Connect 3 Cisco switches via ethernet ports?



As an IT admin, connecting three Cisco switches via Ethernet ports is a task that requires a certain level of technical knowledge. To successfully accomplish this task, it is important to understand the basics of networking and have a basic understanding of the different types of Ethernet connections.

The first step in connecting three Cisco switches via Ethernet ports is to identify the type of Ethernet connection that will be used. There are two main types of Ethernet connections: a direct-connect connection and a cross-over connection. A direct-connect connection is the simplest type of connection, which is achieved by connecting two switches together with a single Ethernet cable. A cross-over connection is more complex and requires two Ethernet cables, one connecting the first switch to the second switch, and the second connecting the second switch to the third switch.

Once the type of connection has been determined, the IT admin can begin the process of connecting the switches. The first step is to connect the Ethernet cable between the first and second switch. To do this, each switch must have an Ethernet port configured to accept the connection. The ports must be set to the same speed, duplex, and VLAN. Additionally, the switches must be on the same subnet to successfully communicate with each other.

Once the connection between the first and second switch is established, the IT admin must then create a second Ethernet connection between the second and third switch. This connection is different from the first connection in that it is a cross-over connection, which requires two Ethernet cables. To create this connection, the IT admin must configure the ports on the second and third switch to the same speed, duplex, and VLAN. Additionally, the switches must be on the same subnet to successfully communicate with each other.

Once the connections between the switches are established, the IT admin can then configure the switches for communication. To do this, the IT admin must ensure that the ports on the switches are set to the same VLAN. Additionally, the IT admin must enable trunking between the switches by configuring the ports on the switches to accept traffic from multiple VLANs. Once this is done, the IT admin must then enable routing between the switches by configuring the IP addresses on the switches.

Connecting three Cisco switches via Ethernet ports can be a tricky task, but with a basic understanding of networking and the different types of Ethernet connections, it can be accomplished successfully. The IT admin must ensure that the ports on the switches are set to the same speed, duplex, and VLAN, and that the switches are on the same subnet. Additionally, the IT admin must enable trunking and routing between the switches. If these steps are followed correctly, the IT admin should have no problem connecting the switches via Ethernet ports.
