Perle Systems 5500208-43 Netmask, Oem-login, Password-limit, Prompt-with-name, Single-telnet

Server Commands

netmask

The network subnet mask. For example, 255.255.0.0.

oem-login

When set, and a custom language file is in use, the login prompt will use the string defined in the language file as the login prompt instead of the default prompt, login:.

password-limit

The number of attempts a user is allowed to enter a password for a serial port connection from the network, before the connection is terminated and the user has to attempt to login again. For users logging into the serial port, if this limit is exceeded, the serial port is disabled for 5 minutes. A user with Admin level rights can restart the serial port, bypassing the timeout, by issuing a kill on the disabled serial port. The default value is 3.

prompt-with-name

Displays the Server Name field value instead of default product name. When enabled, the Server Name is displayed in the IOLAN login prompt, CLI prompt, WebManager login screen, and the heading of the Menu. The default value is Off.

single-telnet

In this mode of operation, the IOLAN will only allow for a single TCP connection at a time to exist for each serial port configured for a reverse connection type. Subsequent connection attempts will be refused until all of the following conditions are met;

zNo active connection to serial port exists and at least 1 second has passed since last connection was terminated.

zAll data from previous connection on the serial port has been transmitted.

The IOLAN has logic to automatically detect when a reverse connection is no longer active. When this happens, the connection is reset and the server can go back to a listening for an incoming connection state.

Applications using Single Telnet need to be aware that there can be some considerable delay between a network disconnection and the port being available for the next connection attempt; this is to allow any data sent on prior connections to be transmitted out of the serial port. Application network retry logic needs to accommodate this feature. The default value is Off.

retry

The number of times the IOLAN will attempt to transfer (using TFTP) a file to/from a host. Enter a value between 0 and 5. The default is 5. A value of 0 (zero) means that the IOLAN will not attempt a retry should TFTP fail.

timeout

The time, in seconds, that the IOLAN will wait for a successful transmit or receipt of TFTP packets before retrying a TFTP transfer. Enter a value between 3 and 10. The default is 3 seconds.

data-logging-buffer-size

The minimum data buffer size for all models is 1 KB. The maximum data buffer size is 2000 KB for DS1/TS1/STS8D, all other models the maximum size is 4000 KB. If the data buffer is filled, incoming serial data will overwrite the oldest data.

Data logging is only valid for Trueport and TCP Sockets profiles.

Values: 1-2000 KB (DS1/TS1/STS8D)

Values: 1-4000 KB (all other models)

Default Buffer Size: 4 KB (DS1/TS1/STS8D)

Default Buffer Size: 256 KB (all other models)
