As always, the most basic part is to configure the username and password for your switch, and understand how it works, have a look of show run, you will understand it is basically like a linux etc. preconfigured settings. for people who has linux and network experience, it is not hard to pick  up.

There are terms we need understand, and that is all.


So of crouse we need understand how ports are configured/customized especially if you are not the one who configure it, before change it, we need go through something for sure.

” Understanding Switch Clusters”

“A switch cluster is a set of up to 16 connected, cluster-capable Catalyst switches that are managed as a
single entity. The switches in the cluster use the switch clustering technology so that you can configure
and troubleshoot a group of different Catalyst desktop switch platforms through a single IP address. “

Did you mass up something? I did. Now a roughly idea of Cluster is made, we look into it later.

“Understanding Stacks”

“A switch stack is a set of up to four Catalyst 2960-S switches connected through their stack ports. One
of the switches controls the operation of the stack and is called the stack master. The stack master and
the other switches in the stack are stack members. Layer 2 protocol presents the entire switch stack as a
single entity to the network.”

Well, this give you the idea of stack. So we don`t worry about it any more. Keep Going.

“Understanding Interface Types”
This section describes the different types of supported interfaces with references to chapters that contain
more detailed information about configuring these interfaces.
Note The stack ports on the rear of the switch are not Ethernet ports and cannot be configured.
• Port-Based VLANs
A VLAN is a switched network that is logically segmented by function, team, or application, without
regard to the physical location of the users. For more information about VLANs, see the Chapter 13,
“Configuring VLANs.” Packets received on a port are forwarded only to ports that belong to the same
VLAN as the receiving port. Network devices in different VLANs cannot communicate with one another
without a Layer 3 device to route traffic between the VLANs.
• Switch Ports

Switch ports are Layer 2-only interfaces associated with a physical port. Switch ports belong to one or
more VLANs. You use switch ports for managing the physical interface and associated Layer 2 protocols.
• Switch Virtual Interfaces
• EtherChannel Port Groups
• Dual-Purpose Uplink Ports
• Power over Ethernet Ports
• Connecting Interfaces
