Configuring SNA 9-17Configuring a Hunt Group for SNA SubscribersHunt groups are described on page 8-24. The function has some special requirementsfor SNA routing:l Each SNA port in a routing path must have a unique network address, even if itwill not be used explicitly by the routing table.l Configure two ports as SNA HPADs, one (called HPAD1 for this list) withRound Robin specified and one or more routing paths configured, and the otherport (HPAD2) with any routing algorithm but only one routing path.l The Port parameters for each port specified in the Routing Paths of each HPADmust contain a Remote Subscriber ID for any TPAD that might call eitherHPAD. (The Remote Subscriber ID in the HPAD's Port configuration is theLocal Subscriber ID in the TPAD's Port configuration.)l Include HPAD2 in HPAD1's routing path.l Configure only one routing path for each TPAD.l In Port configuration, disable Autocall for each HPAD and enable it for eachTPAD.l In Port configuration, configure HPAD1's Local Subscriber ID as the onlyRemote Subscriber for each TPAD.When the host polls the HPADs, they will become operational. The TPADs willautocall and the HPADs will connect to the TPADs by Round Robin. Since all theTPADs are configured to connect to HPAD1 (which has HPAD2 in its routing path),they will be connected to HPAD1, then HPAD2, then HPAD1, and so on.If HPAD1 fails, all calls will be routed to HPAD2 until HPAD1 is again operational.
