What is the Spanning Tree Protocol (STP)? STP is used by switches to prevent loops from occurring on a network, this process is implemented by using the spanning tree algorithm to disable unwanted links and blocking ports that could cause a loop. Here are the key points about STP: Purpose: In a network with multiple paths between switches,… Read More »
Understanding IP Addresses. An IP address is uniquely used to identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask. The 32 binary bits are broken into four octets (1 octet = 8 bits). Each… Read More »

How to Configure Switch Port The Switchport ACL (PACL) feature provides the ability to perform access control on specific Layer 2 ports. ACLs can also be used to control traffic on VLANs. Switch port ACLs can only be applied to Layer 2 interfaces in the inbound direction, and this controls traffic via IP access Lists. Switch port ACL application… Read More »
What is Switchport Security? Switchport security is a feature used in network switches, particularly in Cisco devices, to provide a layer of security at the switch port level. This feature helps in preventing unauthorized access to the network by controlling which devices are allowed to connect to each switch port. It is particularly relevant in environments where network… Read More »
