  • Configuring VLAN Priority on Core Switches

    Configuring VLAN Priority on Core Switches

    With Per VLAN Spanning Tree (PVST) we configure a specific switch to become the root bridge for each VLAN. You can do this with the spanning-tree vlan X root primary command which sets the priority automatically, or you can set the priority manually with the spanning-tree vlan X priority command. A Virtual Local Area Network (VLAN) is a logical grouping that segments a network into smaller broadcast domains. VLANs allow you to separate network devices into distinct groups, even if those devices connect to the same physical switch or to different switches. All vlans exisit on all switches. The root bridge is the elected reference point from which all spanning tree paths are calculated. The vlan command in global configuration mode creates a new VLAN and updates an existing VLAN.

  • Are optical switches useful

    Are optical switches useful

    Optical switches are devices that selectively route optical signals from one channel to another without converting them to electrical signals. This transition allows data to remain in its native optical form as it travels through fiber optic networks, eliminating the need for. Optical switches, a key component in modern network infrastructure, are devices used in optical fiber networks for signal management. Unlike traditional electrical switches, which transmit data as electrical signals, optical switches handle data transmission in the form of light. This technology allows for high bit rate transmission to be switched between various optical lines.
