Ethernet Switching Features Flashcards
What is a Data VLAN?
A Data VLAN is a network segment that separates data traffic to improve security and performance by isolating network traffic within a specific group
What is a Voice VLAN?
A Voice VLAN is a separate VLAN dedicated to voice traffic to ensure high quality of service (QoS) for VoIP calls.
What is port tagging/802.1Q?
Port tagging (802.1Q) is a method to identify and separate VLAN traffic on a network by tagging Ethernet frames with VLAN information.
What is port aggregation?
Port aggregation combines multiple physical network links into a single logical link to increase bandwidth and provide redundancy.
What is Link Aggregation Control Protocol (LACP)?
LACP is a protocol used to manage the bundling of multiple physical links into a single logical link, providing redundancy and increased bandwidth.
What are duplex and speed settings in port configurations?
Duplex: Refers to the direction of data transmission, either full-duplex (both directions simultaneously) or half-duplex (one direction at a time).
Speed: Refers to the rate of data transmission, typically measured in Mbps or Gbps
What is flow control in networking?
Flow control manages the rate of data transmission between two devices to prevent congestion and ensure reliable data transfer.
What is port mirroring?
Port mirroring copies network traffic from one port to another for monitoring and analysis purposes.
What is port security?
Port security restricts access to a switch port based on MAC addresses to prevent unauthorized devices from connecting to the network.
What are jumbo frames?
Jumbo frames are Ethernet frames with a payload greater than the standard 1500 bytes, used to improve network performance by reducing overhead.
What is Auto-MDI-X?
Auto-MDI-X automatically detects and configures the network port to the correct crossover or straight-through cable type, eliminating the need for crossover cables.
What are MAC address tables?
MAC address tables store the MAC addresses of devices connected to each port on a switch, used to direct traffic to the correct destination.
Describe PoE
Delivers up to 15.4 watts of power over Ethernet cables to devices like IP phones and wireless access points.
Describe PoE+?
Provides up to 25.5 watts of power for higher power devices.
What is Spanning Tree Protocol (STP)?
STP prevents network loops in Ethernet networks by creating a tree-like topology and blocking redundant paths.
