How are Ethernet address represented?
Sequences of bytes, including Ethernet addresses, are represented by a sequence of hexadecimal digits, in upper-case or lower-case, separated by colons, periods, or dashes. For example, the broadcast Ethernet address ff:ff:ff:ff:ff:ff can be also be represented as ff. ff.
What is interface Ethernet?
Ethernet networking interface refers to a circuit board or card installed in a personal computer or workstation, as a network client. A networking interface allows a computer or mobile device to connect to a local area network (LAN) using Ethernet as the transmission mechanism.
How many Ethernet addresses are there?
Every device that connects to an IEEE 802 network (such as Ethernet and Wi-Fi) has an EUI-48 address. Common networked consumer devices such as PCs, smartphones and tablet computers use EUI-48 addresses. EUI-64 identifiers are used in: IEEE 1394 (FireWire)
How many Ethernet interfaces do you need for an EtherChannel?
You can form an EtherChannel with up to eight compatibly configured Ethernet interfaces on any module and across modules. All interfaces in each EtherChannel must be the same speed, and you must configure all the interfaces as either Layer 2 or Layer 3 interfaces.
How are Ethernet interfaces used in Ex series switches?
All EX Series switches allow you to group Ethernet interfaces at the physical layer to form a single link layer interface, also known as a link aggregation group (LAG) or bundle. These aggregated Ethernet interfaces help to balance traffic and increase the uplink bandwidth. See Understanding Aggregated Ethernet Interfaces and LACP for Switches.
Why are different IP addresses used in different networks?
A system called Network Address Translation, allows the addresses to be rewritten when packets traverse network borders to allow them to continue on to their correct destination. This allows the same IP address to be used on multiple, isolated networks while still allowing these to communicate with each other if configured correctly.
Which is part of the address refers to the subnet?
Subnet mask – A 32-bit combination used to describe which portion of an address refers to the subnet and which part refers to the host. Interface – A network connection. If you have already received your legitimate address (es) from the Internet Network Information Center (InterNIC), you are ready to begin.
