Description
Network Management Systems
The Cisco 2911 Integrated Services Router (ISR) is a modular router that supports various network management systems and protocols, including:
- Cisco IOS Software: This is the underlying operating system of the router, providing device management and configuration capabilities through a command-line interface (CLI) or a web-based graphical user interface (GUI).
- Cisco Configuration Professional (CCP): A GUI-based tool that allows administrators to configure and manage Cisco devices, including the 2911 router. It provides a visual representation of the network, making it easy to navigate and configure different components.
- Cisco Network Assistant (CNA): A centralized management tool that allows administrators to manage multiple Cisco devices, including the 2911 router, from a single console. CNA provides a simple, intuitive interface that makes it easy to perform common network management tasks.
- Cisco Security Manager (CSM): A security management system that allows administrators to configure and manage security features on the 2911 router, such as firewall and VPN settings.
- Cisco Prime Infrastructure (PI): A comprehensive network management system that allows administrators to monitor, troubleshoot, and manage Cisco devices, including the 2911 router. PI provides a unified view of the network and allows administrators to perform tasks such as software upgrades, configuration management, and monitoring.
- SNMP: Simple Network Management Protocol is an industry standard protocol for managing and monitoring network devices, including the 2911 router. SNMP allows administrators to gather information about the router’s performance, status, and configuration using third-party network management systems.
The C2911-VSEC-SRE/K9 model also includes a feature called Virtual Security Gateway (VSG) that allows the creation of multiple virtual routers with security features like VPN, firewall and intrusion prevention. Additionally, it supports other protocols like HSRP, VRRP, GLBP, and NHRP for providing redundancy and failover mechanisms in the network.
Performance and Scalability
The Cisco 2911 Integrated Services Router (ISR) is a modular router that offers performance and scalability features to support growing networks. Some of the performance and scalability features of the C2911-VSEC-SRE/K9 model include:
- Hardware-accelerated VPN: The router is equipped with an integrated VPN accelerator card that provides hardware-based encryption and decryption capabilities, significantly increasing VPN performance.
- High-performance routing: The router supports advanced routing protocols, such as Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF), and can handle up to 1 million routes. This allows the router to scale to handle large and complex networks.
- Memory and storage: The C2911-VSEC-SRE/K9 model has 2 GB of DRAM and 4 GB of flash memory, allowing it to handle large configurations and store routing and security information.
- Interface and slot expansion: The router has 3 integrated ports and 10 expansion slots that can be used to add additional interfaces, such as Ethernet, serial, and T1/E1, as well as other modules, such as security and voice.
- Virtual Security Gateway (VSG) feature: This feature allows the creation of multiple virtual routers with security features like VPN, firewall and intrusion prevention, which helps to increase the scalability and security of the network.
- Redundancy and failover mechanisms: The router supports HSRP, VRRP, GLBP, and NHRP which allows to provide redundancy and failover mechanisms in the network.
- Power Supply: The router is capable of supporting both AC and DC power supply.
Quality of Service (QoS) Capabilities
The Cisco 2911 C2911-VSEC-SRE/K9 is an integrated services router that offers advanced Quality of Service (QoS) capabilities to help manage and prioritize network traffic.
One of the key QoS features of this router is Class-Based Weighted Fair Queuing (CBWFQ). This feature allows you to classify and mark different types of traffic, and assign different priority levels to each class of traffic. This ensures that mission-critical traffic, such as VoIP or video conferencing, is given priority over less important traffic, such as file transfers or web browsing.
Another QoS feature of this router is Low Latency Queuing (LLQ). This feature ensures that delay-sensitive traffic, such as VoIP or video conferencing, is given priority over other types of traffic. This helps to reduce jitter and packet loss, which can have a significant impact on the quality of real-time applications.
Policy-Based Routing (PBR) is another feature that allows you to route traffic based on specific policies, giving you more control over how traffic is handled in your network. Weighted Random Early Detection (WRED) is a congestion management feature that helps to prevent network congestion by randomly dropping lower-priority traffic when the network becomes overloaded.
These QoS capabilities of the Cisco 2911 C2911-VSEC-SRE/K9 allow you to prioritize mission-critical traffic, improve network efficiency and ensure that the available bandwidth is used effectively.
