X.25 Configuration 7-17
Configuring the WAN Call Directory
The WAN Call Directory is a list of WAN Call Destination configurations
you want to use for each virtual circuit. You must create at least one WAN
Call Destination configuration for each desired destination. WAN Call
Destination configurations contain parameters to be applied by Emulex X.25
software when establishing and maintaining calls to the destination.
Two basic types of call configurations are possible: permanent and on-
demand. If the connection fails, attempts to reconnect are tried at periodic
intervals. This type of connection is suited for use with dynamic routing
protocols like RIP or NetWare Link Services Protocol (NLSP) software.
On-demand calls specify that the connection should be established only when
needed. Maintenance data such as routing updates is suppressed. These types
of connections are terminated whenever the link is void of network data
longer than the configured Idle Line Time-out value. A connection failure is
retried only when more network data is directed to the remote destination.
To configure WAN Call Destinations for X.25 interfaces, perform the
following steps:
1) From the Internetworking Configuration menu, select WAN Call
Directory , and press <Enter>
