LCM responds:
Name: a
Ports: 1, 2, 3, 11, 12
Type: All
2. To create workgroup B on ports 5, 7, 15:
FN100 > workgroup B 5,7,15
LCM responds:
Name: b
Ports: 5, 7, 15
Type: All
Port 11 has been assigned to a segment that includes hosts that belong to
workgroup A and workgroup B. Port 12 connects workgroup A to the
router and port 15 connects workgroup B to the router.
3.11 LOCAL ADDRESS FILTERING
The localfilter command determines whether the per-port filtering of
local addresses is performed by hardware or software. The option you
choose depends on the type of performance you want and the application
of your FN100. Options include:
hardware - local address filtering performed by hardware. This option is
a good choice in environments where the FN100 is primarily handling
local traffic. This option provides optimal buffer utilization, but with
limited observability into packet error statistics. You would most likely
use this option if you were connecting the FN100 to devices such as
concentrators.
software - local address filtering performed by software. This option is a
good choice when you want greater observability of packet error
statistics, and in environments with less local traffic. However, this option
does not maximize buffer utilization efficiency. You would most likely use
this option if you were connecting the FN100 to devices such as switches
and user nodes.
The full syntax for the command is as follows:
localfilter <PORTS> <hardware|software>
