Ensuring complete visibility of network data is the first critical component of analysis.
There are two common ways for a monitoring device to access network traffic: using a switch’s SPAN session (also known as port mirroring) or a network TAP (Test Access Port).
Because of their nature, network TAPs have significant benefits over the use of SPAN ports:
•Taps do not alter the time relationships of frames.
•Taps do not introduce additional jitter or distortion.
•VLAN tags are not normally passed through the SPAN port.
•Taps do not groom data nor filter out physical layer error packets.
•Short or large frames are not filtered.
•Bad CRC frames are not filtered.
•Taps do not drop packets regardless of the bandwidth.
•Taps are not addressable network devices and cannot be hacked.
•Taps are passive and fault tolerant.
•Taps do not care if the traffic is IPv4 or IPv6, it passes all traffic through

Network Copper Tap, C8-1G The C8-1G tap enables transparent monitoring of full and half duplex 10/100/1000BaseT network communications. Unlike SPAN ports, the C8-1G tap monitors all seven (7) protocol layers and any packet size, including errors. Redundant power and Permanent Network Link features that transfer any network link failure to active auto-negotiation or redundant path, provide maximum monitoring time and uninterrupted network connectivity in the event of a power failure.
Network Copper Tap, C1-1G Simena’s C1-1G is a passive, half/full duplex Tap for 10/100/1000BaseT networks. Once in place, it enables the monitoring of half/full duplex packet traffic and allows the moving of test equipment without breaking the circuit. Because it is passive this tap will mirror full duplex traffic, as if monitoring devices were in-line, while being fully transparent to network devices. The Permanent Network Link feature guarantees permanent network connectivity even in the event of a power failure. Unlike SPAN ports, this tap can monitor all seven (7) protocol layers and any packet size including errors. It is rack mountable with a daisy chain power supply feature for powering multiple units, and works at distances over 100 meters (300 feet). Because the tap requires no IP address it is completely non-intrusive and 100% secure. General Features |
