Netmask: Number of Bits for Host Part

A netmask defines the number of bits taken from the IP address that are assigned for the host part.

Netmask: Number of Bits for Host Part (0=default) (0) _

Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits

The unit prompts for the number of host bits to be entered, then calculates the netmask, which appears in standard decimal-dot notation (for example, 255.255.255.0) when the saved parameters display.

Change Telnet Configuration Password

Setting the Telnet configuration password prevents unauthorized access to Setup Mode through a Telnet connection to port 9999 or through web pages. The password must have 4 characters.

Change telnet config password (N) ? _

An enhanced password setting (for Telnet access only) of 16 characters is available under Security Settings (Option 6) on page 89.

Note: You do not need a password to access the Setup Mode window by a serial connection.

Change DHCP Device Name:

Change the DHCP name if the network is DHCP-enabled.

Change DHCP device name (not set) ? (N) N

Enter new DHCP device name :

WLAN Configuration (Option 4)

Without adequate protection, a wireless LAN is susceptible to access by unauthorized users. For that reason, XPress DR+W features the WPA security standard, based on IEEE802.11i. WEP is provided for backwards compatibility and interaction with older devices.

Note: Due to regulations, the country-specific setting has been removed from the setup menu and Web Manager. We provide a separate utility for changing the Country/Zone setting. The utility is called SetZone and is included in the XPress DR+W package. It is also available for download from the Lantronix web site.

The syntax is SetZone <IP address> [<zone abbreviation>]
