Dynamic Paths

C P
ONFIGURATION OF ORTS AND
A port is the logical interface used by the software to represent a
connection to a network.
By default, each path is assigned to one port. For example, all network
traffic received on physical path 1 is treated by the software as arriving on
logical port 1, and all traffic that the software transmits through logical
port 1 passes through physical path 1.
A path that is assigned to one port is a static path. Some configurations
require the options described in Table 11.
Table 11 Port and Path Options
Option
Multiple paths per
port: dynamic paths
Multiple paths per
port: static paths
Multiple ports per
path: virtual ports
Ports running PPP can use a dial pool of available paths. A dial pool
enables you to dial multiple destinations, use bandwidth-on-demand,
and failover to another line without having to reserve specific paths for a
port. A dial pool is created when you unbind a path from its port by
using:
SETDefault !<path> -PATH DialCONTrol = DYNamic
See "Configuring Bandwidth Management for PPP" on page 89 for more
information about bandwidth management features such as
dial-on-demand.

Description
A dynamic path is not assigned to any one port, but is
available in a dial pool. A dial pool enables you to dial
multiple destinations, use bandwidth-on-demand, and
failover to another line without having to reserve specific
paths for a port. A port may require multiple paths from the
dial pool.
Use multiple static paths on the same port:
To use both B channels together on a built-in ISDN
connector using Multilink PPP.
To reserve a path for disaster recovery.
To use a path for dial-on-demand, failover, or
bandwidth-on-demand.
A virtual port can be assigned to a path or to a SysCallerID
that represents a remote site.
