4-30 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
The Connection profile
Encaps=ARA
When Connections > Connection profile > Encaps=ARA, the following parameters appear in
the interface for Ethernet > Connections > Connection profile > Encaps Options:
IP Options
The Ethernet > Connections > Connection profile > IP Options subprofile includes the
following parameters that define IP addresses for the remote-end host, for the link’s remote
interface to the WAN, and for the MAX unit:
Distance parameters
The following parameters in Ethernet > Connections > Connection profile > IP Options define
how quickly a packet reaches its destination, the shortest route to the destination, whether to
keep the route private, and the values for preference and metric when the WAN is down:
Parameter Specifies
Password Password that an incoming ARA caller must supply (in a Connection
profile) or the password the foreign agent must specify under Ascend
Tunnel Management Protocol (ATMP) in order to access this unit (in
an Ethernet profile).
Max Time (min) Maximum connect time in minutes for the ARA dial-in. The MAX
unit initiates an ARA disconnect when the specified time is up. The
ARA link goes down cleanly, but remote users are not notified. Users
find out the ARA link is gone only when they try to access a device.
Parameter Specifies
LAN Adrs IP address of remote-end host or route.
WAN Alias IP address of the link’s remote interface to the WAN. It is used to
identify a numbered interface at the remote end of the link.
IF Adrs Numbered interface IP address for the MAX unit. Interface-based
routing allows the unit to operate like a multihomed Internet host. In
addition to the system-wide IP configuration, the unit and the far end
of the link have link-specific IP addresses. The unit address for this
connection is specified in the IF Adrs parameter. The far-end
numbered interface address is specified in the WAN Alias parameter.
Parameter Specifies
Metric RIP metric (a virtual hop count) associated with the IP route. A metric
is a value that determines how quickly a packet can reach its
destination. The value you enter is a number between 1 and 15. The
default setting is 7. The higher the number you specify, the less likely
that the unit brings the link or route online.
