What Is Router-on-a-Stick Inter-VLANs Sub-interfaces? Router-on-a-Stick Inter-VLANs is a network setup that enhances communication between various VLANs on a single network device. It Involves connecting a single physical interface of a router to a switch, along with configuring multiple logical sub-interfaces on the router. This setup allows for the routing of traffic between different VLANs without the need… Read More »
What Is an Access Control List? Access Control Lists (ACLs) are filters that enable you to control which routing updates or packets are permitted or denied in or out of a network. They are specifically used by network administrators to filter traffic and provide extra security for their networks. This can be applied to routers (Cisco). ACLs provide… Read More »
By configuring EtherChannel, we bundle multiple physical connections between two or more Cisco switches into one logical link. This allows for increased bandwidth, improved fault tolerance, and load balancing across the aggregated links. EtherChannel also provides a more efficient use of available network resources and simplifies the management of network connections between switches. In a conventional network where… Read More »
What are the Types of STP? The Spanning Tree Protocol (STP) standards are a set of network protocols that ensure a loop-free topology for Ethernet networks.The basic idea behind STP is to prevent network disruptions caused by loops, which are common in Ethernet networks. STP works by organizing the network’s switches into a hierarchy and blocking certain redundant… Read More »
What Is IP Address Wildcards? An IP address wildcard is a method used in network configurations to specify a range of IP addresses. CIDR (Classless Inter-Domain Routing) is a method for allocating IP addresses and routing Internet Protocol packets. It was introduced in the early 1990s as a replacement for the traditional class-based IP addressing scheme, with the… Read More »
