Description
Wireless Security Features
The C881WD-E-K9 Cisco 881WD is a wireless router that supports IEEE 802.11n and has 4 Fast Ethernet ports and 1 broadband port. It has several built-in wireless security features to protect your network and data from unauthorized access and attacks. Some of these features include:
- Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2): These standards provide strong data encryption and access control for wireless networks. They use Advanced Encryption Standard (AES) to encrypt wireless data and prevent unauthorized access.
- Cisco Wireless Security Suite: This suite includes a set of security features such as Wireless Intrusion Prevention System (WIPS), Wireless Control System (WCS), and Identity Services Engine (ISE) to provide comprehensive wireless security.
- Virtual Private Network (VPN) support: This feature allows employees, partners, and vendors to securely access corporate resources remotely.
- Network Admission Control (NAC): NAC ensures that devices connecting to the network comply with security policies before granting access.
- Advanced Encryption Standard (AES): AES is a widely accepted and implemented standard for encrypting sensitive data, it provides an extra layer of security for the wireless network.
- Wireless Client Steering: This feature allows to steer wireless clients to the optimal access point based on signal strength, client capabilities and other factors, it improves the performance and security of the wireless network.
- Firewall and Intrusion Prevention: The router comes with a built-in firewall that can be configured to block unwanted traffic and protect against cyber threats, it also comes with intrusion prevention system (IPS) to detect and prevent network attacks.
-Guest Access: Create a separate, secure network for guests with restricted access to the corporate network.
- Quality of Service (QoS): Prioritize network traffic for different types of applications and services to ensure that critical traffic receives the bandwidth it needs.
Routing Protocols and Configuration
Routing protocols are used by routers to determine the best path for data to travel from one network to another. Different routing protocols have different characteristics and are suited for different types of networks. The Cisco C881WD-E-K9 supports several routing protocols, including:
- Static routing: In this method, the administrator manually configures the routing table with specific routes. This method is suitable for small networks with few routes and is easy to configure.
- Routing Information Protocol (RIP): This is a distance-vector routing protocol that uses hop count as a metric to determine the best path. RIP is a simple and widely supported protocol, but it can’t handle large networks.
- Open Shortest Path First (OSPF): This is a link state routing protocol that uses a more complex metric, the shortest path first, to determine the best path. OSPF is a more advanced protocol, but it requires more configuration and is better suited for larger networks.
- Border Gateway Protocol (BGP): This is a path vector routing protocol that is used to connect different autonomous systems (AS) together. BGP is typically used in service provider networks to exchange routing information between different AS.
In terms of wireless configuration, the Cisco 881WD-E-K9 supports IEEE 802.11n standard and operates in the 2.4GHz ISM band. The wireless router can be configured to operate as an Access Point, Wireless Distribution System (WDS), or Wireless Client. The router can also be configured to use various security protocols such as WPA2-Enterprise, WPA2-Personal, WPA-Enterprise, WPA-Personal, and WEP. The specific configuration will depend on the network setup and requirements. It is recommended to consult the Cisco 881WD Configuration Guide for detailed instructions on configuring the router.
Network Management and Monitoring
The Cisco C881WD-E-K9 wireless router can be managed and monitored using various tools and methods. Some of the most common include:
- Cisco Network Assistant (CNA): This is a free software tool that can be used to discover, configure, and troubleshoot Cisco devices on a network. CNA can be used to manage multiple Cisco 881WD-E-K9 routers from a single console, making it a convenient tool for network administrators.
- Command Line Interface (CLI): The router can be configured and managed using the command-line interface (CLI) via a console or Telnet/SSH connection. This method requires knowledge of Cisco IOS commands and can be more time-consuming than using a graphical interface like CNA.
- Web Interface: The router can also be configured and managed through a web interface, which can be accessed by a web browser. This method is easy to use, but it requires a device to be connected to the router’s network.
- SNMP: The router supports Simple Network Management Protocol (SNMP) which allows to collect and monitor the device’s performance and status. By using SNMP, the administrator can monitor the router’s CPU usage, memory usage, and interface statistics.
- Syslog: The router can be configured to send syslog messages to a syslog server, which can be used to monitor the router’s activity and troubleshoot issues.
- Network Management Systems (NMS): The router can be integrated with a network management system (NMS) to provide centralized monitoring and management of multiple devices on a network.
