Hi, <br />
<br />
We currently have a Catalyst 4000 series switch. When the switch is power cycled we have to type in the word 'boot' for it to load the configuration and become functional. <br />
<br />
Can anybody please explain to me how we can have the switch load without having to type in this commnad?<br />
<br />
Thanks,

Cisco Catalyst Needs 'boot' command to start

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
