Checking the Installation
After you have connected iLink Agg, verify that it is
functioning correctly.
• Check that the power LEDs are illuminated.
• Check the link LEDs for each of the connected ports to
verify that the links are connected and traffic is present.
Doubling Your Ports
By using simplex (single fiber) cables, fiber ports can
be used as Span network inputs and monitor outputs
simultaneously, making up to 24 network and 24 monitor
ports available for use. This can be done because the TX
and RX sides of the ports are completely independent.
Mapping Ports
The iLink Agg is shipped in a configuration that aggregates
the traffic from the 16 network ports and regenerates it to
the 4 monitor ports. A variety of alternate configurations
are preloaded; they can be viewed by typing
config list
and loaded by typing
config load file=
<configuration
name>
followed by
commit
. See the User Guide for
diagrams of the preloaded configurations.
You can create your own configurations, mapping traffic
from any set of ports to any set of ports. For example,
to aggregate 4 network ports to 1 monitor port and the
other 12 network ports to 3 monitor ports, use these
commands:
map discard
# clear the current configuration
map add in_ports=n1.1-n1.4 outports=m.1
map add in_ports=n1.5-n1.16 outports=m.2,m.3,m.4
commit
config save file=myConfig
# save the cofiguration for
future use
“myConfig” Port Mapping
Note: Each network input can be used in only one
in_ports list.
commit
must be executed to activate the
added maps.

Simplex cables
Connecting to the Network
Note: SFP modules may be shipped separately. An
appropriate cable is shipped with each SFP module.
To connect iLink Agg to a Span port or external Tap on
your network:
1. Remove the temporary plug from an SFP slot and insert
the SFP module until it clicks into place. The SFP slot
can be a network port on a Span model iLink Agg or a
monitor port on any model.
2. Connect the cable supplied with the SFP module to the
SFP port.
3. Connect the other end of the cable to a Span port on a
network switch. Alternately, it can be connected to an
external Tap or Port Aggregator Tap.
To connect iLink Agg in-line to your network:
1. Connect any odd-numbered network port on in-line
model iLink Agg to an appropriate network cable.
2. Connect the other end of the cable to one side of the
network link you are tapping.
3. Connect the next higher even-numbered network port
to an appropriate network cable. In-line port pairs are
located side-by-side.
4. Connect the other end of the cable to the other side of
the network link you are tapping. The Tap connection
is fully passive – if the iLink Agg loses power, traffic
continues to flow in the link.
Connecting to Monitoring Devices
To connect iLink Agg to a monitoring device:
1. Remove the temporary plug from an SFP slot and
insert the SFP module until it clicks into place. The SFP
slot can be a network port on a Span model iLink Agg
or a monitor port on any model.
2. Connect the cable supplied with the SFP module to the
SFP port.
3. Connect the other end of the cable to the monitoring
device.
Note: Span network ports can also be used as
monitoring outputs, and monitor ports can also be used
as Span network inputs.
