For a price much lower than a fully managed switch they provide a web interface (and usually no CLI access) and allow configuration of basic settings, such as VLANs, port-bandwidth and duplex. [29] [28] Enterprise managed switches (aka managed switches) have a full set of management features, including CLI, SNMP agent, and web interface. They ...
The next-most significant bit of the destination address is used to select the output of the switch in the next stage, and so on until the final output has been selected. For example, if a message's destination is PE 001, the switch settings are: upper, upper, lower. If a message's destination is PE 101, the switch settings are: lower, upper ...

Three PoE models. 10/100 ports plus one (9-port model) or two (all others) Dual Personality Ports (Gb or SFPs). Supports Layer 2 switching only. Single IP management clustering basic stacking supported.
Switches typically have no built-in method to indicate VLAN to port associations to someone working in a wiring closet. It is necessary for a technician to either have administrative access to the device to view its configuration, or for VLAN port assignment charts or diagrams to be kept next to the switches in each wiring closet.
The switch with the lowest priority of all the switches will be the root; if there is a tie, then the switch with the lowest priority and lowest MAC address will be the root. For example, if switches A (MAC = 0200.0000.1111) and B (MAC = 0200.0000.2222) both have a priority of 32,768 then switch A will be selected as the root bridge.

When a ZTP-enabled device is powered on, the device's boot file sets up configuration parameters. A switch then sends a request using DHCP or TFTP to get the device's configuration file from a central location. The file then runs and configures ports, IP addresses and other server parameters for each location. [2]
