Agent Software
The agent software resident on the Model 281xSA hub uses the information
collected by the LANIP chip to provide full management for the network
segment to which it is connected. The basic role of the agent software is to:
■
Gather statistics on network communications and activities.
■
Analyze and reduce the statistics and store them locally.
■
Communicate with the management station to transfer the collected
statistics; provide configuration, status, and control information; or act on
requests from the management station.
Teamed with the SynOptics network management software—or other SNMP-
compatible network management software—the network management agent
allows you to observe and configure the following items:
■
Flow and quality of network data
■
Network topology
■
Physical components, such as cables and hubs
■
Faults, errors, and hardware status
This level of network management also enables you to detect and correct
network faults, as well as to isolate, monitor, and reconfigure specific network
branches.
The Model 281xSA hubs store the agent software in onboard flash memory.
This feature allows software upgrades to be handled over the network from a
central management station and eliminates the physical swapping of ROMs.
The Model 281xSA hubs support both IP and IPX network management. IPX
support enables network managers to install and manage Model 281xSA hubs
in Novell Netware environments without needing to learn and administer IP
networking principles.
MIB-II
MIB-II allows any vendor’s network management station to query important
system configuration information, as well as IP and SNMP counters and
statistics. The Model 281xSA hub supports MIB-II groups including system,
interfaces, address translation, IP, ICMP, UDP, and SNMP.
