ONFIGURATION OF ORTS
A path that is assigned at system initialization time to a port is a static
path. A path that is assigned to a port when a dial call is placed is a
dynamic path.
Multiple paths can be assigned to a port and multiple ports can be
assigned to a path as 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 MLP 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
To configure multiple ports over one path, you create virtual ports. A
virtual port can be assigned to a static path, or for PPP as using in a virtual
private network (VPN), it can be assigned to the SysCallerID of a remote
site. SysCallerID virtual ports use paths in a dial pool and are not
associated to any one path.
A virtual port functions the same way as a nonvirtual port does, that is, as
a logical interface that represents a connection to a network.

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 a path for disaster recovery, 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.
