What is Ethernet Frame? An Ethernet frame is a data link layer protocol data unit and uses the underlying network topology of MAC addresses for communication between nodes on a network segment. An Ethernet frame consists of two parts: an Ethernet header, followed by an Ethernet payload. The header contains destination and source MAC addresses, … Read more
Understanding the differences between VLANs (Virtual Local Area Networks) and subnets is crucial for anyone working in network administration or engineering. While both are important tools for segmenting networks, they operate on different layers and serve different purposes. This post will provide an in-depth explanation of what VLANs and subnets are, their key advantages when … Read more
We are discussing a very interesting topic of switching i.e. VTP (VLAN Trunking Protocol). Through this blog, you can understand VTP and the role of VTP in switching. In this blog, we have discussed all things about VTP and its work function. VTP- VLAN Trunking Protocol: VTP (VLAN Trunking Protocol) has three modes: 1. Server … Read more
VLAN vs VRF A virtual local area network (VLAN) is a logical grouping of network devices that share a common communication path but are isolated from each other at the data link layer (OSI Layer 2). A VLAN allows multiple physically separate networks to communicate as if they were attached to the same wire, even … Read more
What is EtherChannel? EtherChannel is a port link aggregation technology used primarily on Cisco switches. It allows the grouping of several physical Ethernet links to create one logical channel that provides a bandwidth of up to 4 Gigabits per second (Gbps). EtherChannel has been available on Cisco Catalyst switches since the introduction of the Cisco … Read more
