Description
Network Management and Monitoring
The Cisco 2911 router is a modular router that supports various network management and monitoring features. These features include:
- Cisco IOS Software: The router runs on Cisco IOS software, which provides a command-line interface (CLI) and a web-based interface (GUI) for managing and monitoring the router. The CLI allows administrators to configure and control the router using a command-line interface, while the GUI provides a web-based interface that allows administrators to manage and monitor the router through a web browser.
- SNMP: The router supports Simple Network Management Protocol (SNMP) for monitoring the router’s performance and status. This allows administrators to monitor the router’s CPU and memory usage, interface status, and other performance metrics using a network management system (NMS) that supports SNMP.
- Syslog: The router can send system messages, such as error messages and debugging information, to a syslog server for logging and analysis. This allows administrators to view system messages and troubleshoot issues with the router.
- NetFlow: The router supports Cisco NetFlow, which allows for the collection and analysis of network traffic data. This allows administrators to monitor network traffic patterns and identify potential bottlenecks or security issues.
- Remote management: The router can be remotely managed and monitored using SSH, Telnet, and other remote management protocols. This allows administrators to access the router’s CLI and GUI remotely, and make changes to the router’s configuration.
- CiscoWorks: The router is also supported by CiscoWorks, a network management software that provides a centralized management and monitoring solution for Cisco devices. This allows administrators to manage and monitor multiple Cisco devices from a single interface.
- SD-WAN: The router also support SD-WAN solution for WAN management. This solution provides a centralized management of the WAN infrastructure, and allows administrators to monitor and configure the network traffic patterns to improve the network performance and reduce costs.
Routing Protocols and Configuration
Routing protocols are used to exchange routing information between routers in a network. They determine the best path for data to travel from one network to another, and update the routing table with the most efficient routes. Cisco 2911 routers support a variety of Interior Gateway Protocols (IGPs) and Exterior Gateway Protocols (EGPs) that can be configured to route data in a network.
Interior Gateway Protocols (IGPs) are routing protocols that are used within an autonomous system (AS), which is a group of routers under a common administrative domain. Cisco 2911 routers support the following IGPs:
- Routing Information Protocol (RIP) – a distance-vector protocol that uses hop count as a metric to determine the best path to a destination.
- Enhanced Interior Gateway Routing Protocol (EIGRP) – a Cisco proprietary protocol that uses a combination of metrics, such as bandwidth and delay, to determine the best path to a destination.
- Open Shortest Path First (OSPF) – a link-state protocol that uses the shortest path to a destination based on the cost of the link.
Exterior Gateway Protocols (EGPs) are routing protocols that are used to exchange routing information between autonomous systems. Cisco 2911 routers support the following EGP:
- Border Gateway Protocol (BGP) – a path-vector protocol that is used to exchange routing information between different autonomous systems on the Internet.
The configuration of routing protocols on a Cisco 2911 router involves several steps:
- Configuring the router’s interfaces with IP addresses and enabling them using the “interface” and “ip address” commands.
- Configuring the routing protocol on the router using the appropriate commands for the protocol. For example, the “router rip” command is used to enable RIP on a Cisco 2911 router.
- Configuring any necessary parameters such as network addresses and authentication using the appropriate commands for the protocol.
- Verifying the configuration and checking for any errors using the “show running-config” and “debug” commands.
- Testing connectivity to other routers in the network using the “ping” and “traceroute” commands.
Quality of Service (QoS) Capabilities
The C2911-AX/K9 Cisco Systems 2911 router has several Quality of Service (QoS) capabilities that can be configured to prioritize and manage network traffic. Some of the main QoS features of the Cisco 2911 router include:
- Class-Based Weighted Fair Queuing (CBWFQ) – allows for the allocation of bandwidth to specific traffic classes based on their configured weight, ensuring that high-priority traffic gets the bandwidth it needs.
- Low Latency Queuing (LLQ) – allows for the prioritization of delay-sensitive traffic, such as voice and video, to minimize delay and jitter.
- Weighted Random Early Detection (WRED) – helps to prevent network congestion by randomly dropping packets that belong to a lower-priority traffic class when the queue becomes full.
- Traffic Shaping and Policing – allows for the control of the rate at which traffic is sent into a network, helping to prevent network congestion and ensuring that bandwidth is used efficiently.
- Multi-Layer Protocol Label Switching (MPLS) – allows for the creation of virtual private networks (VPNs) and the prioritization of specific traffic flows based on their labels.
To configure QoS on a Cisco 2911 router, you can use the command-line interface (CLI) through the console or a remote connection. The basic steps to configure QoS on a Cisco 2911 router include:
- Identifying the types of traffic that need to be prioritized and creating class maps to match them.
- Configuring policies to assign a priority level to each class of traffic.
- Applying the policies to the appropriate interfaces.
- Verifying the configuration and checking for any errors.
