4-6 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
The Answer profile
IP Options
Internet Protocol (IP) provides connectionless, nonguaranteed transmission of data packets. IP
fragments packets, enabling them to take different paths across the WAN, and then
reassembles them into the proper order at their destination.
The only parameter in the Ethernet > Answer > IP Options subprofile is the Metric parameter.
The Metric parameter specifies the RIP metric (a virtual hop count) of the IP link when the
MAX unit uses RADIUS or TACACS to validate an incoming call, and Use Answer as Default
is enabled. (A hop count indicates how many routers you have to go through to get to the
destination, and a metric is a value that determines how quickly a packet can reach its
destination.) The metric parameter specifies a virtual hop count. Unlike an actual hop count, it
does not include every switched link in the route.
If two routes have the same preference value, the unit chooses the route with the lowest metric.
If you enable Routing Information Protocol (RIP) across the WAN in a Connection profile or
an Answer profile, the hop count for the route can differ from the value of the Metric
parameter in the Route profile because the unit always uses the lower hop count.
IPX Options
The only parameter in Ethernet > Answer > IPX Options is the Peer parameter. The Peer
parameter specifies whether the remote IPX caller is a router or a dialin client. The Answer
profile > IPX Options > Peer parameter specifies how the MAX unit negotiates IPX with
callers that have no configured Connection profile, assuming them to be either IPX routers or
IPX clients. If there is no Connection profile for the caller, the unit needs to treat the caller as a
router (the default) or as a dialin client.
AppleTalk Options
The only parameter in the Ethernet > Answer > AppleTalk Options subprofile is the Peer
parameter. The Peer parameter specifies whether the remote AppleTalk caller is a router or a
dialin client (for a single-user PPP connection). The Peer parameter specifies how the MAX
unit negotiates AppleTalk with callers that have no configured Connection profile, assuming
them to be either AppleTalk routers or AppleTalk clients. If there is no Connection profile for
the caller, the MAX unit needs to treat the caller as a router (the default) or as a dialin client.
TCP-Clear Calls that use a proprietary encapsulation method and rely on raw TCP
sessions to a local host for processing that encapsulation. Raw TCP is
a method of supporting encapsulation performed by an application that
runs on top of TCP. Raw TCP must be understood by both the login
host and the caller. As soon as the connection is authenticated, the
MAX unit establishes a TCP connection to the host.
ARA ARA enables a remote Macintosh workstation to gain access to an IP
network. You can use ARA over a modem or V.120 connection. You
can also use synchronous PPP when the calling unit is an
AppleTalk-enabled MAX unit. A client can dial in using ARA client
software or a PPP dialer that supports AppleTalk.
