Why Manage Your
Stack?
With management, you can change and view the way the stack or
network operates in the following way:
■
Display a graphical representation for the stack to quickly view the
status of each hub and its ports.
■
Display general information for the stack or hubs.
■
Graphically display network information for the stack’s cascaded
segments.
■
Enable and disable ports, and switch them between segments.
■
Perform load balancing so that the traffic is distributed evenly across
the segments in the stack, resulting in more efficient segments.
■
Configure security for the ports, including specifying what
equipment is allowed to communicate through the ports on the
hub.
■
Set up resilience; specify a backup connection that takes over should
a main connection fail.
■
View statistics.
■
Configure the console port for connection to a modem.
■
Configure user management access levels.
■
Upgrade the management software in the stack with any future
agent software upgrade.
■
Configure the stack to send messages (called
traps
) to an SNMP
network management application (for example, Transcend ®
Enterprise Manager) if certain conditions arise — you cannot
configure this using the web interface.
■
Perform remote monitoring using RMON — not manageable using
the web interface or Quick Config Manager.
■
Restart the hub to refresh its statistics and use any new
configurations.
■
Initialize the hub to return it to its factory settings (IP information is
retained).
