1UL-IP/T, DCLog Xpress-I Server, Order Information

There are two common methods to extract traffic directly from the network: TAPs and SPANs. A network TAP is a hardware component that connects into the cabling to copy packets for call recording purposes. A SPAN is a software function of a switch or router that duplicates traffic from incoming or outgoing ports and forwards the copied traffic to a special SPAN (or sometimes called mirror) port. Here are some minuses of SPAN.
● SPAN ports are easily oversubscribed and have the lowest priority when it comes to forwarding,                 which results in dropped packets
● The SPAN application is processor-intensive and can have a negative performance impact on the                switch itself, possibly affecting network traffic
● Because SPAN traffic is easily reconfigured, SPAN output can change from day to day, resulting in              the inconsistent.
