Roy,
The Network Management Module (NMM) installed
in the 2072 provides port level SNMP management over
the 2072 and all repeater modules installed in the 2072.
The NMM support MIB I, MIB II , Repeater MIB (RFC 1516)
and the Asante MIB [available via anonymous ftp from
ftp.asante.com].
For complete details of the functionality of the Repeater MIB
and MIB II please see the respective RFC's [available via
anonymous ftp from ftp.uu.net].
Features of Asante MIB:
Traffic Monitoring: On a per port, per slot or per
segment basis the Asante MIB provides the capability
to monitor the following:
Collisions
Broadcasts
Multicasts
Fragments
Runts
Misaligned Closet
Long Closet
Short Event
Late Collision
Misaligned/CRC
Short Event/Missing SFD
Packet Size
Control: On a per port basis, the capability to
identify the curent state and enable or disable:
The Port
Link Integrity
Auto Partitioning
Polarity Correction
Low Threshold Receive
User Defined Thresholds: Thresholds may be defined
on a per port, per slot or per segment basis for any
of the traffic monitoring parameters (see above).
An exceeded threshold can either partition off the node,
sends an SNMP trap to an SNMP console or do both.
Thesholds can be set for rising or falling values.
Node Intrusion: Node Intrusion is defined on a per port
basis. It allows the specification of which physical
MAC (Media Access Control) address may access
the port. The presence of an invalid MAC address can
either partition off the node, sends an SNMP trap to
an SNMP console or do both.
Node Summary: Node summary provides information on up
to 12 devices connected to each port. The information
it provides on each address:
MAC Address
IP Address
Last Destination MAC Address
Protocol of Last packet Sent
Slot Number, Port Number
The time-out period for a device to be removed from
the table is user definable.
AUI Management: AUI ports can be enabled/disabled.
AUI ports with Asante Mini MAU transceivers offer
the same port level manageability found on repeater
modules.
Chassis Management:
Assign a module to either backplane segment
Partition a module off the backplane
Notification of Module Inserter
Notification of Module Removed
Notification of Fan Failure
Notification of failed power supply
(Redundant power configuration only).
2072 Management Console Options:
There are a variety of ways to take advantage of
the management capability of the NMM and the 2072:
AsanteView 2.2 for Windows 3.x
In-Band and Out-of-band (GUI Based)
AsanteView 2.2 for Mac
In-Band and Out-of-band (GUI Based)
Third Party SNMP Console (ex: Sun Net Manager,
HP Open View) supporting MIB II
(Text Based, Limited to managing only MIB II Parameters)
Third Party SNMP Console (ex: Sun Net Manager,
HP Open View) with Asante MIB Compiled
(Text Based)
AsanteView:
AsanteView is Asante's SNMP console for managing our
intelligent network equipment. (It can also 'get'
information from MIB II devices.) It can basically
'get' and 'set' all the information available in the
Asante MIB described above with an easy to use
graphical user interface that features auto-discovery,
map editing, Network Traffic Graphing, etc..
AsanteView also provides some high level features such as 'find
node' and 'find talker'. Find node allows you to enter
a MAC or TCP/IP address and AsanteView will identify
on which port on which hub that devise resides. Find Talked
does basically the same thing but for traffic parameters
(ex: list all ports generating an excess of 100 broadcasts
per second on my network.)
I hope this helps you understand what management capabilities are obtainable
with the 2072 and the Network Management Module via the Asante MIB. You may
want to check out the MIB II and Repeater MIB RFC's for more details on exactly
what capabilities they provide.
