Lantronix XPort - Manual (Page 43)

Using Setup Mode for Configuration
Security Settings
You can change security settings via Telnet or serial connections only, not on the
Web-Manager. We recommend that you set security over the dedicated network
or over the serial setup.
If you set parameters over the network (Telnet 9999),
someone else could capture these settings.
Caution: Disabling both Telnet Setup and Port 77FE will prevent users from
accessing the setup menu from the network.
Figure 4-16. Security Settings
Disable SNMP
This setting allows you to disable the SNMP protocol on the unit for security reasons.
SNMP Community Name
This setting allows you to change the SNMP community name. Community name is a
required field for NMS to read or write to a device. The default setting is public. The
name is a string of 1 to 13 characters.
Disable Telnet Setup
Note: If you choose to disable this option, keep in mind that disabling both
Telnet Setup and Port 77FE will prevent users from accessing the setup
menu from the network.
This setting defaults to the N (No) option. The Y (Yes) option disables access to
Setup Mode by Telnet (port 9999). It only allows access locally via the web pages
and the serial port of the unit.
Disable TFTP Firmware Upgrade
This setting defaults to the N (No) option. The Y (Yes) option disables the use of
TFTP to perform network firmware upgrades. With this option, you can download
firmware upgrades over the serial port using DeviceInstaller’s Recover Firmware
procedure. (See
Recovering the Firmware using the Serial Port on 6-2. )
