Network

1. Wired Network (Switching)

2. A switch is a network device with multiple interfaces or ports. The ports can connect computers and
other devices, and any devices that are connected to the switch can communicate with each other.
Switches use all three, broadcast, multicast, and unicast, but they are primarily known for their efficient handling of
unicast and multicast traffic.
Types of Switches
1. Unmanaged Switch
1. Basic plug-and-play device.
2. No configuration required.
3. Best for small/home networks.
2. Managed Switch (Layer2 & Layer3)
1. Provides configuration via CLI/Web/Software.
2. Supports VLANs, QoS, SNMP, STP, security features.
3. Used in enterprise/campus networks.
3. Layer 2 Switch (PoE & Non-POE, Stackable, Gig-MultiGig)
1. Operates at the Data Link Layer (MAC address).
2. Forwards frames within the same network.
3. Common in LANs.
4. Layer 3 Switch (Multilayer Switch)
1. Operates at both Layer 2 & 3.
2. Supports routing (IP-based decisions).
3. Used for inter-VLAN routing and large networks.

3. Switch Functions:
1. L3 Switch ( CoreDistribution Switch):
 Routing Protocols support
 Inter-VLAN Routing
 Access Control Lists (ACLs)
 Quality of Service (QoS)
 DHCP Operations (Lease & MAC Binding)
 All L2 Features
2. L2 Switch (PoE & Non-POE, Stackable, Gig-Multi-Gig):
 Mac Table
 Broadcast & Multicast Handling
 VLAN Support
 Port-Based Segmentation

7. Before Configuration & Hardening Guidelines
Before Reaching Installation Site:
 BOQ Verification & Understanding
 Solution document, Finalized Scope & HLD Review
 Tools Preparation (Console Cable, Mounting Hardware, terminal emulator…etc)
 Checklist Preparation as per Customer Use Case & Approval (IP Schema, Hostname, User
Logins, SNMP, NTP, Syslog, MFA details …etc)
At Installation Site:
 Material Verification as per BOQ
 Installation site readiness (Rack space, Power & cooling availability ..etc
 Device Power on & Physical verification
 Verify all Devices with latest firmware
Hardening Practices (Depends on Customer Use Case)
 Disable Telnet, use only SSH
 Enabling strong & encrypted login user password
 Enable port security (MAC address limiting)
 Restrict management access (ACLs, mgmt VLAN)
 Use AAA (TACACS+/RADIUS) for centralized authentication

8. Wireless Network

9. Wireless Access Point (WAP) acts as a bridge between wireless clients and the LAN
(switch/router).
Scanning
The user device (laptop/phone) scans for available Wi-Fi networks (SSIDs) by sending probe requests.
Access Points (APs) respond with beacons advertising their SSIDs.
Authentication
The user chooses a Wi-Fi network (SSID).
Depending on security type:
Open Authentication → No password required.
WPA2/WPA3-PSK → User enters a password (pre-shared key).
Enterprise Wi-Fi (WPA2/WPA3-Enterprise) → User authenticates via RADIUS/802.1X
(username/password, certificate, etc.).
Association
Once authentication succeeds, the client sends an association request to the AP.
AP responds with association response, completing the wireless link.
IP Address Assignment
The device requests an IP address (usually via DHCP).
DHCP server (often integrated with the switch, router, or AP) assigns an IP address, gateway, and DNS.
Data Transmission
User device is now part of the LAN/WLAN.

Wireless Frequency & Channels
2.4 GHz → Longer range, penetrates walls, but lower speed : Only 3 non-overlapping channels
5 GHz → Higher speed, less interference, but shorter range : Provides 25+ usable Wi-Fi channels (channel width)
6 GHz (Wi-Fi 6E/7) → Even faster, huge channel capacity, but shortest range.
Global Standardization
•IEEE (Wi-Fi Alliance) standardized Wi-Fi to operate in these bands for compatibility across devices.
