GRWIC-D-ES-2S-8PC Cisco EtherSwitch Service Module Refurbished

The Cisco GRWIC-D-ES-2S-8PC is a specialized service module designed to enhance networking capabilities within Cisco Integrated Services Routers (ISRs). This module significantly expands the router's functionality, enabling advanced networking features and accommodating various connectivity needs.

Service modules are add-ons or expansion cards that extend the capabilities of networking devices, like routers. They offer additional ports, interfaces, and functions beyond the built-in features of the router itself.

This service module is equipped with 8 LAN (Local Area Network) ports, each supporting data transfer at speeds of up to 10/100Base-TX. These ports facilitate connections to various devices within a network, such as computers, printers, or other networking equipment.

In addition to the LAN ports, the module includes one Gigabit Ethernet port capable of supporting data transfer rates of 10/100/1000Base-T. This high-speed port is suitable for faster connections or uplinking to other networks.

The Cisco GRWIC-D-ES-2S-8PC features two Small Form-Factor Pluggable (SFP) slots, which are versatile interfaces that allow flexibility in connecting various types of networking media. These slots can support SFP (mini-GBIC) modules for specific connectivity needs, such as optical fiber or copper connections.

With two expansion slots, this service module offers scalability for future enhancements or additional functionalities. Users can add compatible expansion cards to further expand the router's capabilities according to their evolving networking requirements.

The GRWIC-D-ES-2S-8PC service module is an ideal solution for businesses or organizations aiming to expand their existing network infrastructure. Its multiple LAN ports and Gigabit Ethernet support enable seamless integration of new devices and faster data transfer.

The inclusion of SFP slots provides adaptability to various networking environments. These slots allow the use of different SFP modules, offering flexibility in connecting over different media types, distances, and speeds, depending on specific networking needs.

The presence of expansion slots ensures scalability, allowing users to adapt to changing networking requirements. This feature enables easy integration of new technologies and services without the need for complete overhauls of the networking setup.

The GRWIC-D-ES-2S-8PC service module is designed to seamlessly integrate into Cisco ISR (Integrated Services Router) platforms that support its form factor and technical specifications. Compatibility should be verified with the specific router model to ensure seamless integration and functionality.

The GRWIC-D-ES-2S-8PC Cisco EtherSwitch Service Module is designed to provide advanced management capabilities to Cisco routers. The following features contribute to its advanced management capabilities:

• CLI-based Management: The module supports a Command Line Interface (CLI) for advanced configuration and management, enabling network administrators to perform complex network operations and custom configurations.
• SNMP: The module supports the Simple Network Management Protocol (SNMP) for remote monitoring and management of the network, allowing administrators to track network performance and troubleshoot issues.
• Cisco IOS Software: The module runs on the industry-leading Cisco IOS software, providing a rich set of network management and security features, as well as support for advanced routing protocols.
• Quality of Service (QoS): The module supports advanced QoS features, such as traffic shaping and prioritization, to ensure that critical network traffic receives the necessary resources.
• Link Aggregation: The module supports link aggregation protocols, such as LACP, to bundle multiple physical links into a single logical link, increasing bandwidth and improving network resiliency.
• Virtual LAN (VLAN) Support: The module supports the use of VLANs to segment the network into multiple virtual networks, improving network security and reducing network congestion.
• Port Security: The module supports port security, which allows administrators to restrict access to specific switch ports based on the MAC address of the attached device.

GRWIC-D-ES-2S-8PC Cisco EtherSwitch Service Module is a network switch module that provides robust security and dynamic quality of service (QoS) features.

In terms of security, the module includes features such as access control lists (ACLs) and Virtual Private Network (VPN) support to protect against unauthorized access and network threats.

In terms of QoS, the module includes features such as traffic shaping and prioritization to ensure that critical network traffic is given priority over less important traffic. This helps to prevent network congestion and ensure that important applications and services are not affected by delays or dropped packets.

It is designed for use with Cisco Integrated Services Routers (ISRs) and provides 8 Gigabit Ethernet ports, 2 Small Form-Factor Pluggable (SFP) ports, and a variety of advanced features to help improve the performance, security, and reliability of your network.

The GRWIC-D-ES-2S-8PC Cisco EtherSwitch Service Module (ESM) is a highly reliable network module that provides Layer 2 and Layer 3 switching capabilities to Cisco routers. The ESM is designed to be used in conjunction with Cisco Integrated Services Routers (ISRs) and can be easily installed and configured to provide a variety of network services, including VLANs, Quality of Service (QoS), and security features.

The ESM is built on the Cisco EtherSwitch technology, which is known for its high reliability and performance. The ESM is also equipped with a redundant power supply, which ensures that the module continues to operate even if one of the power supplies fails. This redundancy feature further improves the reliability of the ESM.

The ESM also includes several advanced features that help to ensure its reliability. For example, it supports Link Aggregation Control Protocol (LACP) and IEEE 802.3ad Link Aggregation, which allow multiple physical links to be bundled together to form a single logical link. This increases the bandwidth and improves the reliability of the network connection.

In addition, the ESM also supports various security features, such as Access Control Lists (ACLs), to help protect the network against unauthorized access and various network attacks. This helps to further improve the reliability of the ESM.
