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.

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 Nortel 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.

CRS supports the following functions:

• Station Status Request Function

• Set Station Parameters Function
