Port mirroring on a Cisco Systems switch is generally referred to as Switched Port Analyzer (SPAN) or Remote Switched Port Analyzer (RSPAN). Other vendors have different names for it, such as Roving Analysis Port (RAP) on 3Com switches. Network engineers or administrators use port mirroring to analyze and debug data or diagnose errors on a ...
Another method to monitor networks is to use port mirroring (called "SPAN", for Switched Port Analyzer, by vendors such as Cisco, [1] and given other names, such MLXe telemetry by Brocade Communications and other vendors)(also known as MIRROR port) or a monitoring protocol such as TZSP on routers and switches. This is a low-cost alternative to ...
Port mirroring is how this problem is addressed in switched networks: In addition to the usual behavior of forwarding frames only to ports through which they might reach their addressees, the switch forwards frames received through a given monitored port to a designated monitoring port, allowing analysis of traffic that would otherwise not be ...
If another switch is connected, the port may remain in blocking mode if it is determined that it would cause a loop in the network. Topology change notification (TCN) BPDUs are used to inform other switches of port changes. TCNs are injected into the network by a non-root switch and propagated to the root.
On modern networks, traffic can be captured using a network switch using port mirroring, which mirrors all packets that pass through designated ports of the switch to another port, if the switch supports port mirroring. A network tap is an even more reliable solution than to use a monitoring port since taps are less likely to drop packets ...
A different slave becomes active if, and only if, the active slave fails. The single logical bonded interface's MAC address is externally visible on only one NIC (port) to simplify forwarding in the network switch. This mode provides fault tolerance. XOR (balance-xor) Transmit network packets based on a hash of the packet's source and destination.
Using port mirroring (sometimes called Span Port) is a very common way, as well as physically inserting a network tap which duplicates and sends the data stream to an analyzer tool for inspection. Deep Packet Inspection (and filtering) enables advanced network management , user service, and security functions as well as internet data mining ...
A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off ...
