Once the switches have been assigned a bridge ID and the protocol has chosen the root bridge switch, the best path to the root bridge is calculated based on port cost, path cost and port priority. [ 6 ] : 506 Ultimately STP calculates the path cost on the basis of the bandwidth of a link, however links between switches may have the same bandwidth.
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service.
The port becomes a trunk port even if the neighboring port does not agree to the change. Dynamic Auto — Makes the Ethernet port willing to convert the link to a trunk link. The port becomes a trunk port if the neighboring port is set to trunk or dynamic desirable mode. This is the default mode for some switchports.
In the extreme case (i.e. micro-segmentation), each device is directly connected to a switch port dedicated to the device. In contrast to an Ethernet hub, there is a separate collision domain on each switch port. This allows computers to have dedicated bandwidth on point-to-point connections to the network and also to run in full-duplex mode.

During an abortive attempt to update the NNTP standard in the early 1990s, a specialized form of NNTP intended specifically for use by clients, NNRP, [clarification needed] was proposed. [citation needed] This protocol was never completed or fully implemented, but the name persisted in InterNetNews's (INN) nnrpd program. As a result, the subset ...
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 ...
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 ...
