DIAGNOSTICS AND STREAM STATISTICS

SNMP Configuration

SNMP (Simple Network Management Protocol), enables a management workstation or another SNMP client
application on the same LAN to communicate directly with Zephyr iPort PLUS, and for the iPort to initiate an
alarm on the network. Although the S in SNMP stands for Simple, the reality can be anything but. SNMP is a
complex utility, and the ground rules really depend on whatever SNMP Manager you are using. Be sure to read and
understand the instructions for your SNMP Manager. Having done all of that, it may also be a good idea to have a
current networking reference textbook close at hand.
Zephyr iPort PLUS will interface directly with an SNMP Manager. It communicates through an MIB (Management
Information Base) The MIB is a definition file that presents the management data in a more human-friendly
manner. Let's look at an example.
The raw data is ordered in a tree structure, where every item has a tree-based identifier, such as
"1.3.6.1.4.1.42463.1.11", for example. SNMP protocol itself can only deliver these raw numeric id's. The MIB
file associates meaning with the position in the tree. Now, if the same MIB is used at the both ends, you can better
understand what's going on. For example, if your SNMP client does not have MIB, it will display:
1.3.6.1.4.1.42463.1.11 = "2.0.0a"
On the other hand, if the Zephyr iPort PLUS MIB is uploaded to the SNMP client, it will display:
active software version = "2.0.0a"
Note that with the current firmware version, Zephyr iPort PLUS does not make its MIB file available for download-
ing.
