Maximum Transmission (MTU) Flashcards
(10 cards)
What does Maximum Transmission Unit (MTU) refer to?
The largest size of a frame that can be set over a network
Measured in bytes, MTU dictates data transmission capacity.
How does a properly configured MTU impact network performance?
Enhances network performance and efficiency
Ensures optimal data packet and frame size.
What happens if the MTU is set too high?
Packet loss and retransmission
This can lead to decreased network performance.
What is the effect of a low MTU setting?
Increased overhead and slow network
This can hinder the efficiency of data transmission.
What is the standard MTU size for Wired Ethernet?
1500 bytes
This size is chosen for efficiency and compatibility.
Why is the MTU size smaller in Wireless Networks?
Due to instability and higher error rates
Wireless environments often require adjustments to MTU.
What MTU size is recommended for VPN and PPPoE connections?
1400 to 1420 bytes
This is necessary due to encapsulation overhead.
What are Jumbo Frames?
Frames exceeding standard 1500 bytes
Typically configured at 9000 bytes and beneficial for high bandwidth applications.
What challenges are associated with Jumbo Frames?
Not all network equipment supports jumbo frames
Fragmentation may occur with smaller MTU devices and limited support in traditional tools.
What is necessary for proper configuration when using Jumbo Frames?
Consistent configuration across all network devices
This ensures smooth operation and prevents issues.
