Managing the Ethernet Segment Cascade Connection
When you connect 10Mbps and 100Mbps equipment to the unit,
the ports are automatically connected to the relevant segment.
The segment switch joins the 10Mbps and 100Mbps segments so
that all of the equipment connected to the segments can
communicate.
By default, the Dual Speed Hub 500 is configured so that all of its
segments are connected, and its switch is in 'AutoConfigure' mode.
This ensures that all equipment connected to the stack can
communicate through the stack. Only alter these settings if you want
to alter the operation of the unit's switch. See
Switch Between Segments"
This command allows you to connect or isolate a labeled segment
to/from the cascaded segment of the same speed connected to other
units in the stack.
Isolating the segment means that traffic received by the unit is not
passed on to other units in the stack.
Traffic may be passed on by the segment of the other speed, if that
segment is not isolated and the unit's segment switch is operational.
If you have a Dual Speed Hub 500 with a serial number less than
0600/00000000000, upgrading the software to version 2.1x or
above will not give you support for segment isolation.
