Introduction to the Ethernet Switch
The HWIC-4ESW= is a Hot-swappable WAN Interface Card (HWIC) for the Cisco 2800 Series routers. It provides 4 Fast Ethernet ports for connecting to LAN devices or WAN services. The HWIC-4ESW= allows customers to add high-speed Ethernet connectivity to their Cisco 2800 Series routers, increasing network bandwidth and providing additional connectivity options. The HWIC-4ESW= supports various networking protocols and features, such as Quality of Service (QoS), VLANs, and Link Aggregation Control Protocol (LACP). This makes it suitable for use in a wide range of networking environments, from small branch offices to large data centers. Additionally, the HWIC-4ESW= supports both managed and unmanaged modes of operation, allowing customers to choose the level of network control that best fits their needs.
Routing and Switching Protocols
The HWIC-4ESW= Cisco 2800 Series 4 Ports Ethernet Switch supports the following routing and switching protocols:
Routing Protocols:
- Routing Information Protocol (RIP)
- Open Shortest Path First (OSPF)
- Enhanced Interior Gateway Routing Protocol (EIGRP)
- Border Gateway Protocol (BGP)
Switching Protocols:
- Virtual LAN (VLAN)
- Link Aggregation Control Protocol (LACP)
- Spanning Tree Protocol (STP)
- Rapid Spanning Tree Protocol (RSTP)
- Multiple Spanning Tree Protocol (MSTP)
These routing and switching protocols help enable advanced network capabilities, such as dynamic routing, load balancing, network resiliency, and security. They also allow the HWIC-4ESW= to be easily integrated into existing network environments, providing seamless communication between devices.
Power Options and Redundancy
The HWIC-4ESW= Cisco 2800 Series 4 Ports Ethernet Switch provides the following power options and redundancy features to ensure reliable network connectivity:
- Power: The HWIC-4ESW= can be powered either by an external power supply or by the internal power supply of the router in which it is installed.
- Redundancy: To ensure high-availability Ethernet connectivity, the HWIC-4ESW= supports Link Aggregation Control Protocol (LACP), which allows multiple physical links to be combined into a single logical link. This helps ensure that if one of the physical links fails, traffic can still be transmitted over the remaining links.
In addition, the Cisco 2800 Series routers support redundant power supplies, which help ensure that the network can continue operating even if one of the power supplies fails. These power options and redundancy features help ensure that the HWIC-4ESW= can provide reliable and high-availability Ethernet connectivity for critical network applications.
