What IS EHWIC?
What IS EHWIC?
Definition. EHWIC. Enhanced High-Speed WAN (Wide Area Network) Interface Card (Cisco)
What is a Cisco card?
A WAN interface card, or “WIC” is a type of specialized network interface controller card (NIC) made by Cisco that allows a network device such as a router to connect and transmit data over a wide area network.
What is the difference between a directly connected network and a remote network?
Directly connected routes—These routes come from the active router interfaces. Routers add a directly connected route when an interface is configured with an IP address and is activated. Remote routes—These are remote networks connected to other routers.
When you ping from a router to another router and receive back this mean?
PING – You can use the PING command to send test packets to a particular device. If you get a response back, you know there is a physical connection between the two devices. If no response is returned, this could indicate a problem with the physical connection.
What happens to a routing table if the router loses power?
To save those changes in case the router is restarted or loses power, the running-config file must be copied to NVRAM, where it is stored as the startup-config file. NVRAM retains its contents even when the router is powered off.
Do I connect my router to WAN or LAN?
Do I plug Ethernet into WAN or LAN? You need to connect your home network devices to the LAN ports on your router. WAN is only used to connect the router to the modem.
How do NICs work?
A NIC provides a computer with a dedicated, full-time connection to a network. It implements the physical layer circuitry necessary for communicating with a data link layer standard, such as Ethernet or Wi-Fi. Each card represents a device and can prepare, transmit and control the flow of data on the network.
How do I install a network interface card?
Beta Program
- Assemble your materials.
- Shut down Windows, turn off the computer and unplug it.
- Remove the cover from your computer.
- Find an unused expansion slot inside the computer.
- Remove the metal slot protector from the back of the computer’s chassis.
- Insert the network interface card into the slot.
What is the purpose of ICMP messages?
Explanation:The purpose of ICMP messages is to provide feedback about issues that are related to the processing of IP packets.
What is ehwic-1ge-sfp-cu?
Figure 1. Cisco Gigabit Ethernet EHWIC-1GE-SFP-CU Figure 2 shows an ISR G2 with two EHWICs: one connected to the branch-office LAN, and one connected to an EWAN service. On the LAN side, the card can run multiple VLANs to segregate LAN networks.
Does EHWIC have SFP ports?
For flexibility, the EHWIC includes one SFP slot, which supports a Cisco SFP (see Table 1 later in this document) and a copper RJ-45 port, where either the SFP port (operating at 100/1000 Mbps) or the RJ-45 (operating at 10/100/1000 Mbps) port can be active at one time.
Does the ehwic-1ge-sfp-CU support VLAN Trunking?
Since this is a true routed port card, the user can configure an IP address directly on the EHWIC-1GE-SFP-CU interface and does not have to configure the port for VLAN trunking as is done in switched virtual interface (SVI) configurations. Figure 1. Cisco Gigabit Ethernet EHWIC-1GE-SFP-CU
What is the maximum throughput for The ehwic?
The maximum throughput cannot exceed 800 Mbps bidirectionally. For flexibility, the EHWIC includes one SFP slot, which supports a Cisco SFP (see Table 1 later in this document) and a copper RJ-45 port, where either the SFP port (operating at 100/1000 Mbps) or the RJ-45 (operating at 10/100/1000 Mbps) port can be active at one time.
