IBM 8239 Token-Ring Stackable Hub, Руководство по установке и эксплуатации

Страница: 115 / 141

The administrative state of the server functions indicate whether or not you want
the servers to be active. The operational state of the server functions indicate
whether or not the servers are active.
Configuration Report Server (CRS)
CRS accumulates information by MAC address about what stations are on the ring,
handles requests to set and display ring-station information, and removes stations
from the ring on request. CRS can also provide real-time information when the ring
segment topology changes.
CRS provides these functions:
¹
Allows active management of Token-Ring networks, gathering station
information, and setting station parameters
¹
Provides an accurate display of all station MAC addresses on the ring being
monitored and their order on the ring for generating network topology
¹
Reports ring topology changes
Configuring the 8239 Model 1 to Support CRS
You must administratively enable both the Surrogate and CRS functions to use
CRS.
¹
To enable CRS, issue an SNMP Set request to the appropriate MIB object in
the IBM TR Surrogate MIB or issue the ENABLE TR_SURROGATE
SURR_STATUS CRS_ADMIN terminal interface command.
¹
To enable the Surrogate Group, see “Configuring for the Surrogate Agent” on
page 4-7.
Part of the CRS function is to report ring topology changes by sending a trap. The
factory setting for sending CRS traps is enabled. To get the CRS traps sent 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 CRS from generating traps, issue an SNMP Set request to the
appropriate object in the IBM TR Surrogate MIB or issue the DISABLE
TR_SURROGATE CRS_TRAPS terminal interface command.
Accessing CRS Information
The CRS group is formed by the CRS Status Table and the CRS Ring Station
Table. Both of these tables can be accessed via SNMP using the IBM TR
Surrogate MIB or by issuing the following terminal interface commands:
¹
DISPLAY TR_SURROGATE CRS_STATUS
¹
DISPLAY TR_SURROGATE CRS_STATION
¹
SET TR_SURROGATE CRS_STATION
Ring Error Monitor (REM)
REM provides the following functions:
¹
Observes collects, and analyzes hard and soft error conditions on the ring
¹
Assists in fault isolation and correction
