The CISCO2821-DC Cisco 2821 Integrated Services Router is a multi-purpose router that includes 4-port Ethernet and serial interfaces.
The 4-port Ethernet interfaces allow for the connection of multiple wired devices to the router, such as computers, servers, and other network devices. These Ethernet ports can be configured for different types of network connections, such as fast Ethernet or gigabit Ethernet, to support different speeds and bandwidth requirements.
The serial interfaces on the Cisco 2821 router are used for connecting to other network devices through a serial connection. These interfaces can be used to connect to other routers, switches, or other network devices using a serial cable. They can also be used to connect to leased lines, Frame Relay networks, or other WAN (Wide Area Network) connections.
The Cisco 2821 router also supports advanced security features and Quality of Service (QoS) to provide a secure and reliable network connection. This makes it a suitable option for small to medium-sized businesses, branch offices, and other enterprise environments.
Cisco IOS Software and security featuresThe CISCO2821-DC Cisco 2821 Integrated Services Router is a high-performance router that runs on Cisco IOS Software. Cisco IOS (Internetwork Operating System) software provides the features and functionality required for network routing, switching, and security. It allows the router to support various routing protocols, such as OSPF and BGP, and provides advanced security features to protect the network.
Some of the security features available on the CISCO2821-DC router include:
- Firewall: The router includes a built-in firewall that can be used to filter incoming and outgoing traffic based on various criteria, such as IP address, port, and protocol.
- VPN: The router supports Virtual Private Network (VPN) connections, allowing remote users to securely access the network.
- IPS: The router includes an Intrusion Prevention System (IPS) that can detect and prevent cyber attacks in real-time.
- AAA: The router supports Authentication, Authorization, and Accounting (AAA) for secure access control.
- Encryption: The router supports various encryption protocols, such as IPSec and SSL, to secure data transmissions.
- Network Admission Control (NAC): NAC is a security solution that allows to ensure that endpoint devices comply with security policies before they can access the network.
These security features, along with the robustness and reliability of the Cisco IOS software, make the CISCO2821-DC Cisco 2821 Integrated Services Router a great choice for businesses and organizations looking to secure their networks and protect against cyber threats.
Quality of Service (QoS) capabilitiesThe CISCO2821-DC Cisco 2821 Integrated Services Router has Quality of Service (QoS) capabilities to help ensure that mission-critical traffic is handled with a higher priority than less important traffic. QoS is a set of techniques used to manage and prioritize network traffic to ensure that the most important traffic gets delivered first and with the best quality.
The Cisco 2821 router supports several QoS features, including:
- Class-Based Weighted Fair Queuing (CBWFQ): This feature allows you to divide network traffic into different classes and assign different priorities to each class.
- Low Latency Queuing (LLQ): This feature allows you to assign priority to certain types of traffic, such as voice or video, to ensure that they are delivered with minimal delay.
- Traffic Shaping and Policing: These features allow you to control the rate at which traffic is sent and received, ensuring that the network does not become overloaded.
- Voice and Video Quality of Service (QoS): The Cisco 2821 router supports QoS features specifically designed for voice and video traffic, such as call admission control, bandwidth reservation, and packet marking.
