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.

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

 

on page 89 for more 

information about bandwidth management features such as 
dial-on-demand.

Table 11   Port and Path Options

Multiple paths per 
port: dynamic paths

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.

Multiple paths per 
port: static paths

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.

Multiple ports per 
path: virtual ports

A virtual port can be assigned to a path or to a SysCallerID 
that represents a remote site.
