IP Address Class B Subnetting- Explained with Examples.

How to Subnet Class B Addresses. Subnetting a Class B network is very similar to subnetting a Class C network, with the only difference being that when subnetting a Class B network, you will be focusing on the third octet, whereas in Class C, you will be working on the fourth octet. Take a look at this: To… Read More »

Switchport Trunk Explained with Example.

How to Configure a Trunk Port on a Cisco Switch. Switchport trunk in computer networking refers to a specific configuration on a switch port that allows it to carry traffic for multiple VLANs (Virtual Local Area Networks). This is in contrast to an “access port,” which typically carries traffic for a single VLAN. Let’s explore the concept in… Read More »
