This chapter describes the function and displays the syntax of each SNA Frame Relay access support command. For more information about defaults and usage guidelines, see the corresponding chapter of the Bridging and IBM Networking Command Reference.
frame-relay map llc2 dlci-number
Use the frame-relay map llc2 interface configuration command to map LLC2 traffic to a DLCI.
| dlci-number | Frame Relay data link connection identifier. |
frame-relay map rsrb dlci-number
Use the frame-relay map rsrb interface configuration command to specify the DLCI number onto which the RSRB traffic is to be mapped.
| dlci-number | Frame Relay data link connection identifier. |
[no] fras ban local-ring bridge-number ring-group ban-dlci-mac dlci dlci#1 [dlci#2 . . .dlci#5]
[bni mac-addr]
Use the fras ban interface configuration command to associate bridging over a Frame Relay network using boundary access node (BAN). Use the no form of this command to cancel each association.
| local-ring | Decimal number from 1 to 4095 describing the Token Ring interface. |
| bridge-number | Decimal number from 1 to 15 that uniquely identifies a bridge connecting two rings. |
| ring-group | Decimal number from 1 to 4095 representing a collection of Token Ring interfaces on one or more routers. |
| ban-dlci-mac | Frame Relay BAN PVC MAC address. |
| dlci#1 [dlci#2 . . .dlci#5] | Frame Relay data link connection identifier. Each DLCI number is unique and is a decimal within the range of 16 to 1007. The keyword dlci precedes the list of one or more DLCI numbers. If more than one DLCI number is needed for load balancing in the FRAS BAN configuration command, a maximum of five DLCI numbers are allowed. |
| bni mac-addr | (Optional) Boundary node identifier (BNI) MAC address of the NCP that receives frames from the router. |
[no] fras map llc mac-address lan-lsap lan-rsap serial port frame-relay dlci fr-lsap fr-rsap
[pfid2 | afid2 | fid4]
Use the fras map llc interface configuration command to associate an LLC connection with a Frame Relay connection. Use the no form of this command to cancel the association.
| mac-address | MAC address of the downstream SNA device. It is a 48-bit dotted-triple address. |
| lan-lsap | Local SAP address of the downstream SNA device in hexadecimal. For SNA, the address must be multiples of 4. |
| lan-rsap | Destination SAP address from the perspective of the downstream SNA device in hexadecimal. For SNA, the address must be multiples of 4. |
| serial port | Serial interface on which Frame Relay is configured. |
| frame-relay dlci | Frame Relay data link connection identifier. |
| fr-lsap | Local SAP address of the logical link connection on the CFRAD. |
| fr-rsap | Destination SAP address on the host. |
| pfid2 | (Optional) FID2 SNA transmission header for SNA peripheral traffic. |
| afid2 | (Optional) FID2 transmission header for APPN traffic. |
| fid4 | (Optional) Transmission header used on SNA subarea flows. |
[no] fras map sdlc sdlc-address serial port frame-relay dlci fr-lsap fr-rsap [pfid2 | afid2 | fid4]
Use the fras map sdlc interface configuration command to associate an SDLC link with a Frame Relay DLCI. Use the no form of this command to cancel the association.
| sdlc-address | SDLC address of the downstream SNA device in hexadecimal. |
| serial port | Serial interface on which Frame Relay is configured. |
| frame-relay dlci | Frame Relay data link connection identifier. |
| fr-lsap | Local SAP address of the logical link connection on the CFRAD. |
| fr-rsap | Destination SAP address on the host. |
| pfid | (Optional) FID2 SNA transmission header for SNA peripheral traffic. |
| afid2 | (Optional) FID2 transmission header for APPN traffic. |
| fid4 | (Optional) Transmission header used on SNA subarea flows. |
[no] llc2 dynwind [nw nw-number] [dwc dwc-number]
Use the llc2 dynwind interface configuration command to enable dynamic window congestion management. Use the no form of this command to cancel the configuration.
| nw nw-number | (Optional) Specifies a number of frames that must be received to increment the working window value by 1. |
| dwc dwc-number | (Optional) Specifies the number by which the working window value is divided when BECN occurs. Valid numbers are 1, 2, 4, 8, and 16. 1 is a special value that indicates that the working window value should be set to 1 when BECN is indicated. The defult is 1. |
Use the show fras map privileged EXEC command to display information about the connection state in FRAS, as well as current BAN information configured.
Use the show fras map privileged EXEC command to display the mapping and connection state of Frame Relay access support.
