Using an SNMP Manager
Once the SNMP communities are established, you can connect to the Access Gateway via the
Internet using an SNMP client manager (for example, HP OpenView). SNMP is the standard
protocol used in the Network Management (NM) system. This system contains two primary
elements:

Manager – The console (client) through which system administrators perform
network management functions.

Agent – An SNMP-compliant device which stores data about itself in a Management
Information Base (MIB). The Access Gateway is an example of such a device.
The Access Gateway contains managed objects that directly relate to its current operational
state. These objects include hardware configuration parameters and performance statistics.
Managed objects are arranged into a virtual information database, called a Management
Information Base (MIB). SNMP enables
managers and agents to communicate with each other
for the purpose of accessing these MIBs and retrieving data. See also, “Installing the Nomadix
Private MIB” on page 76 .
The following example shows a (partial) SNMP screen response.
Using a Telnet Client
There are many Telnet clients that you can use to connect with the Access Gateway. Using
Telnet provides a simple terminal emulation that allows you to see and interact with the Access
Gateway’s Command Line Interface (as if you were connected via the serial interface). As with
any remote connection, the network interface IP address for the Access Gateway must be
established (you did this during the installation process).
