Overview of the Model 281xSA Hub
Support for SynOptics Optivity Features
1-6
The Model 281xSA hubs are fully compatible with network management
functions provided by the SynOptics Optivity network management software.
In particular, the Model 281xSA hubs support the Expanded View™,
Autotopology™, Show Nodes/Find Nodes, and Allowed Nodes features. These
hubs also allow the network administrator to set various thresholds for error
counters.
Expanded View
Expanded View offers extensive Ethernet fault, configuration, and performance
management from anywhere in the network.
Autotopology
Autotopology provides accurate realtime display of the physical layout of the
network by detecting and reporting all network management modules located
on the network. Model 281xSA hubs also provide IPX Autotopology in
addition to standard IP Autotopology.
The details of Autotopology vary according to the platform on which the
Optivity software is running. Consult the publications that were shipped with
your Optivity software for more information.
Show Nodes/Find Nodes
The Show Nodes command is an Optivity feature that displays a window
showing all the nodes in the current view and in any subviews. The Find Nodes
command is an Optivity feature that displays a window you can use to locate an
object by its name or media access control (MAC) address.
Allowed Nodes Security
The Allowed Nodes security feature prevents unauthorized nodes from
accessing the network. This node security function consists of the Intrusion
Control feature and the Allowed Nodes list.
Intrusion Control specifies whether or not the network management agent
should look for unauthorized addresses, and what action to take when one is
detected. This security feature can be applied at the hub, slot, or port level.
