Finding Agents for Data Collection 53
To enable you to manage large numbers of collection agents, agent
folders can be created in the tree and the agents dragged and dropped
into them.
Adding and Editing Agents
From the Configure Agents dialog box you can use Traffix Manager to
automatically find agents on your network, or you can add agents
yourself. You can then add these new agents to the list in the agent tree.
To add an agent manually you need to know the IP address and
community string of each new agent.
Community strings, also known as community names, are used to limit
access to an agent’s
MIB . The MIB becomes accessible only to a selected
set or community of management workstations. Management stations
require level 4 access to MIBs. Level 4 provides the highest level of access.
See
Table 6 for more information.
A duplicate agent is one with the same IP address and community name
as another agent in the agent tree. Traffix Manager does not support
duplicate agents. Duplicate error checking is handled by the Add Agent
dialog box. If an invalid (duplicate) IP address or community string is
entered, an error message appears.
When Traffix Manager retrieves agent details, a list of the interfaces on
that agent is displayed. You select the interfaces you wish to collect data
from, and add the newly-configured agent to the agent tree.
The agent will be added to the currently selected agent folder in the tree.
If no folder is selected, the agent will be added to the top-level
All folder.
