SPAN Series Overview — The

VERSAstream

™

SPAN aggregator/regenerator provides a single turnkey solution for

24x7 monitoring of redundant, failover, two-link EtherChannel and asymmetric net-

work segments. It provides the ability to monitor one or two SPAN ports simultane-

ously, aggregating the data, and sending a single copy to two, three, four, six or eight

connected network devices.

For example, instead of deploying two network devices connected to two network

taps, simply insert the VERSAstream

™

SPAN aggregator/regenerator into a pair of

SPAN ports, where you want to connect your monitoring or analysis equipment, and

you can instantly begin collecting data from both SPAN ports simultaneously with as

little as one network monitoring tool. It's that simple. No other configuration is nec-

essary.

Asymmetric routing, EtherChannel, and load-balanced environments use multiple

paths to send data, reassembling it as the data reaches its destination. The

VERSAstream

™

SPAN aggregator/regenerator makes monitoring and analyzing mul-

tiple data paths less of a challenge for network managers. The VERSAstream

™

SPAN aggregator/regenerator aggregates the two streams of data it receives, so net-

working professionals can receive all the data they need with as little as one tool and

one trace file.

Redundant networking systems, used in the event of cable or hardware failure, no

longer require more than one device to receive data from both network segments.

Leave your monitoring and analysis tools hooked up 24x7 with no need to manually

switch or move connections. If one network segment, switch, or SPAN port fails or

needs reconfiguration, the VERSAstream

™

SPAN aggregator/regenerator will still be

able to collect data from the secondary segment, so you will never miss a single

packet.
