No not necessarily. This means that there are 3 Catalyst 2960's that are reachable through this port. These switches are likely daisy chained together, which is why they all show up under 1 port.

I daisy chain 3 2960 and connected to a one port on my 3560 and I only see 1 2960.

is CDP enabled on all of the switches?

I am looking at the sh cdp neighbor command on a 6509 switch. I am doing this remotely because the switch is 800 miles from where I am. I noticed that gig3/2 shows 3 Catalyst 2960. Does it mean that I have a hub connected to gig3/2? Thx

Cisco CDP Neighbor command

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.

Switches / Hubs

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

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
