Filters/Demand Dial

Write security: 2; Read security: 5

The demand dial filters have two purposes: 1) cause the Express XL/XLT in Bridge mode to dial this Connection List profile, and 2) determine which traf- fic will cause the idle timer to be reset, keeping the connection active. The lat- ter is used in Bridge or IP/IPX Router mode. The idle timer is a timer in the Express XL/XLT which continually increments until it reaches the idle time- out parameters value set in the Connection List, at which point the connection is hung-up.

When this filter is enabled, direct control can be placed over which packets are considered as demand and which are ignored. Packets that are ignored cause a connection not to be dialed and do not reset the idle timer of an active con- nection. This is especially helpful for bridged connections since bridges can- not easily distinguish true demand traffic from overhead traffic like certain broadcast and multicast packets. There are three possible selections for this parameter:

Disabled (def) - Turns off demand dial filtering. No packets cause demand dialing for this profile and all outgoing and incoming packets reset the idle timer.

Ignore All - When connected in any mode (Bridge, IP Router, or IPX router), the idle timer is reset only when there is a match in the Filters/Dem Dial Exceptions list. When not connected in Bridge mode only, causes the Express XL/XLT to dial using this Connection List profile if there is a match in the Filters/Dem Dial Exceptions.

Demand All - When connected in any mode (Bridge, IP Router, or IPX router), the idle timer is always reset except when there is a match in the Filters/Dem Dial Exceptions list. When not connected in Bridge mode only, causes the Express XL/XLT to dial using this Connection List profile if there is NOT a match in the Filters/Dem Dial Exceptions list.
