Performance of Interface Card

The Cisco EHWIC-4ESG-P (Enhanced High-Speed WAN Interface Card) is a high-performance WAN interface card that can be used to add four Gigabit Ethernet (GE) ports to a Cisco router. It is designed to provide high-speed, secure, and reliable connectivity for branch offices, teleworker sites, and other remote locations.

This card is a high-performance card that supports 4 Gigabit Ethernet (GE) ports, each of which can be configured as WAN or LAN ports. It supports multiple interface types, including Ethernet, Fast Ethernet and Gigabit Ethernet.

This item card is compliant with industry standards, including IEEE 802.3 (Ethernet), IEEE 802.3u (Fast Ethernet) and IEEE 802.3z (Gigabit Ethernet).

It also supports advanced features such as Quality of Service (QoS), Virtual LANs (VLANs), Link Aggregation Control Protocol (LACP), and Link Layer Discovery Protocol (LLDP).

It also supports IPv4 and IPv6 routing and can be configured for various routing protocols such as static, OSPF, EIGRP, BGP, and IS-IS.

This card can be used with a variety of Cisco routers, including the Cisco 1800, 2800, 3800, and 3900 series routers, and the Cisco Integrated Services Router (ISR) G2 and G3 platforms.

This item card is designed to be easy to install and maintain, with a hot-swappable design that allows it to be added or removed from the router without disrupting network operations.

Reliability for Switching Interface Card

The EHWIC-4ESG-P (Ethernet High-Speed WAN Interface Card) is a Cisco WAN interface card designed to provide high-speed connectivity for Cisco routers. This card provides four Gigabit Ethernet ports, which can be configured for various WAN protocols, including Ethernet, PPPoE, and VLAN.

In terms of reliability, this product is designed to provide a high level of availability and uptime for critical network applications. It supports several features that enhance reliability, such as:

  • Link Aggregation Control Protocol (LACP) which allows multiple physical links to be bundled together to form a single logical link, providing increased bandwidth and redundancy.
  • Hot-swappable design, which allows the card to be replaced without affecting the operation of the router.
  • Quality of Service (QoS) which allows for traffic prioritization, and ensures that critical applications receive the necessary bandwidth.
  • 802.1X security, which allows for secure access to the network and prevents unauthorized access.
  • Cisco IOS Software, which is known for its stability and security.

It is also worth noting that, as with any network equipment, the reliability of this product is highly dependent on the proper installation, configuration, and maintenance of the card and the surrounding network.

Compliant Standards

This model Cisco WAN Interface Card (WIC) is a network interface card (NIC) that provides four Gigabit Ethernet ports for use in Cisco routers. This card is compliant with a variety of industry standards, including:

  • IEEE 802.3ab 1000BASE-T: Gigabit Ethernet standard for operation over copper twisted-pair cables with a maximum distance of 100 meters.
  • IEEE 802.3z 1000BASE-X: Gigabit Ethernet standard for operation over fiber optic cables.
  • IEEE 802.3x Flow Control: Standard for controlling data flow in Ethernet networks to prevent network congestion.
  • PCI Express 2.0: Standard for connecting peripheral devices to a computer's motherboard.
  • RoHS (Restriction of Hazardous Substances)
