    Remote Access Software Version 5.3 Release Notes

300115-B Rev. A

•

RADIUS Authorization; a user’s authorization information is
supplied by the RADIUS server.

You can use the embedded RADIUS client independently, with the RAC’s
authentication protocol set to RADIUS, or you can use erpcd as a proxy
RADIUS client running under the ACP authentication protocol.

Note that the capabilities provided by the proxy RADIUS client running
under the ACP authentication protocol are a subset of those provided by
the native RADIUS client; any transactions that take place between the
proxy RADIUS client and ACP also take place when the authentication
protocol is RADIUS.

Release 5.1 supports multi-system Multilink PPP (MMP) on platforms
that support PRI connections: RA 6300, RA 5393, 5399 RAC, and
8000 RAC.

MMP is a superset of Multilink PPP, allowing MP links belonging to the
same MP bundle to terminate on multiple RACs. The RACs are combined
together in an MMP group to use all of the incoming channels in the
group, increasing the potential bandwidth of an MP bundle. An MMP
group is a set of one or more RACs that act as a single entity for any MP
links that terminate on any of the RACs in the group; all members of an
MMP group must reside on the same Ethernet segment. MMP groups
usually are organized to correspond to telco hunt groups.

Bay Networks RAs and RACs support MMP for incoming calls only. The
locations of the MP links are completely transparent to remote users;
users need (and receive) no information about which unit terminates a
given MP link. The location of the MP bundle head is determined by the
bundle discovery protocol. Layer 2 Tunneling Protocol (L2TP) tunnels
MP links to remote MP bundle heads, ensuring that successive links on
one unit in an MMP group are combined into the same bundle as the
primary link on another unit.
