In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.

What is the command to determine if interface Ethernet 0 is active?

Run "ipconfig".. If your Ethernet will be active it will show you the current IP address of NIC..


How would a technician permanently change the IP address of an Ethernet card on a Red Hat Linux PC?

Command to change the IP address on Linux is ifconfig.Run ifconfig to find the interface name for the connected Ethernet card. If there is only on ethernet card present on your system then the interface name would be eth0. If there are more than one Ethernet cards present on your machine then they interface names will be ethn.Once you have figurred out the interface name then ifconfig command can be used to modify the IP address$ ifconfig eth0 upeg$ ifconfig eth0 192.168.1.100 upWould assign new IP address to eth0


Which interface requires an ip address to transport ios or configuration files from the router to a tftp server on the lan?

Ethernet


What happens when a node on an Ethernet network is creating a frame and it does not have the destination MAC address?

The node sends out an ARP request with the destination IP address.


What will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?

On a hub network:The host (PC-A) computer sends the frame out its Network Interface Card (NIC) to Fast-Ethernet 0/1 (F0/1) on the HUB. The HUB then sends that frame out every interface (except incoming interface). If the destination MAC address is aaa.bbb.ccc, and PC-B has MAC address aaa.aaa.bbb, then PC-B's NIC will ignore the frame and nothing else will happen.


What would happen when you manually added an entry you entered the correct i p address but the wrong Ethernet address for that remote interface?

Once the router/adaptor received the destination IP address (even if we entered in the incorrect MAC address) the router/adapter would remove the IP address from the Ethernet frame and using ARP, would get the correct MAC address of the destination


Find Mac address for apple computer?

Two simple ways: 1. Using System Preferences: * Open System Preferences * Click "Network" * Select the interface from the list (e.g. "Ethernet" or "AirPort") * Click "Advanced" * Look through the tabs; one will contain the mac address. (If you're looking for the Ethernet interface, it will be under the "Ethernet" tab; if you're looking for Airport, the address is under the "AirPort" tab) 2. Using Terminal: * Open Terminal * Type "ifconfig" (without the quotes) and hit enter * Look through the list until you see the correct interface. The mac address wil be in that section (it will say something like "ether 00:11:22:aa:bb:cc") * Alternatively, you can enter "ifconfig <interface>" to only view that interface. Ethernet is usually en0 and AirPort usually en1 (but not always). For example, type "ifconfig en1" to view the AirPort's configuration.


Ethernet address in hex?

Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal digits (0-9, plus A-F, capitalized). These 12 hex digits consist of the first/left 6 digits (which should match the vendor of the Ethernet interface) and the last/right 6 digits which specify the interface serial number for that interface vendor. These high-order 3 octets (6 hex digits) are also known as the Organizationally Unique Identifier or OUI. A list of ethernet vendors are at : <URL:http://www.cavebear.com/CaveBear/Ethernet/vendor.html> <URL:ftp://ftp.cavebear.com/pub/Ethernet-codes> <URL:gopher://ftp.cavebear.com/00/pub/Ethernet-codes>


What is physical address?

The low level addressing scheme used on Ethernet. The 48-bit destination Ethernet address in a packet is compared with the receiving node's Ethernet address.

What is a private MAC address?

A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.


How do you get Mac address?

You don't "Get" one, because you already have one. A MAC Address uniquely identifies your computer's network interface card on the network. If you're asking how do you know what your MAC address is:Windows:Start>Run>type "cmd"in the black window that appears type "ipconfig /all"the MAC address will be listed as "Physical Address" and usually starts with 00-In Mac OS X 10.5 and later, in the left column of the Network preference window that opens, click the name of your connection (e.g., AirPort, Ethernet, Built-in Ethernet). Click the Advanced... button, and in the sheet that drops down, click either the Ethernet or AirPort tab. The string of letters and numbers next to "Ethernet ID:" or "AirPort ID:" is your MAC address.In Mac OS X 10.3 or 10.4, in the Network preference window that opens, make sure the pull-down menu next to "Show:" lists your connection (e.g., AirPort, Built-in Ethernet). Under the Ethernet or AirPort tab, the string of letters and numbers next to "Ethernet ID:" or "AirPort ID" is your MAC address.Alternatively, you could use "ifconfig -a"Linux:Open a shell, use "ifconfig -a". This will display your current network settings for each interface available on your computer.An example of what a MAC address would look like:00-FF-20-58-C9-60*NOTE* all devices that access the internet have a MAC address (iPhone, PS3, PSP, Switches, Firewalls, Routers, cable modems, cell phones, etc)Wikipedia:In computer networking, a Media Access Control address(MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address.http://en.wikipedia.org/wiki/Mac_address
