The Cisco EtherSwitch HWIC (part number HWIC-4ESW=) is a hardware component designed to expand networking capabilities in compatible Cisco integrated service routers (ISR). This switch is a managed device, offering enhanced control over network operations and providing the necessary infrastructure for seamless data management. The HWIC-4ESW= features four Fast Ethernet ports that support data rates of 10/100 Mbps, enabling reliable and flexible connectivity for various network applications.
One of the key attributes of the Cisco EtherSwitch HWIC is its plug-in design, which allows for easy integration with routers without the need for additional standalone switches. Each port in the switch supports auto-sensing functionality for speed and duplex mode, ensuring that the device communicates efficiently with other networking components. Another invaluable feature is its full power over Ethernet (PoE) support, allowing compatible devices connected to the switch to receive electrical power alongside data through a single Ethernet cable, maximising efficiency for installed devices like IP phones and wireless access points.
Management of the Cisco EtherSwitch HWIC can be done through Cisco IOS, and the switch provides an array of VLAN capabilities, including support for inter-VLAN routing. This makes it easier to segregate different types of traffic for enhanced security and performance. Additionally, the hardware includes support for QoS features, such as traffic prioritisation based on various parameters, ensuring that critical applications receive the bandwidth they need.
In summary, the Cisco EtherSwitch HWIC (HWIC-4ESW=) is a flexible and reliable solution for expanding network connectivity in business environments, providing important features such as managed switching, VLAN support, PoE compatibility, and intelligent data routing within Cisco routers.
