CISCO CCNA 200-301 Part2 100% LABS.

Download and install Cisco Packet Tracer, register for free, log in, and prepare to use version 8.22 for DHCP lab simulations.

Explore how hubs and switches differ, including collision domains, bandwidth sharing, and VLAN-based broadcast domains, and see how multilayer switches add routing with per-port configuration.

Compare switches and multilayer switches, enable IP routing on a switch, and evaluate PoE, port speeds, and lab setups with phones and access points.

Explore the fundamentals of tcp/ip classes and ip addressing, including the difference between ip and tcp, ipv4 vs ipv6, and constructing 32-bit addresses from four decimal octets with binary conversion.

Identify class a, b, and c by the first octet (1–127, 128–191, 192–223) and apply their default subnet masks: 255.0.0.0, 255.255.0.0, 255.255.255.0.

Explore class C addresses, range 192 to 223, with default subnet mask 255.255.255.0. Identify network portion as the first three octets and host portion as the last, with 254 hosts.

Explore class B addressing: the first two octets form the network, the last two the host, with a /16 subnet mask 255.255.0.0 and up to 65,534 hosts per network.

Explore class a addressing: first octet is network, last three are hosts, using 10.0.0.0/8 with 255.0.0.0, first host 10.0.0.1, and class a, b, c internal use.

Explore Class D multicast and Class E research designations, noting their uses for pay-per-view and government projects, and connect these concepts to multicast routing in CCNA.

Learn to subnet a class C network, converting from classful to classless with a /27 for eight subnets, giving 30 hosts per subnet and identifying networks, hosts, and broadcasts.

Demonstrates subnetting a class C network by borrowing four bits to yield 16 networks with a /28 mask, providing 14 hosts per network, and detailing network ID, first/last host, broadcast.

Learn to reverse engineer a class c subnet by analyzing a slash mask and borrowed bits. See how to determine networks, hosts and broadcast using practical examples.

Explains class B subnetting by borrowing bits from the third octet to create slash 21 and slash 23 networks, calculating network IDs, hosts per subnet, and broadcast addresses.

Explore subnetting a class B network by borrowing bits to create 1024 subnets with 62 hosts each, and verify network IDs and broadcasts using Packet Tracer.

Mo demonstrates reverse engineering a class B subnet using slash notations, calculating network ID, first and last host, and broadcast with correct masks, then applies practice to VLAN-oriented topology.

Demonstrate how lack of port security allows devices to auto-assign ip addresses via dhcp, connect to servers, and access resources, highlighting why mac-based port security is essential.

Configure port security on access ports with sticky or manual MAC addresses, and set a maximum with aging. Monitor violations and recover a violated port using shutdown and no shutdown.

Learn to enforce port security across multiple switch ports by enabling switchport mode access, applying sticky mac addresses with interface range commands, and verifying with show port security.

Configure switch port security on interface f0/3 with sticky MAC addresses, set maximum MAC addresses to two, and observe violation shut down behavior using show port security.

Learn how port security handles violations on switches, comparing default shut down with protect and restrict modes, using sticky Mac addresses, and noting that restrict reports while protect does not.

Learn how port security makes mac address table entries static on switches, and why switches filter by mac addresses while routers filter by IP within VLAN contexts.

Establish a switch console connection with a rollover cable and putty, configure line console 0 and enable secret, encrypt passwords, and prepare for remote access via telnet or ssh.

Configure telnet access to a switch by setting up VLAN 1 IP, enabling VTY lines 0–2 with a login password, and noting the security risks of telnet; SSH comes next.

Configure usernames and local login on switch console and vty, create admin one and admin two with level 15, and enable login local.

Configure the vty lines to allow only ssh access, enable ssh version 2, set usernames and secrets, and restrict transport input to ssh for secure remote switch login.

Configure a banner on a Cisco switch via global configuration, using the banner MOTD command with a delimiter to display a warning message for authorized users.

Learn how switches use VLANs to create multiple broadcast domains, limit collision domains, and improve security by separating laptops, servers, printers, and phones across different subnets.

Explore how to create and assign vlans (10, 20, 30), configure access ports, separate broadcast domains on switches, and plan static ip networks to illustrate vlan isolation.

Explore vlan across switches by configuring two switches with vlan 10 and vlan 20, assigning ports, and enabling trunking (802.1q) to allow inter-switch communication while vlan 1 default remains local.

Develop and test vlan 30 across switches by creating vlan 30, assigning ports 6–7 to it, and using trunks to permit all vlans except 20.

Configure switches with vlans and trunking. Assign access ports to vlan ten and vlan twenty, define the native vlan, and prepare for inter vlan routing.

Learn inter vlan routing with a router on a stick to connect vlan ten, vlan twenty, and vlan thirty. Implement trunking and subinterfaces with a default gateway.

Set up a router as a dhcp server for multiple vlans (router on a stick), creating dhcp pools for vlan ten, twenty, and thirty, with excluded addresses.

Configure inter-VLAN routing with a router-on-a-stick across VLANs 10, 20, and 30 by setting up switches, trunks, and DHCP addressing, then verify with ping and traceroute.

Learn to perform inter vlan routing with a multilayer switch by creating vlans, configuring switch virtual interfaces, assigning IP addresses, and enabling IP routing.

This lecture demonstrates configuring a multi-layer switch as a dhcp server, creating dhcp pools for vlans 10, 20, and 30 with networks and gateways, preparing for vtep vlan trunking.

Set up udemy.edu vtp domain and password to synchronize vlan creation across switches in server mode. Observe that vtp propagates vlan but not port configurations, and client mode forbids edits.

Explore configuring VTP on two switches, establishing a trunk, setting a VTP domain and server/client modes, and synchronizing VLANs 10, 20, and 30 through replication.

Learn to configure vtp types (server, client, transparent) across a four-switch topology, trunk ports, and vlan creation, with domain Udemy and vlan synchronization behavior.
