DHCP stands for Dynamic Host Configuration Protocol, used to automatically assign IP addresses to devices on a network.
DHCP eliminates the need for manual IP address configuration
It assigns IP addresses, subnet masks, default gateways, and DNS servers to devices
DHCP operates on the client-server model
Example: When a device connects to a network, it sends a DHCP request to obtain an IP address
DNS is a system that translates domain names to IP addresses, allowing users to access websites using human-readable names.
DNS stands for Domain Name System
It is a protocol used to translate domain names to IP addresses
DNS servers store a database of domain names and their corresponding IP addresses
DNS helps users access websites using easy-to-remember domain names instead of complex IP addresses
Examples of DNS servers...

STP (Spanning Tree Protocol) is used to prevent loops in a network by blocking redundant paths between switches.
STP elects a root bridge to serve as the central point in the network
Each switch determines the best path to the root bridge based on the lowest path cost
Ports on switches are designated as root ports, designated ports, or blocking ports to create a loop-free topology

BGP routing tables store information about routes to different networks and the best path to reach them.
BGP uses a path-vector routing protocol to determine the best path for a packet to reach its destination.
BGP routing tables contain information about the network prefixes, the next hop to reach them, and the path attributes that determine the best path.
BGP routers exchange routing information with their neighbors to ...
NAT is a technique used to map private IP addresses to public IP addresses. Port numbers are used to identify specific applications.
NAT stands for Network Address Translation
It is used to allow devices with private IP addresses to access the internet using a public IP address
Port numbers are used to identify specific applications or services
Common port numbers include 80 for HTTP, 443 for HTTPS, and 22 for SSH
Default single port range when neither port range in source NAT pools nor default port range are configured.
When neither port range in source NAT pools nor default port range are configured, the default single port range is 1024 through 63,487.
This range is used for outbound traffic initiated by the device.
It is important to configure the port range to avoid conflicts with other devices on the network.
For example, if m...
MSS in TCP refers to the maximum segment size, which is the largest amount of data that can be sent in a single TCP segment.
MSS is negotiated during the TCP three-way handshake
It is determined by the maximum transmission unit (MTU) of the network
MSS can be adjusted by the sender or receiver using TCP options
A smaller MSS can help prevent fragmentation and improve network performance
Packet drops can be caused by various factors. Troubleshooting involves identifying the root cause and implementing a solution.
Check for network congestion or bandwidth limitations
Verify if the packet is being dropped at the source or destination
Inspect network devices for errors or misconfigurations
Use packet capture tools to analyze the traffic
Consider implementing Quality of Service (QoS) policies
Update firmware or
To check port and duplex setting, MSS and MTU, and link utilization in network engineering.
Use command 'show interface' to check port and duplex setting.
Use command 'ping -f -l
Use command 'netstat -s' to check MSS.
Use command 'show interface' or 'show interfaces utilization' to check link utilization.
