Application Optimization and Performance

The Cisco 1921 Multi Service Router (C1921-3G-U-SEC/K9) is a modular router that is designed to provide a range of services, such as routing, security, and voice, for small to medium-sized businesses and enterprise branch offices. The router has 2 ports and a management port and 2 slots, which can be configured with different module to optimize the performance of the router for specific applications. Some of the features that can be used to optimize the router's performance include:

  • Quality of Service (QoS): This feature allows for the prioritization of different types of network traffic, such as voice and video, to ensure that these types of traffic are given priority over less time-sensitive traffic like file transfers or web browsing. This can be done through the use of traffic classes, which are defined by the administrator and assigned to different types of traffic, and queuing mechanisms, which determine how traffic is handled as it enters and exits the router.
  • Access Control Lists (ACLs): These are used to control access to specific network resources, such as servers or applications. ACLs can be used to block unwanted traffic, such as malware or DDoS attacks, and to ensure that only authorized users can access specific resources.
  • Firewall: This feature can be used to block unwanted traffic and protect the network from external threats. The router's firewall can be configured to block specific types of traffic, such as incoming ICMP packets, and to allow only specific types of traffic, such as HTTP traffic to a web server.
  • Virtual Private Network (VPN): This feature allows for secure remote access to the network by encrypting traffic as it traverses the public internet. This can be used to allow employees to access the network remotely or to connect branch office networks together securely.
  • Load Balancing: This feature allows for distributing the load of incoming traffic across multiple servers or devices, This can be done through the use of features such as server load balancing, which directs incoming traffic to the least busy server, and link load balancing, which distributes traffic across multiple links to improve link utilization.
  • 3G/4G Backup: The router is equipped with a slot for a 3G/4G module, which can be used as a backup for the primary WAN connection, providing an extra layer of reliability for the network.

It's important to note that the specific features and capabilities of the management and monitoring tools will depend on the specific software version and memory capacity installed on the router as well as the modules that are installed on the router. It's recommended to consult with Cisco documentation, or a Cisco certified professional, to ensure the best configuration and performance for the specific needs of the network.

Management and Monitoring Tools

The Cisco 1921 Multi Service Router (C1921-3G-U-SEC/K9) can be managed and monitored through a variety of built-in tools and interfaces. These may include:

  • Command-Line Interface (CLI): The router's CLI can be accessed through a terminal emulator such as PuTTY, and provides access to a wide range of commands for configuring and monitoring the router. This can be done by connecting to the router using Telnet or SSH, and logging in with an appropriate username and password.
  • Web-based Interface: The router may also include a web-based interface, which allows for the configuration and monitoring of the router through a web browser. This interface can be accessed by typing the router's IP address into the browser's address bar and logging in with an appropriate username and password.
  • Simple Network Management Protocol (SNMP): The router may also include SNMP support, which allows for remote monitoring and management of the router. SNMP uses a management information base (MIB) to define the different parameters that can be monitored, and an SNMP agent on the router to collect and respond to SNMP requests.
  • Network Management Systems (NMS): The router can also be managed and monitored using a Network Management System (NMS) such as Cisco Prime or SolarWinds. These systems provide a centralized management and monitoring platform, allowing network administrators to manage multiple devices from a single interface.
  • Logging and syslog: The router can also be configured to log events and send them to a syslog server. This can help to track and troubleshoot issues with the router and the network, and can be used for auditing and compliance purposes.
  • Event Management and Notifications: Some of the above tools such as Cisco Prime, SolarWinds or other third-party software allows to set up event management and notifications. This means that you can configure the system to send notifications (e.g., email, SMS) when certain events occur (e.g., interface status change, high CPU usage).

It's important to note that the specific features and capabilities of the management and monitoring tools will depend on the specific software version and memory capacity installed on the router as well as the modules that are installed on the router. It's recommended to consult with Cisco documentation, or a Cisco certified professional, to ensure the best configuration and performance for the specific needs of the network.

Network and Security Features

The Cisco 1921 Multi Service Router (C1921-3G-U-SEC/K9) is designed to provide a range of network and security features for small to medium-sized businesses and enterprise branch offices. Some of the network and security features that may be included are:

  • Routing: The router can be configured to route traffic between different networks using protocols such as OSPF, EIGRP, and BGP.
  • Network Address Translation (NAT): This feature allows for the translation of private IP addresses to public IP addresses, allowing devices on a private network to access the internet.
  • VPN: This feature allows for secure remote access to the network by encrypting traffic as it traverses the public internet. This can be used to allow employees to access the network remotely or to connect branch office networks together securely.
  • Firewall: This feature can be used to block unwanted traffic and protect the network from external threats. The router's firewall can be configured to block specific types of traffic, such as incoming ICMP packets, and to allow only specific types of traffic, such as HTTP traffic to a web server.
  • Access Control Lists (ACLs): These are used to control access to specific network resources, such as servers or applications. ACLs can be used to block unwanted traffic, such as malware or DDoS attacks, and to ensure that only authorized users can access specific resources.
  • Intrusion Prevention System (IPS): This feature provides protection against a variety of network-based attacks by detecting and blocking malicious traffic.
  • Secure Shell (SSH): This feature provides a secure method for remotely accessing the router's command-line interface (CLI) using an encrypted connection.
  • Secure Sockets Layer (SSL): This feature provides a secure method for remotely accessing the router's web-based interface using an encrypted connection.
  • 3G/4G Backup: The router is equipped with a slot for a 3G/4G module, which can be used as a backup for the primary WAN connection, providing an extra layer of reliability for the network.

It's important to note that the specific features and capabilities of the security features will depend on the specific software version and memory capacity installed on the router as well as the modules that are installed on the router. It's recommended to consult with Cisco documentation, or a Cisco certified professional, to ensure the best configuration and performance for the specific needs of the network.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.

A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.

Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.

Important Features

Multi-core Processor

The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.

Multi-band options

Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5GHz.

Built-in Security Features

These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cybercriminals will be unable to infiltrate home networks.

Types of Routers

There are several types of routers that users can benefit from. Some of them include:

  • Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
  • Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
  • Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
  • Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
  • Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
  • Logical Routers. They function similarly to hardware to create several network routes.
