    SVCs require setup and tear down and are generally not available from Frame Relay carriers. Virtually all Frame Relay communications is done using PVCs. The Express 6100/6120 supports PVCs only. A number called the Data Link Connection Identifier (DLCI) identifies each virtual circuit within a shared physical channel.

  • Page 67: Frame Relay/Maintenance Protocol

    This parameter is the interval that the Express 6100/6120 polls the Frame Relay switch using the maintenance protocol selected above. The Express 6100/6120 is required to poll the Frame Relay switch pe- riodically to determine whether the link is active. The value is in sec- onds and ranges from 5 to 30 seconds with a default of 15 seconds.

  • Page 68: Dlci Mapping/Active

    Write security: 3, Read security: 5 When this parameter is set to Yes (def), the mapping is used to deter- mine the protocols used. If set to No, the Express 6100/6120 will ig- nore the virtual circuit with this DLCI.

    IP Map/Active Write security: 3, Read security: 5 When this is set to Yes (def), the Express 6100/6120 will attempt to transport IP packets for this DLCI. A setting of No means that no IP traffic or route will be exchanged.
  • Page 70 The virtual circuit may require an IP address to be specified at this DLCI interface. This is called a numbered interface. This address is used by the Express 6100/6120 to respond to Inverse ARP requests. If this IP address is left as 0.0.0.0, the link is treated as unnumbered and the Express 6100/6120 responds to the Inverse ARP with its Ethernet IP address.

  • Page 71: Dlci Mapping/Ipx Map

    IP Map/NAT The Express 6100/6120 can perform Network Address Translation over a PVC. Setting this option to On will cause the Express 6100/6120 to translate between the Ethernet addresses and the configured Link IP Address. Only one PVC may be used for translation at one time. If more than one IP Map is configured for NAT, the first PVC which is activated becomes the NAT port.

    IPX networks. The Type 20 IPX packet is used specifically for this purpose. This causes special handling of this packet by the Express 6100/6120.
