ExifTool is a Perl module with an included command-line application for reading and writing meta information in image, audio, and video files.Since then, exiftool has become the go-to tool for working with metadata at the command line due to the vast array of file formats and types of metadata it supports.

Generally, only uplink ports can be used to achieve switch uplinkĮach stack member shares a single IP address and acts as a whole unit Through dedicated stacking ports (when a switch has) or through uplink portsĪny port can be designated as a trunk port to realize switch trunking You can just add as many switches for uplink based on your needs Switch uplink is flexible in the number of switches. You can just add as many switches for trunking based on your needs Switch trunking is flexible in the number of switches. Switch stacking is stricter about the number of switches to be stacked(different vendors may have their own standards) Switch uplink offers a perfect fit for connecting switches from the different product family Most network switches support trunking regardless of models or vendors, ensuring connections between different VLANs #DIFFERENCE BETWEEN UPLINK AND DOWNLINK PORTS SERIES#Switch stacking requires the same model or series of Ethernet switches from one vendor The ports of the switches can't be superposed The port density of a stack unit is the sum of the combined ports The table below shows the differences among switch stacking vs trunking vs uplink. Switch Stacking vs Trunking vs Uplink: What Are the Differences? This is where the difference between switch stacking vs cascading lies.įigure 3: Switch Uplink with FS S3910-24TS, S5860-20SQ, N8560-48BC If you connect two uplink ports via straight-through cable, the result is the same as using two normal ports - makes the devices fail to communicate. When you connect two devices, the uplink port on only one of them is used. As shown below, to build uplinks to achieve high availability for campus networks, connect the uplink port on one switch to the standard port on another uplink switch to help expand the network’s size, and a 3-layer cascading are implemented. Uplink ports often have relatively higher data rates than normal ports and are used to connect larger networks via a straight-through cable or direct attach cable. Switch uplink is a subjective concept which means that the cascading of ports between two switches is facilitated via a so-called “uplink port”. In the VLAN trunking link, each switch has a port designated as a trunk port to allow data flow between these VLANs.įigure 2: VLAN Trunking with two FS S3910-48TS 48-Port Switches There is a single communications channel (VLAN trunk link) between the two switches, over which traffic for both VLANs can pass. Just as the figure below shows, each trunk switch is configured with 2 VLANs (10 and 20). It enables packets encapsulated for multiple VLANs to cross exactly the same port and then retains the traffic separation among them. Based on layer 2 technology, trunking is often used to form internetwork including LANs, VLANs, and WANs. It is similar to the structure of a tree with one trunk and many branches. Switch trunking refers to a method that a network system provides network access to many switches by sharing a set of links instead of providing them individually.

The performance of the whole network system has been largely enhanced, so has the management for these switches. #DIFFERENCE BETWEEN UPLINK AND DOWNLINK PORTS FULL#The port density of a stack unit is the sum of the combined ports and the switching capacity will be much augmented as stacking connects the backplane of the switches thus having full backplane speed connectivity between the switches. And stacking can be achieved only between the same switch models or the same series of a brand, like between FS S5860-20SQ switches or mixed stacking for S5860-20SQ and S5860-24XB-U switches shown in the figure below. Switch stacking is to combine multiple stackable switches via a dedicated stacking port and stack cable to operate as one logical unit and share the same IP address.Not all network switches support stacking, it depends on different brands. What Are Switch Stacking, Switch Trunking, Switch Uplink? This post aims to elaborate on the three switch connection methods and indicate which one to choose in practice. There are various approaches to connect multiple switches, among which switch stacking vs trunking vs uplink are the most prevailing ones. Normally, in a network system, several network switches are combined together to meet network needs (port number, certain functions, etc.) when one switch can't.
