Description
Management of Network Bandwidth
The Cisco 2911 C2911-VSEC-SRE/K9 “Cisco 2911 3 Ports 10 Slots Integrated Services Router” offers a variety of features to help you manage the bandwidth of your network. Some of the key features include:
- 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.
- 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.
- Traffic Shaping: This feature allows you to limit the amount of bandwidth that a specific type of traffic can consume, helping to ensure that there is enough bandwidth available for other types of traffic.
- Policy-Based Routing (PBR): This feature 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): This is a congestion management feature that helps to prevent network congestion by randomly dropping lower-priority traffic when the network becomes overloaded.
With these features, the Cisco 2911 C2911-VSEC-SRE/K9 allows you to effectively manage the bandwidth of your network and ensure that the available bandwidth is used efficiently and effectively.
Network Segmentation and Access Control
The Cisco 2911 C2911-VSEC-SRE/K9 “Cisco 2911 3 Ports 10 Slots Integrated Services Router” offers a variety of features to help you segment your network and control access to your network resources. Some of the key features include:
- VLANs: Virtual LANs (VLANs) allow you to segment your network into different logical networks, which can help improve network security and segmentation.
- Access Control Lists (ACLs): ACLs allow you to control access to network resources by defining rules that specify which types of traffic are allowed or denied.
- Identity-Based Networking (IBN): This feature allows you to segment the network based on the identity of the user, device or application, rather than the network’s IP address, it helps to ensure that only authorized users and devices have access to network resources.
- Cisco Identity Services Engine (ISE): This is a security solution that allows you to authenticate and authorize users and devices before granting them access to network resources.
- Cisco Firewall Services Module (FWSM): This is a firewall solution that allows you to create firewall rules to control access to network resources.
These features allow you to segment your network and control access to your network resources, which can help improve network security and reduce the risk of unauthorized access to your network.
High-Availability Features
The Cisco 2911 Integrated Services Router (ISR) with the VSEC-SRE/K9 license includes several high-availability features to ensure that the network remains up and running in case of hardware or software failures. Some of these features include:
- Redundant power supplies: The router can be configured with two power supplies, so that if one fails, the other can take over.
- Hot-swappable fans: The fans in the router can be replaced without shutting down the router.
- Dual Gigabit Ethernet ports: The router has two Gigabit Ethernet ports that can be configured for redundancy.
- VPN hardware acceleration: The router includes an integrated VPN accelerator card to offload VPN encryption and decryption tasks from the main CPU, which can help improve the router’s performance and availability.
- Stateful switchover (SSO) for Security contexts: The router supports SSO for security contexts, which allows the router to maintain state information during a switchover, so that connections can be quickly reestablished after a failure.
- Cisco IOS Software redundancy: The router supports the Non-Stop Forwarding (NSF) and Stateful Switchover (SSO) features of Cisco IOS Software, which allow the router to maintain network connectivity during software upgrades or hardware failures.
