Examples of Network Management Systems
Some of the most common network management systems are listed below. All of them provide many
similar features, including network status displays showing key devices on a map, where the devices
change color if they have alarms, and with provisions for activating a remote paging device if there is
a problem.
WhatsUp Gold (Ipswitch Inc)
http://www.ipswitch.com/
USD 800 (approx)
SNMPc (Castle Rock Computing, Inc)
http://www.castlerock.com/
USD 900 to USD 2700 (approx, depending on options)
OpenView (Hewlett-Packard)
http://www.openview.hp.com/
USD 3,000 to USD 10,000
The OpenView product line has been revamped; HP is now positioning it not as a turnkey
software product, but as a custom adapted application to be bought through a value-added
implementation partner.

Management Information Base (MIB)
The
AR24027
implements only the core MIB-II. A management station will see three interfaces in the
interfaces group
:
1 - Bridge
2 - Ethernet
3 - Radio
The first of these represents the attachment of the SNMP agent to the bridged network. Only IP traffic
seen by the embedded host is counted.
The ethernet device (
ifIndex=2
) represents the traffic passing through the radio's ethernet port. This is
what should be tracked by MRTG.
The third device represents the wireless transceiver. If will appear as
down
if the radio does not have
a working link to its peer. This is useful for confirming the loss of a link. The traffic counts show all
packets to and from the radio, including handshaking between the two radios radios.
