Configuring Frame Relay 7-151 If rate control will not be used, configure the Committed Information Rate (CIR) tomatch the line speed on the port. Otherwise, the DE-bit will be set on all received frames.2 CIR = Committed Information Rate. (See first parameter in table.)3 Applicable only on the initiating node. (See explanation.) If configuring a DLCI that willbe backed up, you must leave this value at 0 until you have configured a backup group.Then re-enter Port Configuration on this RLP/port/DLCI and specify the desired group.A value of 0 means that the DLCI will not be backed up; therefore, set the Group to 0 ifthe DLCI will be a backup.4 Set to N for the initiating backup DLCI and Y for the remote backup DLCI.5 Displayed only if Backup Group Number is a value other than 0.6 If set to 65535, switchback will not occur unless the backup fails.Port Typespecifies the protocol the port will support. Selecting this parameter will display a listof valid protocols. (Protocol configuration is described in Chapter 5.)Physical Port Interfaceis determined by the Line Interface Card(s) and attached cables. The RLP record iden-tifies the LIC, and only the valid interfaces will be displayed on the Port screen,among: RS-232, V.35, RS-449, and X.21 . (RS-449 and X.21 i nterfaces are valid if the LICis RS-422.)Blocked Port Flagwill cause the port to be enabled (N) or disabled (Y) at node IPL. The port will remainin that state until this parameter is changed or an on-line enable ([B], [B], [C] from theMain Menu) or disable ([B], [B], [A] from the Main Menu) is performed.If set to Y, no backup DLCIs on this port will be used (even if the port is enabled viaon-line port enable).Table 7-4 Frame Relay DLCI ParametersParameter Valid Values Default ValueCommitted Information Rate (In/Out) 0–2000 (Kbits/sec) 1 0 1Committed Burst Size (In/Out) .08 CIR–16xCIR (in kbits) 2 CIRExcess Burst Size (In/Out) 0–{BC /CIR x (linespeed minusCIR)} 1 0BECN Recovery Count 1–255 (packets) 8Outgoing DLCI Pr iority 0–4 0Backup Group Num ber 3 0–255 0Enable Backup Protocol?
