

Rows

Number of rows in the Web SSH/Telnet applet when this device port is accessed

via the applet.

Baud

The speed with which the device port exchanges data with the attached serial

device.

From the drop-down list, select the baud rate. Most devices use 9600 for the

administration port, so the device port defaults to this value. Check the equipment

settings and documentation for the proper baud rate.

Data Bits

Number of data bits used to transmit a character. From the drop-down list, select

the number of data bits. The default is

8

data bits.

Stop Bits

The number of stop bit(s) used to indicate that a byte of data has been transmitted.

From the drop-down list, select the number of stop bits. The default is

1

.

Parity

Parity checking is a rudimentary method of detecting simple, single-bit errors.

From the drop-down list, select the parity. The default is

none

.

Flow Control

A method of preventing buffer overflow and loss of data. The available methods

include none, xon/xoff (software), and RTS/CTS (hardware). The default is

none

.

Enable Logins

For serial devices connected to the device port, displays a login prompt and

authenticates users. Successfully authenticated users are logged into the

command line interface.

The default is disabled.

This is the correct setting if the device port is the endpoint

for a network connection.

Max Direct Connects

Enter the maximum number (1-10) of simultaneous connections for the device

port. The default is 1.
