Ring Parameter Server (RPS)
RPS is a Token-Ring media-management function that resides on rings where
station operational parameters need to be centrally managed. RPS provides these
functions:
¹
It is the target of the Request Initialization MAC frames that are sent by stations
when they insert into the ring. This arrangement allows a station to send the
frame to a known address on the local segment without having to broadcast it
to other rings. The RPS can then inform a network management application
that a new station is present on the ring.
¹
It makes parameters, such as the ring segment number and ring station soft
error report timer value, available to all ring stations on the ring. This availability
guarantees that these values are the same for all stations on the ring.
Configuring the 8239 Model 1 to Support RPS
To use RPS, you must administratively enable both the Surrogate and RPS
functions and configure the 8239 Model 1 with a valid ring segment number. The
factory setting disables the Surrogate and RPS functions and there is no ring
segment number. To make the RPS operational, follow these steps:
¹
To configure the ring segment number, issue an SNMP Set request to the
appropriate object in the IBM TR Surrogate MIB or issue the SET
TR_SURROGATE SEGMENT_NUMBER terminal interface command.
¹
To enable RPS, issue an SNMP Set request to the appropriate MIB object in
the IBM TR Surrogate MIB or issue the ENABLE TR_SURROGATE
SURR_STATUS RPS_ADMIN terminal interface command.
¹
To enable the Surrogate Group, refer to “Configuring for the Surrogate Agent”
on page 4-7.
Note that the 8239 Model 1 RPS will not become active if either of the following
conditions exists:
¹
A valid ring number has not been configured.
¹
There is another RPS already on the ring that is using a different ring segment
number from that configured for the 8239 Model 1.
If another RPS is on the ring and that RPS is using the same ring segment number
as that configured on the 8239 Model 1, then the Model 1’s RPS will also be active.
A portion of the RPS function is to report when stations insert into the ring by
sending a trap. The factory setting for sending RPS traps is enabled. To send the
RPS traps to an IP station, set up an entry in the 8239 Model 1’s trap community
table by issuing an SNMP Set request to the appropriate object in the 8239 MIB or
issue the SET TRAP_COMMUNITY TR_SURROGATE terminal interface command.
To disable RPS from generating traps, issue an SNMP Set request to the
appropriate object in the 8239 MIB or issue any of the following terminal interface
commands:
¹
DISABLE TR_SURROGATE RPS_TRAPS
¹
SET MANAGEMENT_INTERFACE RPS_TRAPS DISABLE
