The CML/NM communicates any events or modification when polled by the
management station. The CML/NM is the RADring hub module equivalent
to the Token Ring Management Adapter (TMA) which is the agent for
S-TAUs and F-TAUs. RADring hubs and TAUs can be managed under the
same RADview management station.
In addition, the management card features power supply monitoring LEDs to
indicate the power supply status for the hub, a LAMP TEST push-button to
check all the indicator LEDs of the hub modules, and a RESET button to
initialize the hardware and software. The CML/NM has a seven segment
status display which provides status information regarding the RADring and
the Token Ring network.
CML/IB In-Band
Network
Management
Module
The CML/IB module is an in-band management agent. It is a fully compliant
SNMP agent, supporting MIB II with private extensions.
The CML/IB enables full management of the network and allows extensive
monitoring and control from RADview management station, or any generic
SNMP management station.
The CML/IB single slot RADring module provides four major management
functions: Network monitoring, Network control, Advanced intelligence and
IBM LAN Manager/NetView support.
Network Monitoring
The CML/IB monitors the LAN, collecting LAN status, statistics and error
information for retrieval by the management station. To provide monitoring,
a CML/IB card must be inserted in each ring, or connected to the Ethernet
segment.
Network Control
The CML/IB enables full control of the RADring hub from the management
station. It acts, in conjunction with the CML/NM, upon management
commands received over the network. The CML/NM supports up to two
CML/IB modules, enabling management of two separate rings in the same
hub and another CML/IB-E.
Advanced Intelligence
The CML/IB provides advanced intelligence features including self-healing
and automatic recovery from network failure. These recover the network
from a beaconing state without the connection of a management station.
Maximum network up-time and minimum interference is ensured. In
addition, for increased manageability and network security, the CML/IB
performs a correlation between the station MAC address and the actual
physical connection of the station. Security can be provided on each port by
enabling access to only predefined addresses.
