VLAN Configuration (obj 2.2) Flashcards
(23 cards)
What does VLAN stand for?
Virtual Local Area Network
VLANs offer flexibility, performance, and security in network design.
Why is proper configuration essential for VLANs?
To ensure optimal performance and security.
What is 802.1Q Tagging?
An IEEE standard that facilitates the management of multiple VLANs on a single network.
What does 802.1Q Tagging insert into Ethernet frames?
VLAN tags containing VLAN identifiers (VIDs).
What is trunking in the context of VLANs?
Transmission of traffic from different VLANs across the same physical network infrastructure while keeping that traffic separate and secure.
What is a Native VLAN?
The VLAN on a trunk port that does not get tagged with VID.
What is the purpose of a Native VLAN?
It serves as the default VLAN for untagged frames.
Why should the Native VLAN be consistently configured across interconnected switches?
To avoid misrouting.
What is a Voice VLAN?
A dedicated VLAN for voice traffic (VoIP).
What does a Voice VLAN ensure?
Quality and reliability of voice communications.
What is the application of QoS policies in a Voice VLAN?
To enhance voice call quality.
What is Link Aggregation also known as?
Port channeling or bonding.
What does Link Aggregation do?
Combines multiple network connections into a single logical link.
What are the benefits of Link Aggregation?
Enhances bandwidth capacity and provides redundancy for network availability.
Where is Link Aggregation commonly used?
In trunking lines between switches and for high-speed connectivity in data centers.
What do Speed and Duplex Configurations determine?
The rate of data transmission and the mode of communication between network devices.
What does Speed refer to in network configurations?
The rate of data transfer (Mbps or Gbps).
What does Duplex refer to in network configurations?
How data is sent.
What is Half duplex?
A mode where a device can either send or receive data, but cannot do both at the same time.
What is Full duplex?
A mode that allows a device to send and receive data simultaneously.
What can misconfigurations in network settings impact?
Network performance and throughput.
What is auto-negotiation in network configurations?
A process where devices automatically select the highest performance settings they have in common.
When should manual configurations be considered?
For specific requirements.
