Cable the Monitoring ports
Connect to the network devices you will be monitoring through the Sensor Monitoring ports. You can
deploy Sensors in the following operating modes:
• In-line mode (fail-closed) • SPAN or Hub mode
• In-line mode (fail-open) • Failover
• External tap mode
How to use peer ports
All full-duplex Sensor deployment modes require the use of two peer monitoring ports on the Sensor.
On the Sensors, the numbered ports are wired in pairs to accommodate the traffic.
The following SFP Gigabit Ethernet ports are coupled and must be used together:
Port Pairs Transceiver Type
1A and 1B SFP
2A and 2B SFP
3A and 3B SFP
4A and 4B SFP
5A and 5B SFP
6A and 6B SFP
7A and 7B SFP
8A and 8B SFP
9A and 9B SFP
10A and 10B SFP
You cannot configure, for example, 1A and 2A to work together as a pair.
