What do you understand by FDDI?

FDDI stands for Fiber Distributed Data Interface. It is a set of ANSI and ISO guidelines for information transmission on fiber-optic lines in Local Area Network (LAN) that can expand in run upto 200 km (124 miles). The FDDI convention is based on the token ring protocol.

Where is FDDI used?

FDDI is used mainly in mission critical and high traffic networks where large amounts of data flow need to flow quickly and efficiently. FDDI is used anywhere that utilizes a large network in need of high bandwidth.

What is FDDI explain the features of FDDI?

It provides high data rate of 100 Mbps and can support thousands of users. It contains two token rings, a primary ring for data and token transmission and a secondary ring that provides backup if the primary ring fails. FDDI technology can also be used as a backbone for a wide area network (WAN).

What is FDDI VLAN?

An FDDI VLAN represents a single logical ring with one ring number. You configure FDDI media-specific characteristics only for VLAN Trunk Protocol (VTP) global advertisements to other switches. To configure FDDI-specific VLAN characteristics: In the VLAN ID field, enter the number of the FDDI VLAN.

Which topology is used by FDDI?

ring topology
The emerging Fibre Distributed Data Interface (FDDI) uses a dual counter-rotating ring topology based on optical fibre links.

Why is FDDI important?

The Fiber Distributed Data Interface (FDDI) provides high-speed network backbones that can be used to connect and extend LANs. Fiber-optic cable such as the cable used with Fiber Distributed Data Interface (FDDI) can support very large volumes of data over large distances.

Which type of physical topology is used by FDDI?

FDDI uses both a logical and physical ring, but Token Ring is a logical ring topology that runs on a physical star, for example. If you see the word “ring” on the exam, check the context to see if it is referring to physical ring, logical ring, or both.

Is VLAN 1000 reserved?

By default, the range of reserved VLANs is from 4064 to 4094. Here, VLANs 1000 to 1030 are configured as reserved VLANs.

Can I use VLAN 1002?

1.1) Different Cisco Catalyst switches support various numbers of VLANs. For example, the Catalyst 2960 and 3560 Series switches support more than 4000 VLANs. Normal range VLANs on these switches are numbered 1 to 1005 and extended range VLANs are numbered 1006 to 4094.

What is Token Ring technology?

Token Ring is a computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE 802.5. It uses a special three-byte frame called a token that is passed around a logical ring of workstations or servers.
