Filters/Demand Dial
Write security: 2; Read security: 5
The demand dial filters have two purposes: 1) cause the Express L128/L128T in Bridge mode to dial this Connection List profile, and 2) determine which traffic will cause the idle timer to be reset, keeping the connection active. The latter is used in Bridge or IP/IPX Router mode. The idle timer is a timer in the Express L128/L128T which continually increments until it reaches the idle
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 L128/L128T 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 L128/L128T to dial using this Connection List profile if there is NOT a match in the Filters/Dem Dial Exceptions list.
