SSID – Service Set Identifier (Network Name)
Acts as a password to connect Basic Security (Easily Cracked) Encryption – WEP 40 bit and 128bit encryption to “scramble” data Good security for small businesses Not enough security in sensitive environments Authentication with per user/per session WEP Extensible Authentication Protocol (EAP) open standard that promotes interoperability among the wireless client adapters and dial-in servers of various manufacturers. Lightweight EAP (LEAP)- Cisco Proprietary |

|
|
Wireless Encryption - What are WEP and WPA
|
WEP - Wired Equivalency Privacy
Good security for small businesses used to “scramble” data Not enough security in sensitive environments WPA - WiFi Protected Access (More Business Appropriate) WPA is the current industry-agreed requirement for secured wireless 802.11 communications It comprises 802.1X and EAP based access control and communications confidentiality based on TKIP data encryption |

|
1100 series Access-Points (802.11A/B/G or B/G)
Integrated Omni-directional antennas Can be either IOS (Standalone) or Lightweight (LAP) Indoor only |
|
|
1200 Series access points benefits
|
1200 series Access-points (802.11A/B/G or B/G)
Removable Antennas (must be added to quote though) Can be either IOS or LAP based (requires WLC) Rugged Metal Case – Extended Operating Temperature |

Breakdown of Cisco wireless solutions. Access point/bridge ect family
|
1100 series Access-Points (802.11A,B,G or B,G)
1200 series Access-points (802.11A,B,G or B,G) Client Adapters PCMCIA and PCI 1400 Series Bridges (outdoor) Based on the 802.11a standard and are ideal for wireless backhaul, connecting multiple LANs in a campus or metropolitan environment. 1300 Series Bridge (indoor or outdoor) An Access Point A Bridge A Workgroup Bridge |
|
|
Can the 1100 and 1200 series access points be used as Authentication server in smaller networks.
|
Yes
|
|
|
Wireless LAN Controllers (WLC)
|
Used for centralized management of lightweight wireless network
Advanced Radio Management features Ability to self heal Remediation of Rogue Access Points Ability to do location tracking with WCS Supports 802.11n draft standard 2.0 |
|
|
Wireless Control System (WCS)
|
Ability to manage multiple WLC from single management console
Import blue prints for better diagnostics of wireless coverage With location tracking features, can track Active RFID tags such AeroScout or Pango With the Cisco Wireless Location Appliance, 2500 devices, including wireless clients or Wi-Fi tags, can be tracked simultaneously |
|
|
Wireless LAN Solution Engine:
|
For Managing Autonomous AP’s
Components are WLSE and WLSE Express |
|
|
WLSE
|
WLSE is a centralized solution for managing Cisco IOS-based (Standalone) APs
Auto-configuration of new AP’s Configuration roll out and archive Radio frequency (RF) Monitoring Assisted Site Survey Automated channel selection and power management Detects unauthorized WLAN components, such as rogue access points and ad-hoc networks. |
|
|
WLSE Express
|
Step down from the WLSE which is a centralized solution for managing Cisco IOS-based (Standalone) APs
WLSE Express is for Small to medium office solution for up to 100 AP’s (with upgrade lics) |
|
|
WAN
|
Wide Area Network
Covers a geographical area that is larger than a LAN, and can span states, provinces, countries, or even the world Centralized WAN (Hub & Spoke) vs. Distributed WAN WAN Designs Leased Lines Costly – Don’t Scale Frame-Relay Flexible Cost Effective ATM |
|
|
Distributed WAN
|
Distributed WAN also known as Enterprise WAN. If you have servers at each location, this is Distributed WAN.
|
|
|
WAN Designs: 3 types
|
Leased Lines
Costly – Don’t Scale Frame-Relay Flexible Cost Effective ATM Leased Lines are costly. Frame Relay, more cost effective. ATM popular for Voice and Video because of built in QoS. |
|
|
WAN:
Explain Backbone and Edge |
Backbone
Handles the major traffic Employs highest speed transmission paths in network Runs longest distance Smaller networks are attached to the Backbone Edge- Part of network located on the periphery Connective devices between component networks. |
|
|
Product Components of a WAN:
|
Just distinguish these components. This is more from a Service Provider network point of view.
Routers (Edge and Backbone) Optimal path network traffic is to forwarded WAN Switch (ISP Backbone) High End Frame-Relay Switch ATM switch Access Server Network Entry and Exit point Concentration Point for dial-in / dial-out connections Gateway Network Entry and Exit point Protocol Converter for different types of networks Go-between for same protocol networks |

differentiate between the 10000 and the 12000 7600 and CRS-1 (Cisco Edge Routers)
|
10000 Series supports Frame Relay, ATM, and leased lines in a single platform, allowing customers to provide multiple types of services (including IP/MPLS) to end users without having to maintain multiple edge devices
12000 series- premier backbone and edge support DS3 for Frame Relay 7600 series- high-performance IP/Multiprotocol Label Switching (MPLS) features for service provider edge applications CRS-1 – World Class Carrier Routing Platform for ISP Backbone |
