To disable an individual RMON group, issue an SNMP Set request to the
appropriate object in the 8239 MIB or issue the DISABLE RMON terminal interface
command. The DISABLE RMON command can also be used to disable all of the
RMON groups.
To determine which RMON groups are enabled, issue an SNMP Get request to the
appropriate object in the 8239 MIB or issue the DISPLAY RMON GROUP_STATUS
terminal interface command. When one or more RMON groups are enabled, RMON
Mode is displayed by the DISPLAY MANAGMENT_INTERFACE terminal interface
command; otherwise, DISABLED is displayed.
In order for source routing statistics to be accurate, the 8239 Model 1 must know
the ring segment number. If there is an external RPS on the ring, then no action is
required; otherwise, the 8239 Model 1 must be configured with the ring segment
number. A ring number needs to be configured if the ring segment number
displayed after issuing the DISPLAY MANAGMENT_INTERFACE command is 0.
To configure the segment number, use one of these commands or MIBs:
¹
SET TR_SURROGATE SEGMENT_NUMBER (IBM TR Surrogate MIB)
¹
ENABLE TR_SURROGATE SURR_STATUS SURR_ADMIN (8239 MIB)
Note: If you want to enable RPS on the 8239 Model 1, refer to “Ring Parameter
Server (RPS)” on page 8-16 for details.
Accessing RMON Information
To obtain RMON information, it is recommended that you use RMON Management
Software that provides a graphical user interface, such as IBM's Nways Manager
for AIX Remote Monitor or Nways Workgroup Remote Monitor for Windows NT.
The 8239 Model 1 also supports obtaining RMON information using the terminal
interface. This method is especially useful if there is a connectivity problem to your
RMON Management Software. The RMON-related terminal interface commands
are:
CLEAR RMON
DISPLAY EVENT_SCRIPT
DISPLAY RMON ALARM_DATA
DISPLAY RMON CONTROL
DISPLAY RMON EVENT_DATA
