2.5
New Features
The following are new features in this release:
MSCHAP Version 1
and
MSCHAP Version 2
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.
Full Duplex Ethernet
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.
