Tapping a Link with G-TAP A-TX21

To tap a link with G-TAP A-TX21 follow the below steps :

1.

Disconnect any existing link between two network devices , example; a connection between an access switch and a distribution network.

1.

Reconnect the link so that data flows through the tap.

2.

Connect the test traffic to Network A / B ports, close with tap relay in passive mode, and verify that traffic flows through the G-TAP .

3.

Once the traffic flow is confirmed in passive mode, switch it back to active mode and connect the production link.

4.

Connect the Ethernet cable from one network device to the Network A port.

5.

Connect another cable from the second network device to the Network B port.

6.

Connect the Monitor/Tool ports either to a network analysis tool or to a GigaVUE data access switch for intelligent distribution to multiple tools.

G-TAP A-TX21 Data Flow per Group

Once the tap is operating successfully in active mode, traffic is sent to the Monitor/Tool ports, as shown inG-TAP A-TX21 Data Flow per Group . If the primary sources of power is lost and backup battery drops to 5 percent of charge capacity , then G-TAP A-TX21 will automatically close its relays and switch back to passive mode .
