Using SNMP
You can use SNMP to find out about licensing service events on your network.
About SNMP and NLS
SNMP is a management interface and high-level protocol. General-purpose
protocols such as IPX
TM
, TCP/IP, and UDP can host SNMP. NLS takes events
and errors, wraps them in one of these protocols, and sends them to a
management utility or console.
For example, suppose you instruct SNMP to raise an event whenever a license
unit is conveyed to a User object. Every time a license unit is conveyed,
SNMP sends a packet to a management console. The console registers that
event. As network administrator, you can view these packets at the
management console.
With SNMP, you can send out a wide variety of different events. NLS
provides a list of events and errors that the licensing service can send out
notifications on. As network administrator, you choose the events that you are
interested in. You can turn off all events, turn them all on, or turn on selected
events.
For example, NLS sends broadcast messages. Using SNMP, you can send an
SNMP message with the same content to a management console.
In short, SNMP enables you to be aware of what's happening on the network.
Why You Need a Management Console
An SNMP management product—for example, OpenView* or
ManageWise
®
— resides on the network and registers itself as the
management console. An SNMP agent (SNMP.NLM) runs on a NetWare
server. The SNMP pieces on each server send the SNMP datagrams to the
console. You use the console to track what's happening on the network.
You can place the management console anywhere on the network. This
console reads the SNMP packets and displays their contents to you, as the
network administrator. Typically these consoles are run on client computers
for convenience, but that functionality can be implemented on any computer
on the network.
