Configuring Frame Relay 7-21Primary/Secondary Nameidentifies each end of the connection to the console operator. The software does notuse this information.Primary/Secondary DLCIis a logical connection identifier for each end of the PVC.The DLCIs are defined here. If rate control (CIR, B C , BE) will be enforced,be sure to configure those parameters in the frame relay Port record.Primary/Secondary RLPis the RLP at each end of the internal connection.Primary/Secondary Portis the port at each end of the internal connection.Configuring Frame Relay Backup GroupsA Frame Relay Backup Group is one or more DLCIs (on the same RLP) that can actas a backup for one or more "primary" DLCIs (also on the same RLP). If a nodedetects a failure in a primary DLCI connection, the software will search the backupgroup configured for the primary DLCI, and will select the first available DLCI in thatgroup as a backup. The backup will become operational and will remain in that stateuntil the primary becomes active again. If the backup fails while in use, the softwarewill check the status of the primary, then (if necessary) search the primary's backupgroup for another backup.Any sessions in progress when a primary DLCI goes down will not betransferred directly to the backup DLCI, but will be reset, then establishedon the backup.To review existing backup groups, press [A] at the Frame Relay Backup Groups Con-figuration Menu (or [A], [E], [A] from the Main Menu).To configure a backup group, press [B] at the Frame Relay Backup Groups Configu-ration Menu. When prompted, enter a Frame Relay Backup Group Number: 1–255. (Thedefault is 1.)
