Management of Network Bandwidth
The CISCO1941/K9 Cisco 1941 2 Ports Services Router provides several features to manage the bandwidth of the network. Some of these features are:
- Traffic shaping: This feature allows you to control the rate at which traffic is sent, ensuring that the network does not become congested. You can configure traffic shaping to limit the amount of bandwidth used by certain types of traffic, such as video or VoIP, to ensure that they do not consume too much bandwidth.
- Class-based queuing: This feature allows you to divide traffic into different classes, and assign different priorities to each class. You can use class-based queuing to ensure that certain types of traffic, such as VoIP or video, are given priority over other types of traffic.
- Priority queuing: This feature allows you to assign a priority level to certain types of traffic, ensuring that they are processed before other traffic. You can use priority queuing to ensure that time-sensitive traffic, such as VoIP or video, is given priority over other types of traffic.
- Low Latency Queuing (LLQ): This feature allows you to assign a priority level to certain types of traffic, ensuring that they are processed before other traffic, with minimal delay. This feature is particularly useful for time-sensitive applications, such as VoIP or video.
- Weighted Random Early Detection (WRED): This feature allows you to drop packets before a queue becomes full, reducing congestion. This feature can be used to ensure that the network does not become congested, even during periods of high traffic.
- Weighted Fair Queuing (WFQ): This feature allows you to divide traffic into different classes, and assign different priorities to each class, based on the IP address, protocol, and other fields.
- Quality of Service (QoS) groups: You can use QoS groups to classify and prioritize traffic at different levels.
- Control-plane policing (CoPP): This feature allows you to limit the amount of bandwidth consumed by control plane traffic to ensure that it does not consume too much bandwidth and affect the network performance.
Remote Management Protocols
The CISCO1941/K9 Cisco 1941 2 Ports Services Router supports several remote management protocols that can be used to configure and manage the router remotely. Some of these protocols are:
- Telnet: Telnet is a remote management protocol that allows you to connect to the router using a Telnet client and a username and password. Telnet is an unencrypted protocol, so it is not recommended to use Telnet for remote management.
- SSH: SSH (Secure Shell) is a remote management protocol that allows you to connect to the router using an SSH client and a username and password. SSH is an encrypted protocol, so it is more secure than Telnet.
- SNMP: SNMP (Simple Network Management Protocol) is a remote management protocol that allows you to monitor and manage the router using an SNMP management system. SNMP uses a series of management information bases (MIBs) to represent the router’s configuration and status.
- HTTP and HTTPS: The CISCO1941/K9 Cisco 1941 2 Ports Services Router supports HTTP and HTTPS protocols, which can be used to access the web-based graphical user interface (GUI) of the router. The HTTPS protocol provides an encrypted connection and is more secure than the HTTP protocol.
- Cisco Discovery Protocol (CDP): CDP is a Cisco proprietary protocol that allows network devices to discover other Cisco devices that are connected to the same network. CDP can be used to discover the CISCO1941/K9 Cisco 1941 2 Ports Services Router and other Cisco devices on the network and to obtain information about the devices.
- Remote Management via GUI (ASDM): The router also supports Cisco Adaptive Security Device Manager (ASDM), which is a web-based GUI for managing and configuring Cisco security devices.
It is recommended to use the most secure remote management protocols, such as SSH and HTTPS, for remote management of the CISCO1941/K9 Cisco 1941 2 Ports Services Router. It is also important to properly secure the remote management protocols by implementing proper authentication and access control mechanisms.
Advanced Security Features
The CISCO1941/K9 Cisco 1941 2 Ports Services Router supports several advanced security features that can be used to secure the network. Some of these features are:
- Firewall: The router includes a built-in firewall that can be used to control and restrict incoming and outgoing traffic based on predefined rules. The firewall can be configured to block certain types of traffic, such as malicious traffic or traffic from specific IP addresses.
- Virtual Private Network (VPN): The router supports several VPN protocols, such as IPSec, L2TP, and PPTP, which can be used to create secure, encrypted tunnels between the router and remote devices. This feature allows remote users to securely access the network as if they were connected directly to it.
- Network Address Translation (NAT): NAT is a technique that allows the router to translate private IP addresses to public IP addresses. NAT allows the router to hide the internal network from the external network, increasing security by making it more difficult for external devices to directly access internal devices.
- Intrusion Prevention System (IPS): The router supports the Intrusion Prevention System (IPS) feature which helps to detect and prevent malicious traffic from entering the network.
- Access Control Lists (ACLs): The router supports ACLs, which can be used to control access to the network based on predefined rules. ACLs can be used to restrict access to certain IP addresses, ports, or protocols, or to block traffic from specific IP addresses.
- Dynamic Host Configuration Protocol (DHCP) snooping: DHCP snooping is a security feature that helps to prevent malicious DHCP servers from assigning IP addresses to devices on the network.
- Port Security: Port security is a feature that allows you to restrict the number of MAC addresses that can be learned on a port, and also to specify which MAC addresses are allowed to access the port.
- Cisco Identity Services Engine (ISE): Cisco Identity Services Engine (ISE) is a network access control (NAC) solution that allows you to control network access based on the identity of the device or user.
- Advanced Malware Protection (AMP): The router includes an Advanced Malware Protection (AMP) feature which helps to detect and prevent malware from entering the network.
