Yes exactly.<br />
I mean that was the first thing I noticed.<br />
Good point Mr. David.

I currently have a survey that shows there's a Cat 2900 cisco switch that is racked. &nbsp;My show verison:<br />
<br />
Switch Ports Model &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SW Version &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;SW Image<br />

<br />
I'm thinking the survey may be outdated, but I was curious to see if there is a possibility that the 2900 Cat switch could have its image upgraded to the version/image above (3560). &nbsp;The switch from the pictures is a 24 port, and as you can see the output above says its a 48. &nbsp;<br />
<br />
<b>Is it possible to upgrade Cat 2900 to 3560 image? &nbsp;</b><br />
<br />
<b>What are the limitations when upgrading images on a cisco device? &nbsp;Ex: have to be same series, SW Version requirements 12.X(XX) or 15.X, License match?</b>

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.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
