Description
Management of Network Bandwidth
Managing network bandwidth on the C2911-CME-SRST/K9 Cisco 2911 Router Voice Bundle with Packet Voice DSP Module can be done by configuring Quality of Service (QoS) features on the router. Some of the common steps to manage network bandwidth would be:
- Configure Quality of Service (QoS) policies: The router supports QoS, which can be used to prioritize different types of network traffic. This can be used to ensure that critical voice and video traffic is given priority over less-critical data traffic. QoS policies can be configured on the router to classify, mark, shape, and police network traffic.
- Classify traffic: The first step in configuring QoS is to classify the traffic. This can be done by using access control lists (ACLs) to match specific traffic based on IP addresses, ports, protocols, or other criteria.
- Mark traffic: Once the traffic is classified, it can be marked with a specific value, such as a Differentiated Services Code Point (DSCP) or an IP Precedence value. This marking is used to indicate the level of priority for the traffic.
- Shape traffic: Shaping can be used to limit the amount of bandwidth that is available to specific types of traffic. This can be used to ensure that certain types of traffic, such as voice or video, are given priority over other types of traffic.
- Police traffic: Policing can be used to limit the amount of bandwidth that is available to specific types of traffic. This can be used to ensure that certain types of traffic, such as voice or video, are given priority over other types of traffic.
- Monitor and verify the bandwidth usage: Regularly monitoring and verifying the bandwidth usage can help you to identify any potential bottlenecks or issues. You can use the ‘show policy-map interface’ command to check the status of the QoS policies, ‘show interface’ command to check the bandwidth usage of the interfaces, and ‘show queueing’ command to check the queue status.
Routing Protocols and Configuration
The C2911-CME-SRST/K9 Cisco 2911 Router Voice Bundle with Packet Voice DSP Module can support various routing protocols, depending on the software version. The most common routing protocols that can be configured on this router are:
- Interior Gateway Routing Protocol (IGRP): IGRP is a Cisco proprietary routing protocol that is used to exchange routing information within a single autonomous system (AS). This protocol can support a maximum of 100 active routes and has a maximum hop count of 100.
- Enhanced Interior Gateway Routing Protocol (EIGRP): EIGRP is a Cisco proprietary routing protocol that is based on IGRP but has been enhanced to support a larger number of active routes and a larger hop count. EIGRP also supports advanced features such as unequal cost load balancing, and support for IPv6.
- Open Shortest Path First (OSPF): OSPF is an open standard routing protocol that is used to exchange routing information within a single autonomous system (AS). This protocol supports a hierarchical network design, and it’s a link state routing protocol.
- Border Gateway Protocol (BGP): BGP is a routing protocol that is used to exchange routing information between different autonomous systems (AS). BGP is typically used to connect to the Internet or other service providers.
- Routing Information Protocol (RIP): RIP is a distance-vector routing protocol that is used to exchange routing information within a single autonomous system (AS). This protocol has a maximum hop count of 15.
To configure routing protocols, you need to use the appropriate commands and configurations in the router’s command-line interface (CLI).
Security Features
The C2911-CME-SRST/K9 Cisco 2911 Router Voice Bundle with Packet Voice DSP Module includes several security features that can be used to protect the network from various types of attacks. Some of the most common security features that can be configured on this router are:
- Access Control Lists (ACLs): ACLs can be used to control access to the network based on the source and destination IP addresses, ports, and protocols. ACLs can be used to filter out unwanted traffic, such as traffic from known malicious sources.
- Network Address Translation (NAT): NAT allows the router to translate the internal IP addresses of the devices on the network to a public IP address that is used to connect to the Internet. This can help to hide the internal IP addresses of the devices on the network and make it more difficult for external attackers to target them.
- Virtual Private Network (VPN): VPN allows the router to create secure, encrypted connections between remote devices and the network. This can be used to protect sensitive data as it travels over the Internet and can be used to connect remote offices or mobile users to the network.
- Firewall: Firewall can be used to block unauthorized access to the network. The firewall can be configured to block specific types of traffic, such as traffic from known malicious sources. The firewall can also be configured to block specific types of attacks, such as denial-of-service (DoS) attacks.
- Authentication, Authorization and Accounting (AAA): AAA enables the router to authenticate users before allowing them to access the network and to track their activity once they are connected. This can be used to ensure that only authorized users are able to access the network and to monitor network activity for suspicious behavior.
- Intrusion Detection and Prevention System (IDPS): IDPS can be used to detect and block attempted intrusions into the network. This can be used to detect and block a wide range of attacks, including those that exploit known vulnerabilities in the software or hardware used in the network.
