Configuring Frame Relay 6-33Frame Relay PVC Parameters1 The DLCI must match the DLCI configured at the remote end of the physical link.2 Some formulae that might help in determining these values are:BC >= 8 times maximum packet size.BE <= BC multiplied by [(line speed/CIR) minus 1].Connection Priorityprioritizes this connection for intra-nodal traffic; the higher the number, the higher thepriority. (This priority has no effect on traffic exiting a node.)A priority is also configured in Node Defaults, as well as for each logical port, SNAPU, LLC2 host, Bridge Port/LLC2 Interface, IP interface, IPX interface, and SVCsubscriber. The device processor in the node uses these priorities to help determine theorder in which it will process protocols.When configuring priorities, be careful to consider the types oftraffic being routed on other connections in the node.Primary/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.Primary/Secondary LPis the (FRX6000 only) RLP at each end of the internal connection.Primary/Secondary Portis the port at each end of the internal connection.Table 6-7 Frame Relay PVC ParametersParameter Valid Values Default ValueConnection Priority 0–9 0Primary/Secondary Name 0–31 characters nonePrimary/Secondary DLCI 16–991 1 16Primary/Secondary LP FRX4000, FRM: 0FRX6000: 0–7 0Primary/Secondary Port 0–7 0Committed Inf.
