PVC connections are configured.

 

No Port-1, PVC connection, or management DLCI is

 

configured.

 

T

Disable

No frame relay discovery or automatic configuration

 

takes place.

 

The FrameSaver unit will be configured manually.

 

 

NOTE:

If the default setting (1MPort or 1PPort) is not the setting required for your application, change the Frame Relay Discovery Mode before connecting the network cable or editing discovered option settings. Otherwise, the FrameSaver unit will start discovering DLCIs as soon as it powers up.

If this occurs, you can recover by deleting the discovered DLCIs. If only a local management PVC between the router and the FrameSaver unit has been configured, simply select the desired Frame Relay Discovery Mode and Save the change.

The default discovery mode, depending on model, is 1MPort or 1PPort.

When 1MPort mode is active, the unit creates for each DLCI discovered on the network a multiplexed network interface DLCI (which contains two EDLCIs: one for Port-1 data and the other for management), a standard Port-1 DLCI (with the same number as the network interface DLCI), and a Management PVC, then cross-connects them. When LMI is active on the network interface and PVC status information (with provisioned DLCI numbers) is next received from the network, the unit automatically saves the settings to the Current Configuration area.

When 1PPort mode is active, the unit uses the Network DLCI values obtained from the Network LMI status response message to automatically configure for each DLCI a corresponding DLCI for Port 1 having the same numeric value as the Network DLCI, and automatically cross connects them. The DLCIs created on the network side are IP Enabled (not standard or multiplexed) DLCIs. In addition, payload management is configured for the network DLCI and assigned the Node IP Address.

Configuration options set by selecting a discovery mode can be manually modified, refined, or deleted at any time using the Configuration menus. No previously discovered and configured DLCIs or cross-connections will be removed unless authorized or Automatic Circuit Removal is enabled (see Automatically Removing a Circuit on page 4-11). Additional discovered DLCIs will be configured according to the current Frame Relay Discovery Mode setting. Selecting or changing the setting will not affect IP Addresses or Subnet Masks.

NOTE:

When auto-configuration creates a multiplexed DLCI, but a standard DLCI is needed, change the DLCI to standard from the network DLCI Records screen: Configuration NetworkDLCI Records
