Chapter 8. Network Management
The 8239 contains network management functions to assist in managing networks
and providing information that can help you analyze and optimize your network's
performance, prevent outages, and troubleshoot problems. Token-Ring media
management as well as higher-layer protocol management is supported. Network
management support is provided only by the 8239 Model 1. Information is provided
for a network only when the 8239 Model 1’s Management Interface is inserted into
the network being monitored.
This chapter contains information on how to access the network management data
from an 8239 Model 1 and provides details about the following network
management functions that are supported by the 8239 Model 1:
¹
IEEE 802.5 Token Ring MIB (RFC 1748)
¹
MIB II (RFC 1213)
¹
Remote Monitoring (RMON)
– RMON MIB (RFC 1757)
– Token Ring Extensions to the RMON MIB (RFC 1513)
¹
RMON 2
– RFC 2021
– RMON MIB Protocol Ids (RFC 2074)
¹
Enterprise Communications Analysis Module (ECAM)
¹
IBM Token Ring Surrogate MIB and Surrogate Trap MIB
– Configuration Report Server (CRS)
– Ring Error Monitor (REM)
– Ring Parameter Server (RPS)

Reference.
Accessing Network Management Data
You can use in-band and out-of-band access to the 8239 Model 1 to configure it to
support the various network management functions and to obtain the network
management information from the Model 1.
¹
In-band access is provided via:
– A Telnet session using the terminal interface
– SNMP using the appropriate MIB
To configure the 8239 Model 1 for in-band connectivity, refer to “Configuring
the 8239 for In-Band Connectivity” on page 4-5.
¹
Out-of-band access is provided through the EIA-232 connection using the
terminal interface. To configure the 8239 Model 1 for out-of-band connectivity,
refer to “Out-of-Band Connectivity” on page 7-1.
The network management information collected and analyzed by the 8239 Model 1
can be obtained directly only from the Model 1 that is monitoring the network. A
request for network management information cannot be issued to one 8239 Model
1 to retrieve information from another Model 1 in the same stack. To obtain the
network management information from an 8239 Model 1, the request must come
from either that Model 1’s EIA-232 interface (out-of-band access) or via a
