More Information

The Cisco EHWIC-4ESG is a 4-port Ethernet interface module for Cisco routers that provides enhanced high-speed WAN connectivity options. It is designed to support Ethernet, Fast Ethernet, and Gigabit Ethernet interfaces, and can be used to connect Cisco routers to LANs and WANs. The module supports a variety of interface types, including copper and fiber, and can be used in a wide range of applications, including enterprise, service provider, and industrial environments. It is compatible with a range of Cisco routers, including the Cisco Integrated Services Router (ISR) and the Cisco Aggregation Services Router (ASR).


The Cisco EHWIC-4ESG is a 4-port Gigabit Ethernet interface module designed for use with Cisco Integrated Services Routers (ISRs). Here are some advantages of using this module:

  • Increased network performance: With four high-speed Gigabit Ethernet ports, the EHWIC-4ESG provides a significant increase in network performance compared to traditional Ethernet interfaces. This allows for faster data transfer and improved network efficiency.
  • Improved scalability: The EHWIC-4ESG allows for easy expansion of network interfaces, making it easy to scale up network resources as needed. This can be particularly useful for businesses that are experiencing growth or increasing demand for network services.
  • Simplified network management: The EHWIC-4ESG can be managed using the same tools and interfaces as other Cisco networking products, making it easy to integrate into existing networks. This allows for a consistent user experience and simplified network management.
  • Enhanced network security: The EHWIC-4ESG includes advanced security features such as access control lists (ACLs), port security, and 802.1x authentication. These features help to protect the network from unauthorized access and ensure that data is kept secure.
  • Flexible deployment options: The EHWIC-4ESG is designed to work with a variety of Cisco ISR models, providing flexibility in deployment and allowing businesses to choose the router that best fits their needs.

Management and Configuration

The Cisco EHWIC-4ESG is a 4-port Gigabit Ethernet interface module that can be installed in Cisco routers and switches with EHWIC slots. This module provides high-speed Ethernet connectivity for network devices and can be used to expand the number of Ethernet ports available on a network device.

Here is an overview of the management and configuration of the Cisco EHWIC-4ESG module:

  • Physical installation: Before configuring the module, it must be physically installed in an EHWIC slot on the router or switch. Once installed, the module should be recognized by the network device and the ports should become active.
  • Configuration: To configure the module, it must first be assigned an IP address. This can be done using the router or switch command-line interface (CLI) or a network management tool such as Cisco Prime Infrastructure. Once an IP address is assigned, the module can be configured using the CLI or a network management tool.
  • VLAN Configuration: The Cisco EHWIC-4ESG module supports virtual LANs (VLANs) and can be configured to support multiple VLANs. VLANs allow for segmentation of network traffic, improving network performance and security. VLANs can be configured using the CLI or a network management tool.
  • Quality of Service (QoS) Configuration: QoS allows for prioritization of network traffic based on different criteria, such as application type or source/destination IP address. The Cisco EHWIC-4ESG module supports QoS and can be configured to prioritize network traffic. QoS can be configured using the CLI or a network management tool.
  • Security Configuration: The Cisco EHWIC-4ESG module supports a range of security features, including access control lists (ACLs), port security, and 802.1x authentication. These features can be configured using the CLI or a network management tool.
  • Monitoring and Management: The Cisco EHWIC-4ESG module can be monitored and managed using a range of tools, including the Cisco IOS CLI, Simple Network Management Protocol (SNMP), and Cisco Prime Infrastructure. These tools allow for monitoring of network performance, configuration changes, and security events.
