Configuring Frame Relay Ports5-11Frame Relay Status and ConfigurationPriorityThe Outgoing DLCI Priority value allows you to assign relative priority levels tothe DLCIs configured on the selected physical port. The allowable range is 0-4,with 0 being the lowest priority.Backup Group NumberUse this field to specify whether this DLCI is a primary or a backup DLCI. If it is aprimary DLCI, enter the number (1-255) that identifies the Frame Relay BackupGroup that will take over if this DLCI fails. If it is a backup DLCI, enter 0. A DLCIcannot be both a backup and a primary DLCI.This parameter is applicable only on an initiating node, which is the node thatwill initiate the switchover to a backup DLCI. At switchover, the initiating nodenotifies the remote (non-initiating) node of the change. Do not configure a BackupGroup Number on this DLCI at the remote (non-initiating) end.Backup ProtocolThis field is only configurable if the Backup Group Number is set to 0, indicatingthat the DLCI being configured is a backup DLCI. Set this field to Enabled if thisDLCI will be used as a remote (non-initiating) backup. The DLCI will wait for abackup protocol message from the initiating end, telling the backup where tosend the rest of the messages. Set this field to Disabled if this DLCI is an initiatingbackup.StateAlthough it appears to be a settable parameter, the value displayed in the Statefield simply indicates the internal status of the entry you are configuring: active,inactive, or invalid. The value displayed here indicates only the device’s efforts toadd the entry to its MIB table.Changing DLCI Rate ValuesTo edit the rate values assigned to each configured DLCI:1. If you wish to modify an existing entry, be sure that entry is highlighted in thelist box portion of the window.2. Enter and/or edit the values displayed in the text boxes, as desired.(Remember, some values which are settable from this window must mirrorvalues received from your service provider or configured elsewhere; be surethese values match as necessary.)NOTEIf you are configuring a primary DLCI, you must set this value to 0 until you haveconfigured a Frame Relay Backup Group (see Configuring a Frame Relay Backup Group,page 5-13). Then, re-access the Frame Relay DLCI Table and specify the desired backupgroup.
