16. 1 13 Configuring LNM Services Ring Parameter Server RPS The Bay Networks implementation of RPS is one of five LAN management servers you configure on a token ring circuit RPS provides the following main services e Sends initialization information to new stations that are attaching to the ring e Ensures that stations on the ring have consistent values for operating parameters e Forwards registration information from stations attaching to the ring to the IBM LAN Network Manager application RPS also supports the following functions e Status Request Function Ring Station Parameters Maintenance Function e Registration Function RPS Activation Function Status Request Function The RPS Status Request Function accepts and executes requests for status from the IBM LAN Network Manager application Ring Station Parameters Maintenance Function The RPS Ring Station Parameters Maintenance Function issues commands to set parameter values in ring stations The ring station operational parameters controlled by RPS are e Ring number e Soft error report timer Registration Function The RPS Registration Function accepts unsolicited registration information from ring stations and forwards this information to the IBM LAN Network Manager application through LRM RPS also responds to the station s request for registration by sending the current values for the ring s operational parameters to the requesting station 30353
17. 4 A Rev 00 LNM Servers Overview RPS Activation Function When a Ring Parameter Server becomes active on a ring it determines if another RPS is already active on the ring If another RPS is not active on the same ring the RPS in the attaching station activates its Ring Station Parameters Maintenance Function It then broadcasts an Initialize Ring Station MAC frame a predetermined number of times to all stations on the same ring This mechanism facilitates the establishment of default ring operational parameters If another RPS is already active on the same ring the new RPS compares the values received for the ring s operational parameters with its own stored values If the values match the RPS activates its RPS function If the values do not match the new RPS reports that its parameters are inconsistent with the existing parameters for the ring The RPS then disables its own functional address to prevent it from receiving requests for initialization from stations attaching to the ring Configuration Report Server CRS The Bay Networks implementation of CRS is one of five LAN management servers you configure on a token ring circuit CRS accepts commands from the IBM LAN Network Manager application to get station information set station parameters and remove stations on the locally attached ring CRS also collects and forwards configuration reports generated by stations on the local ring to the IBM LAN Network Manager application
