Roving analysis port

A network can be monitored using a technique called port mirroring. When port mirroring is enabled, each data packet that comes into or out of a specific switch port is copied and sent to a destination port. Once the copied packet reaches the destination port, it can be examined by a security application or monitored by software. Following implementation, mirroring can alert administrators to network problems and contribute to troubleshooting. Port mirroring and managing switch ports are set up by administrators or through a security application.

Port mirroring is an approach to monitoring network traffic that involves forwarding a copy of each packet from one network switch port to another. You forgot to provide an Email Address. This email address is already registered. Please login. You have exceeded the maximum character limit.

Port mirroring is used on a network switch to send a copy of network packets seen on one switch port or an entire VLAN to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic such as an intrusion detection system , passive probe or real user monitoring RUM technology that is used to support application performance management APM. Network engineers or administrators use port mirroring to analyze and debug data or diagnose errors on a network. It helps administrators keep a close eye on network performance and alerts them when problems occur. It can be used to mirror either inbound or outbound traffic or both on single or multiple interfaces.
