You are performing a network readiness assessment for a Cisco Webex Room Kit deployment. The current network uses a legacy infrastructure with a MTU of 1500 bytes. What is the recommended practice for handling potential fragmentation issues for video traffic streams?
Trap 1: Force fragmentation by enabling ICMP unreachable messages.
Fragmentation significantly increases latency and packet loss probability.
Trap 2: Reduce the video resolution to 360p to keep packet sizes small.
This reduces quality unnecessarily rather than fixing the network transport.
Trap 3: Disable QoS to allow larger packets to traverse the path.
Disabling QoS will likely cause drops due to buffer starvation.
- A
Implement Jumbo Frames (MTU 9000) across the entire media path.
Jumbo frames reduce the number of packets and potential fragmentation overhead.
- B
Force fragmentation by enabling ICMP unreachable messages.
Why wrong: Fragmentation significantly increases latency and packet loss probability.
- C
Reduce the video resolution to 360p to keep packet sizes small.
Why wrong: This reduces quality unnecessarily rather than fixing the network transport.
- D
Disable QoS to allow larger packets to traverse the path.
Why wrong: Disabling QoS will likely cause drops due to buffer starvation.
