a function that copies packets sent or received on a specific port to another port. A monitoring device such as Sniffer or Rmon probe can be attached to a port to analyze the details of the packets that pass through the source port
A system that allows you to copy the traffic from one port on a Switch to another port on the Switch. Port mirroring is used when you want to monitor the physical characteristics of a LAN segment without changing the characteristics by attaching a monitoring device.
Port mirroring allows you to copy traffic from one port to another port in order to examine the first port's raffic without interfering with it.
A switching feature that allows one port's media access control (MAC) layer data to be replicated to another port for monitoring by a network analyser.
Monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from one port to a monitoring port. For more information on port mirroring, see Defining Port Mirroring Sessions.
Port mirroring allows a switch port to monitor packets from any or all of its ports so that traffic can be analysed. Quality of Service (QoS) Some switches support QoS (per 802.1p and 802.1Q standards) whereby messages can be assigned levels of priority. QoS is important where time-critical applications can be impaired by data delays.
Port Mirroring allows a switch port to monitor packets from any or all of its ports so that traffic can be analyzed. See a tutorial on Port Mirroring
Method in which a copy of an IPv4 packet is sent from the routing platform to an external host address or a packet analyzer for analysis.
Port mirroring is used on a network switch to send a copy of all network packets seen on one switch port to a network monitoring connection on another switch port. This is commonly used for network applicances that require monitoring of network traffic, such as an intrusion-detection system. Port mirroring on a Cisco Systems switch is generally referred to as Switched Port Analyzer (SPAN); some other vendors have other names for it, such as Roving Analysis Port (RAP) on 3 Com switches.
