Introduction to the Interface Card
The HWIC-D-9ESW is a WAN Interface Card (WIC) for Cisco 2800 series routers. It provides nine 10/100Mbps Ethernet ports for connecting to external networks or devices. The card is installed in the expansion slot of the router and is used to interface the router with Ethernet networks.
This is designed for use in small to medium-sized enterprise environments, where it can be used to connect the router to a variety of different types of Ethernet networks. The card can be used to connect the router to a wired or wireless LAN, a WAN, or a metro Ethernet network.
One of the key features of the model is its ability to support both VLAN tagging and VLAN trunking, which allows for efficient use of network resources and improved security. VLAN tagging allows multiple logical networks to share the same physical network infrastructure, while VLAN trunking allows the router to pass VLAN tags between multiple VLANs.
Another feature of the model is the support for Quality of Service (QoS) mechanisms, which are used to prioritize and shape network traffic to ensure that critical applications and services receive the necessary bandwidth and low latency.
This is designed for use with the Cisco 2800 series routers, which are versatile, modular platforms that can be used for a wide range of enterprise applications, including routing, security, voice, and wireless. They are also capable of supporting a wide range of interface cards and modules, making them highly scalable and configurable.
Features and Benefits
The performance of the HWIC-D-9ESW Cisco 2800 Series 9-Ports 10/100Mbps Ethernet Switch WAN Interface Card will depend on several factors, including the specific Cisco 2800 series router it is installed in, the network traffic and usage patterns, and the quality of the external networks or devices connected to it.
In general, the model should be able to handle a large amount of network traffic, with a switching capacity of up to 11.9 Gbps. Each of the nine 10/100Mbps Ethernet ports can handle full-duplex traffic, which allows for both transmitting and receiving data simultaneously. This should allow for high-speed data transfer between connected devices, and minimizes delays in data transfer.
The model also support Quality of Service (QoS) mechanisms, which can help ensure that critical applications and services receive the necessary bandwidth and low latency. QoS allows to prioritize certain type of traffic and decrease jitter, delay and packet loss that can cause packet re-transmission which in turn can slow down network traffic.
Additionally, the support for VLAN tagging and VLAN trunking allows for efficient use of network resources and improved security. VLAN tagging allows multiple logical networks to share the same physical network infrastructure, while VLAN trunking allows the router to pass VLAN tags between multiple VLANs.
It is important to note that the performance of the model can also be affected by factors such as the number and type of devices connected to it, the network topology, and the routing protocols being used. It's always recommended to do a proper network analysis, a survey and design before deploying this solution for a specific use case.
Interface Provided for Digital Workplace
The model Cisco 2800 Series 9-Ports 10/100Mbps Ethernet Switch WAN Interface Card can provide interfaces for a digital workplace in several ways, depending on the specific network configuration and requirements of the organization.
One common use case for the model in a digital workplace is to provide network connectivity for employee devices such as computers, laptops, and smartphones. The nine 10/100Mbps Ethernet ports on the card can be used to connect these devices to the network, allowing employees to access the internet, company resources, and applications.
The card's support for VLAN tagging and VLAN trunking can also be used to segment the network, creating separate virtual networks for different types of devices or groups of users. This can help improve security by isolating different parts of the network and controlling access to resources.
Another use case for the model in a digital workplace is to provide connectivity for IP-based telephony and videoconferencing systems. The card's Ethernet ports can be used to connect these systems to the network, allowing employees to make and receive calls and participate in video conferences.
Additionally, the card also support Quality of Service (QoS) mechanisms, which can help ensure that critical real-time applications and services such as voice, video and virtual meeting receive the necessary bandwidth and low latency.
It's important to note that the model must be used in conjunction with a Cisco 2800 series router and other network devices, such as switches and firewalls, to provide a complete network solution for a digital workplace. A proper network design, security measures, and management must be in place to have the best performance, reliability and usability of the network.
