Chapter 5 Device Network Settings Table 31 Device Operation > Device Configuration > Network > WAN Backup > Advanced (Prestige) (continued) LABEL DESCRIPTION Multicast Version Select IGMP-v1 or IGMP-v2. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about inter operability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. PPP Options PPP Encapsulation Select CISCO PPP from the drop-down list box if your backup WAN device uses Cisco PPP encapsulation; otherwise select Standard PPP. Enable Compression Select this check box to enable stac compression. Connection Nailed-Up Connection Select Nailed-Up Connection when you want your connection up all the time. The device will try to bring up the connection automatically if it is disconnected. Connect on Demand Select Connect on Demand when you don't want the connection up all the time and specify an idle time-out in the Max Idle Timeout field. Max Idle Timeout Specify an idle time-out in the Max Idle Timeout field when you select Connect on Demand. The default setting is 0, which means the Internet session will not timeout. Budget The configuration in the Budget fields has priority over your Connection settings. Allocated Budget Type the amount of time (in minutes) that the dial backup connection can be used during the time configured in the Period field. Set an amount that is less than the time period configured in the Period field. If you set the Allocated Budget to 0, you will not be able to use the dial backup connection. Period Type the time period (in hours) for how often the budget should be reset. For example, to allow calls to this remote node for a maximum of 10 minutes every hour, set the Allocated Budget to 10 (minutes) and the Period to 1 (hour). If you set the Period to 0, there is no budget control and the device uses the Connection settings. Back Click this to return to the previous screen. Apply Click this to save the changes.
