Tapping a Link with G-TAP A Series 2

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.

2.

Reconnect the link so that data flows through the tap.

3.

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 .

4.

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

Note:  The above step is not applicable for G-TAP A-SF21.

5.

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

Note:  The above step is not applicable for G-TAP A-SF21.

6.

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

7.

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 in G-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 .
