Configuring Frame RelayConfiguring Frame Relay SVCs2. The in and out keywords are optional. Configuring the command without the in and out keywords will apply that value to both the incomingand the outgoing traffic values for the SVC setup. For example, frame-relay cir 56000 applies 56000 to both incoming and outgoing trafficvalues for setting up the SVC.You can define multiple map classes. A map class is associated with a static map, not with the interfaceor subinterface itself. Because of the flexibility this association allows, you can define different mapclasses for different destinations.Configuring a Map Group with E.164 or X.121 AddressesAfter you have defined a map group for an interface, you can associate the map group with a specificsource and destination address to be used. You can specify E.164 addresses or X.121 addresses for thesource and destination. To specify the map group to be associated with a specific interface, use thefollowing command in global configuration mode:CommandRouter(config)# map-list map-group-name source-addr {e164 | x121}source-address dest-addr {e164 | x121} destination-addressPurposeSpecifies the map group associated withspecific source and destination addresses forthe SVC.Associating the Map Class with Static Protocol Address MapsTo define the protocol addresses under a map-list command and associate each protocol address with aspecified map class, use the class command. Use this command for each protocol address to beassociated with a map class. To associate a map class with a protocol address, use the followingcommand in map list configuration mode:CommandRouter(config-map-list)# protocol protocol-address classclass-name [ietf] [broadcast [trigger]]PurposeSpecifies a destination protocol address and a FrameRelay map class name from which to derive QoSinformation.The ietf keyword specifies RFC 1490 encapsulation; the broadcast keyword specifies that broadcastsmust be carried. The trigger keyword, which can be configured only if broadcast is also configured,enables a broadcast packet to trigger an SVC. If an SVC already exists that uses this map class, the SVCwill carry the broadcast.Configuring LAPF ParametersFrame Relay Link Access Procedure for Frame Relay (LAPF) commands are used to tune Layer 2 systemparameters to work well with the Frame Relay switch. Normally, you do not need to change the defaultsettings. However, if the Frame Relay network indicates that it does not support the Frame Reject frame(FRMR) at the LAPF Frame Reject procedure, use the following command in interface configurationmode:11
