The following are new features in this release:

RAS 1500 includes support for local, Remote Authentication Dial In User

Services (RADIUS) and NT NOS authentication. In addition to Password

Authentication Protocol (PAP) and Challenge Handshake Authentication

Protocol (CHAP) support, Release 2.5 adds MSCHAP Versions 1 and 2 for

local and RADIUS authentication. Versions 1 and 2 are separate protocols

and are incompatible with each other. Therefore, you must set Point To

Point (PPP) Receive Authentication using either Version 1 or Version 2 of

MSCHAP.

You may set PPP Receive Authentication through the Web Configuration

Interface. From the main, browser-based Web Configuration Interface

page, click Authentication under the Administration menu. The

selections for MSCHAPV1 or MSCHAPV2 are under the PPP

Authentication Type pulldown menu.

You may also set PPP Receive Authentication through the Command Line

Interface (CLI). The CLI command to set PPP Receive Authentication using

either Version 1 or Version 2 is as follows:

SET PPP RECEIVE_AUTHENTICATION [ANY CHAP MSCHAPV1 MSCHAPV2

NONE PAP]

Note the use of "any" in the above CLI command example. If you

previously set any scripts using "either" (which was specified in the CLI

command for Version 2.0), you will need to change "either" to "any" in

the script.

Ethernet now has full duplex functionality. Full duplex is typically

implemented between two endpoints. Both endpoints of the full duplex

link must operate in full duplex mode in order for full duplex to be fully

operational. If both endpoints are not set for full duplex functionality,

performance may degrade. The CLI command to set full duplex or half is

as follows:

SET ETHERNET DUPLEX_MODE [FULL_DUPLEX HALF_DUPLEX]

Auto-negotiation is not supported on the Ethernet port. Therefore, when

you set full duplex while connected through a switch on the Ethernet

port, make sure you manually set the switch to full duplex mode.
