IBM 8239 Token-Ring Stackable Hub, Setup And User Manual

Page: 47 / 141

Changing the MAC address type to locally administered causes the
Management Interface to close and reopen its adapter.
¹
Set other Token-Ring options.
To set other Token-Ring network options, issue the appropriate SET
MANAGEMENT_INTERFACE command.
Configuring for Network Monitoring
To configure the 8239 for network monitoring, enter these commands.
1. If you are going to use in-band management, configure the 8239 according to
the instructions in “Configuring the 8239 for In-Band Connectivity” on page 4-5.
2. Enable the data-gathering functions that you need:
¹
To enable the 8239 for RMON, go to “Configuring RMON.”
¹
To configure the 8239 as a surrogate function, go to “Configuring for the
Surrogate Agent.”
Configuring RMON
To configure RMON:
¹
Assign IP information if you are accessing RMON information via in-band
connectivity. The RMON manager must have a physical path to the 8239’s
RMON probe.
¹
For security reasons, you may want to change the default community names
and set up access control lists
¹
If source routing is used on the segment and an RPS is not on the ring, you
must set the ring segment number in order for the RMON source routing
statistics to be accurate. For information about setting the ring segment
number, see “Enabling RPS” on page 4-8.
By default, all RMON groups are enabled and some RMON groups are set up
automatically. You can disable individual RMON groups using a terminal interface
command or via SNMP through the 8239 private MIB. For more information, go to
Chapter 7, 8239 Device Management.
Example: To configure the 8239 to communicate with an Nways Campus
Manager — Remote Monitor (ReMon), follow these steps.
1. Make sure that the 8239 Model 1 that is acting as an RMON probe is
configured with the appropriate IP information by using the DISPLAY IP
ADDRESS command. If a change is necessary, configure the IP information
using the following command:
set ip hub_id ip_address subnet_mask default_gateway
2. Follow the instructions provided with ReMon to configure or add a device or
probe.
Configuring for the Surrogate Agent
Enabling the Token-Ring surrogate function involves enabling the surrogate group
and, possibly, the CRS, REM, and RPS groups.
Note that almost all information associated with the surrogate agent can also be
accessed via SNMP through the IBM TR Surrogate MIB. Accessible only through
the 8239 MIB are:
